1.0 EXECUTIVE SUMMARY
RPS was engaged by Meta Petroleum Corporation (Meta) to perform a reserves certification
report effective December 31, 2009. The field has produced for a number of years and has a
significant reserves base remaining. An aggressive drilling program has been pursued to
develop the majority of the remaining reserves prior to the expiration of the Rubiales and Piriri
concessions. Given the reservoir performance to date and the associated development plan, the
drilling program should continue to be successful and oil production will increase considerably as
the work proceeds.
All reserves volumes in the field are categorized as proved, probable or possible based on the
definitions in the Petroleum Resource Management System of the Society of Petroleum
Engineers. Many of the wells to be drilled are in the probable and possible categories some
distance from the currently developed area; those volumes are unrisked in this report as is the
value placed on those volumes. The present value of the reserves was calculated at a ten
percent discount rate using a price forecast developed by the Strategic Planning Department of
RPS in London. All costs associated with the development of the reserves, including drilling,
infrastructure and water disposal wells are included.
The table below provides a summary of the reserves and value by each reserves category.

RPS Reserves Certification Report
R01002 2 February 2010
RPS has updated the mapping of oil initially in place (OIIP) for the field to a new total of 4,248
MMstb, up from 3,886 MMstb calculated as of year-end 2008. This represents an increase of
362 MMstb (9.3 percent) and is due to updated geological mapping using data from 2009 drilling
and revised petrophysical analysis. Accounting for the 2009 production of 25.1 MMstb from the
field, the year-end 2009 reserves represent an increase in estimated total concession date
recovery of 146 MMstb at the proved level, and 90 MMstb at the proved and probable level.
The series of tables listed below show the results of the reserves, production, cash flow and
present worth calculations:

Table 1.8 Summary of Production Estimates – Proved, Probable and Possible Categories
The field wide proved, probable and possible reserves volume is 501 million barrels
(representing 11.8 percent of the oil initially in place) of which 83.2 percent is proved. Additional
resources that were not included in the evaluation were identified in areas adjacent to the
possible drilling locations and in outlying areas of lower thickness pay sand. The recovery
potential of these resources and economically recoverable volumes beyond the concession
expiry date is an additional 279 MMstb (6.6 percent OIIP). Coupled with the cumulative
production to year-end 2009 of 57.6 MMstb (1.3 percent OIIP) the potential ultimate recovery is
838 MMstb for a total potential recovery of 19.7 percent OIIP.
All references to costs and values in the report are in United States dollars. The net present
value reported is unrisked and does not represent the fair market value of Meta‟s ownership in
the Rubiales Field. A site inspection of the field, including existing wells, facilities, tanks and
pipelines as well as many major construction projects, was made on December 15, 2009. The
data provided by Meta was the sole source of information for this report.

2.0 CONCLUSIONS
This reserves certification report was prepared using field data and an investment program as
provided by Meta. The conclusions noted below relate to depletion of the existing wells and
implementation of the field development plan as it has been proposed.
The drilling campaigns in each of the past years have been very successful in finding and
developing oil and in validating the geological model and engineering projections from
earlier studies.
Due to Meta‟s higher working interest, the Piriri concession reserves have more value to
Meta than the reserves to be produced from the Rubiales concession.
Certain step-out locations that were some distance from proved reserves have been
drilled successfully, and as a result significant areas of the reservoir have had crude
volumes re-categorized to proved reserves much sooner than if the drilling program been
restricted to the proved undeveloped locations.
Production and cash flow have been maximized since the pipeline capacity has been
developed on schedule and the water disposal wells and facilities are being drilled and
built as needed to avoid or minimize the curtailment of production due to transportation or
processing limitations.
The production can be developed for a relatively low cost per barrel. Adherence to the
accelerated rig program will increase the recovery factor as high as it can be before the
concession expires.
An analysis of the historical drilling program results, in contrast to the remaining areas to
be drilled, indicates that future drilling will result in lower recovery per well due to the
thinning nature of the sand on the flanks of the structure.

3.0 FIELD OVERVIEW
3.1 Ownership
The Rubiales Field is located in the Llanos Basin on the eastern side of Columbia as shown in
Figure 3.1, the “Location Map”. Meta‟s working interest in the Rubiales Field is comprised of a
50% ownership in the Piriri concession (62,432 acres in size) and a 40% ownership in the
Rubiales concession (88,463 acres in size). The boundaries of the properties are shown in
Figure 3.2, the “Concession Map”. The Rubiales field is productive from 135,361 acres, which
comprises the majority of the entire extent of the concession area of 150,895 acres.
Meta pays a 20% royalty on working interest production. There are no other burdens or
overriding royalties associated with the concessions. The agreements expire on July 1, 2016.
This relatively close expiry date is the incentive to Meta to develop the field quickly and produce
field reserves as soon as possible.
3.2 Development History
The Rubiales field was discovered in 1981 by Exxon in association with the Tethys operating
group. Three wells were drilled from 1981 to 1982 and on July 1, 1988 a 28 year concession
was granted. Exxon then drilled 14 wells from 1988 to 1993. The field was then acquired by
Coplex Resources in 1994 who drilled 5 additional wells by 1997. Due to financial problems
within the company, the field was shut in until Tethys et al re-acquired it from Coplex in 2000.
Production was re-started in 2001 and two additional wells were drilled for a total of 24 wells at
that time.
In mid-2002 Rubiales Holdings acquired Tethys et al and quickly drilled 14 wells while improving
field operations. In 2004 Meta Petroleum became the operator of the Rubiales field following a
merger of the “et al” companies with the result being a 50% ownership in the Piriri concession
and a 40% ownership in the Rubiales concession. In 2005, studies conducted by Meta
confirmed the significant potential of the field and an investment program was approved.
From 2006 to the present Meta has conducted an aggressive drilling program that has resulted
in a current total of 139 producing wells that are pumping approximately 102,000 barrels of oil
per day at year end. During 2009, the field produced 25.1 MMstb of oil and at year-end had a
cumulative production of 57.6 MMstb. The results of this program are indicated on the field
RPS Reserves Certification Report
R01002 5 February 2010
production plot, Figure 3.3, and on the production plots for the Rubiales and Piriri concessions
on Figures 3.4 and 3.5, respectively. As of year-end 2009, in the fully developed areas of the
field, the wells have been drilled on an average spacing of 81 acres. At year-end 2009, the field
had the following well count:
Production Vertical 38
Horizontal 101
Disposal Vertical 3
Horizontal 12
Shut-In Vertical 59
Horizontal 15
Abandoned Vertical 8
Horizontal 0
Total wells Vertical 108
Horizontal 128
Grand total wells 236
Meta has scheduled an additional 536 wells to completely develop the field during the next six
years. RPS has classified the wells as proved, probable and possible drilling opportunities.
Meta has also scheduled 151 locations to which RPS has assigned resource volumes.

4.0 GEOSCIENCE
Geological Model for Entrapment
The geological model for the Rubiales field (proposed by RPS Scotia in 2007) was a
hydrodynamic trap, with oil trapped by basin ward (northwestward) flowing formation waters
trapping oil under a broad subtle structural nose at the top of the fluvial/alluvial Arenas Basales
Formation. This trapping model is supported by a tilted oil water contact, pressure data in the
reservoir section, log facies characteristics of available wells, and regional geologic information.
The mapping method used to define prospective areas, using this geologic model, was the
Trend Residual mapping method where subtle structural highs are identified as positive
anomalies with a positive residual value when compared to the regional structural trend.
The geological tops for 29 new well logs that were provided to RPS during 2009 continue to
support a tilted oil water contact. The oil-water contact and whether or not an area would be oil
bearing for a well drilled within the current producing field area can be predicted using the
hydrodynamic/tilted oil water contact model. Water productive wells are still located on structural
anomalies. However, the RPS hydrodynamic model is not predictive of oil production extending
outside the current producing area, given the current data available. The limits of the field do not
appear to have been defined and appear to lie outside the concession area. Without more
regionally extensive dry hole data delineating non-productive areas, a Trend Residual mapping
method is not useful to predict a Rubiales field productive extension. A brief mapping exercise
suggests that it is probable that more complex stratigraphic and hydrodynamic trapping elements
are involved in defining the geological limits of Rubiales oil production.
Geological Work Performed
New well locations and new well logs (LAS files) for the 29 vertical wells drilled during 2009 were
loaded into an existing Petra project file. Geological tops from Metapetroleum were also loaded
to the Petra Project file. Thirty seven additional horizontal wells have been drilled in 2009, but
LAS files and directional survey data on these wells were not made available to RPS.
The new producing wells and wet wells were inserted into the existing cross sections, and
additional cross sections were constructed, incorporating the new vertical wells. (Tops were not
used on RB 159 and RB 42H wells as directional survey data were not available.) RPS has over
RPS Reserves Certification Report
R01002 7 February 2010
a 90% agreement with the observed Meta geological tops. Any top discrepancies were
generally less than 10 feet of difference. Additional geological tops were picked for new wells.
These tops were incorporated into the cross sections and the geological maps.
Based on the new well data and new tops, several of the existing maps, such as the Structure
Top Arenas Basales, Structure Oil Water Contact Arenas Basales, Gross Arenas Basales
Interval, Net to Gross Sand Ratio Arenas Basales Reservoir Interval, Gross Isopach Pay
Interval, and Net Pay Isopach were updated and re-contoured in the Petra Project.
The Structure Top Arenas Basales map (Figure 4.1) shows monotonous northwest dip into the
basin. Almost all of the new wells drilled in 2009 in the Rubiales field fit the tilted water table and
hydrodynamic entrapment model as shown on Figure 4.2, the Structure Oil-Water Contact. The
cross section in Figure 4.3 documents this fit and demonstrates the tilted oil water contact.
Water productive wells are located on structural anomalies as noted by the contours near the
blue highlighted water wells in Figures 4.1 and 4.2.
The Arenas Basales Gross Reservoir Isopach map shows a northwest trending thick interval
(Figure 4.4) while the Net/Gross sand ratio map of this same interval shows the northwest
trending reservoir thickening is actually higher in shale content (Figure 4.5). The Net Pay
Isopach map shows an east-west trending pay interval which cuts across the northwest trending
gross reservoir thickening (Figure 4.6). More work would be necessary to define the potentially
more complex stratigraphic trap elements apparent from this observation.
The limits of the Rubiales field have yet to be defined. The current in-field drilling program still
fits the tilted water table and the hydrodynamic trap models. However, the RPS hydrodynamic
model is not predictive of the presence of oil that is known to extend outside the concession
boundaries in areas that remain sparsely drilled or not drilled at all. Without more regionally
extensive dry hole data delineating non-productive areas, the Trend Residual mapping method
done in previous audits (in 2007 and 2008) is not useful. It is likely that more complex
stratigraphic and hydrodynamic trapping elements are involved in defining the geological limits of
Rubiales oil production.

5.0 PETROPHYSICS
The petrophysical work used in this analysis includes the review of the existing static model of
the Rubiales Field, the validation of the petrophysical parameters and models, and an update to
the existing static model with information from 29 new wells (Figure 5.1). The objective was to
provide necessary petrophysical information in terms of Clay Volume (VSH), Effective Porosity
(PHIE), Water Saturation (Sw) and Oil-Water Contact (OWC) depths to be integrated into the
geocellular model for the volumetric estimation of the oil initially in place (OIIP) and to support
the development plan of the field. The project was developed in the RPS office in Houston with
interaction with Meta specialists incorporating the new well logs and core data.
An audit of all petrophysical input parameters and models used in the petrophysical evaluation of
the wells was performed using the specialized software Interactive Petrophysics version 3.5.5.0,
concluding that input parameters, models used, and results obtained from the petrophysical
evaluation are reasonable. The available data for the petrophysical review was considered
sufficient in terms of quantity, quality and consistency. A comparison of log-derived porosity and
water saturation against core-derived porosity and water saturation was also done with an
excellent fit. The determination of net pay thickness from the petrophysical modeling is also
considered accurate.
The OWC can be established from visual analysis of the log curves signature, corresponding to
a decrease of the Deep Resistivity curve into a range of 20 to 30 Ohm-m in front of a porous
sand body. The petrophysical model matches this response with 100 percent water saturation
below the OWC, and low water saturation values above the OWC. The variation in depth
indicates a tilted OWC associated with the hydrodynamic mechanism acting in the Llanos Basin.

R01002 9 February 2010
6.0 STATIC GEOCELLULAR MODEL
The geocellular model of the Rubiales field that was generated by Meta during 2009 was
analyzed and validated. The model was then updated using seismic data, well log correlations,
stratigraphic data, facies studies and a petrophysical evaluation. Volume calculations of oil
initially in place were carried out to support the reserves certification objective and also to
validate the field development drilling program.
The geocellular model of the Rubiales field was constructed in three steps:
Structural Framework - The geometry or structural framework of the model was created
through the three-dimensional integration and matching of well locations and paths,
geological tops, and fault surfaces.
Grid Cells - The volume of rock contained within the structural framework was divided in
zones and layers and subdivided into small boxes or grids (cells). This procedure
generated more than 5,400,000 cells. In this step, the cells penetrated by wells (Cell-
wells) were populated with facies information and petrophysical parameters, using
averaging methods as arithmetic mean, root mean square, harmonic mean, midpoint
pick, etc. The facies population of the cell-wells was carried out based on facies logs and
stratigraphic-sedimentary models that were determined previously.
Extrapolation of Properties - The values within the „cell-wells‟ were distributed by
interpolation through all the model cells. The distribution was carried out applying
deterministic and stochastic algorithms, looking for the best distribution of discrete and
continuous data through each cell of the geocellular model. The final version of the
geocellular model of the Rubiales field is a scaled representation of the real oilfield where
the geological characteristics and fluid conditions can be studied, analyzed, quantified,
simulated and predicted.
The geocellular model was generated using Petrel software. The main components of the
geocellular model were the structural model, facies model and petrophysical model.
The structural model includes geological tops and fault surfaces that have a relationship with
fluid control. The structural model was created using six geological tops from the top of the
Arenas Basales to the top of the Paleozoic, originating five lithological zones. Each lithological
RPS Reserves Certification Report
R01002 10 February 2010
zone was divided into layers. A total of 65 layers were created and divided into 50m x 50m cells
to get the cellular model frame with more than 5,400,000 cells.
The facies model was created by Meta using log analysis, core descriptions and sequence
stratigraphic concepts. The reservoir quality facies corresponds to isolated filled channels (CH),
stacked channel deposits (S-CH) and crevasse channel deposits (C-CH). The non-reservoir
facies are defined as single crevasse splay (SC) and over bank deposits (O).
The petrophysical evaluation was used in the update of the Rubiales geocellular model.
Detailed analysis of the well data evaluation was performed, and then several calculations of
new parameters were generated. Clay volume (VSH), effective porosity (PHIE), water saturation
(Sw) and net to gross sand ratio (NTG) were up scaled and loaded in the cell-wells. These data
were analyzed to determine the spatial characteristics of the data through histograms, trends
and variograms. This is an important and time-consuming process, which allowed determining
the best input parameters to deterministic and stochastic algorithms.
The cells penetrated by well paths (cell-wells) were populated with information derived from
facies and petrophysical data using averaging methods as arithmetic mean, root mean square,
harmonic mean etc. Very few cells are penetrated by wells. Previous to the stochastic spatial
distribution of cell-well values thru all the cells, data analyses were applied for quality control and
to characterize the cell values. In this process vertical proportionality, thickness variations,
histograms, trends and vertical and horizontal variograms of the cell values were generated,
analyzed and quantified. These spatial data characteristics became the input parameters used
for the stochastic algorithms in the stochastic spatial distribution of data through all the cells.
Hundreds of variograms were generated and analyzed in order to get the best possible strike
direction and trend for each facie, petrophysical parameter, and correlation facie-petrophysical
property.
Several deterministic and stochastic algorithms were tested in order to determine the best spatial
distribution of discrete (facies) and continuous (porosity, water saturation, etc.) data.
Facies data and petrophysical properties were spatially distributed to each cell, using the
Sequential Indicator Simulation algorithm. The petrophysical properties were conditioned to the
facies results.

R01002 11 February 2010
Finally, the geocellular model of the Rubiales field was created for a set of volumes divided into
millions of cells, embedded with lithology, porosity, water saturation and facies data. Figures 6.1
through 6.4 show the final distribution of these properties in the 3D model. This is the basic data
used in the oil initially in place (OIIP) volume calculation in the geocellular model. A contour map
that showed contours of stock tank oil initially in place (STOIIP) was also created (Figure 6.5).
The contours represented the STOIIP for a 50 meter by 50 meter cell surface area with a vertical
capture of the entire net pay sand thickness for the five sand members in the cell.
The volume calculation areas were defined by polygons representing the concession
boundaries. The productive and concession areas contained in the Petrel model are shown
below:
Rubiales Piriri Total
Productive Field Area (acres) 83,590.6 51,770.2 135,360.8
Total Concession Area (acres) 88,463.0 62,431.6 150,894.6
The results are grouped in the following table by the five zones determined by the
sedimentological facies in the entire concession area.
STOIIP - MMbbls
Rubiales Piriri Total
Zone 1 1078.7 530.1 1608.8
Zone 2 802.6 446.1 1248.7

Zone 4 69.8 9.8 79.6
Zone 5 0.5 0.00 0.5
Total 2985.1 1262.6 4247.7
These values and the derived STOIIP maps were used as a basis for much of the reservoir
engineering calculations in the study to aid in the reserve certification and support the proposed
field development drilling program.

7.0 RESERVES DETERMINATION
7.1 Discussion
The Rubiales field contains low gravity, highly viscous oil. The recovery mechanism in the field
is primary recovery, with strong pressure support from a bottom water aquifer. In such a field,
the recovery factors under traditional oil field developments using vertical wells can be expected
to be relatively low, in the range of 10 percent to 20 percent of OIIP. RPS analysis indicates that
the maximum recovery factor of 20.3 percent can be expected for this field. To maximize the
recovery efficiency, Meta has pursued a development drilling plan that will increase the well
density and incorporate a significant number of horizontal wells.
The Rubiales field crude oil has low solution gas content, as represented by the gas-oil-ratio that
is estimated to be 5 scf/stb. As a result, there is insufficient produced gas to warrant gas sales.
Some produced gas is used as field fuel and the balance is flared. RPS has not attributed any
gas reserves to the field.
Two separate concessions hold the reserves in the Rubiales field. Each concession has a
unique operating and net revenue interest, thus the reserves and economics are calculated
separately for each concession and then summed to get the fieldwide figures.
7.2 Developed Reserves
Reserves estimates were made using production performance analysis, volumetric estimates
and production analogues. Analysis of the change in production rates, water-oil ratio and oil cut
as a function of cumulative production and time was performed to predict the ultimate
recoverable volumes for the producing wells. Parameters used to specify the shut in conditions
were two percent oil cut at a producing rate of 30 and 150 barrels of oil per day for vertical and
horizontal wells, respectively. These minimum operational production rates are dictated by
water handling capacity limitations and not due to an economic limit or flow assurance problems.
An exponential decline curve shape was used for the rate forecasts, with application of
hyperbolic performance where well performance supports the projection after the initial flush
production. Plots of the oil rate versus cumulative production, oil cut versus cumulative
production and water oil ratio versus cumulative production for the producing wells were
reviewed.
RPS Reserves Certification Report
R01002 13 February 2010
Reserves for wells that were completed within the past few months that have not had sufficient
production decline performance were determined by using the type well analogies that were
applied to the drilling locations for the undeveloped reserves. All of the type wells are located in
the field, have perforated the subject sand interval, and have sufficient performance history to be
a good basis for rate projections.
As of December 2009 there were 74 wells in the shut in classification. Most of the wells have
prior production history, a lesser number have been tested only and have no cumulative
production. Meta has advised that 60 of these wells are scheduled to be placed on production in
2010 and 2011. These wells were forecasted and scheduled, and the reserves were included in
the proved developed non-producing category. The 14 remaining shut in wells are assumed to
have no potential since they were not part of the re-vitalization program.
The Rubiales field has been developed with 221 vertical and horizontal wells which have
indicated typical drainage areas of 50 and 87 acres, respectively. The typical drilling program
involves a centralized vertical well with five horizontal wells drilled outward from the same pad
location. A well cluster of this design typically drains an area of 485 acres. The horizontal wells
typically drill a distance between 500‟ and 1,200‟ feet through the reservoir. The recovery from
the horizontal wells exceeds that of the vertical wells. The wells have different performance
characteristics also. The vertical wells initially exhibit a lower average annual exponential
decline rate, and the horizontal wells initially produce at a much higher rate with a hyperbolic
decline. Table 7.1 lists all the wells that have been drilled in the field with the cumulative
production, proved reserves and estimated ultimate oil recovery of each.
The cumulative field production to year end 2009 was 57.6 MM barrels of oil, and the proved
reserves for the producing wells on December 31, 2009 are 94.1 MM barrels of oil. The ultimate
recovery (to the end of the concession term on June 30, 2016) from all wells drilled to date is
estimated to be 151.7 MM barrels of oil.
The reserves that were determined by performance analysis were checked against volumetric
calculations. Table 7.2 is a volumetric calculation that was performed to determine the oil initially
in place per acre-foot and a “maximum case” recovery efficiency for the field. The table
indicates oil initially in place of 1,450 barrels per acre-foot using the average reservoir
parameters of 26.4% porosity and 27.5% water saturation. Using a sweep efficiency of 85%, the
RPS Reserves Certification Report
R01002 14 February 2010
recovery efficiency is 20.3% giving a recovery of 294 barrels per acre-foot. The 20.3% recovery
is considered a theoretical maximum, recognizing that not all the zones in each well will be
depleted due to mechanical and operational failures, unswept reservoir areas and bypassed oil
in zones that were not perforated.
A number of the wells have been drilled but have a short production history, thus performance
plots could not be used to forecast the production or to estimate the reserves for these wells.
These wells were classified as “proved developed producing” and assigned reserves using the
type curve method used for drilling locations (as described in the next section) based on
volumetric calculations and analogy. These wells with the associated proved reserves are
shown in Table 7.1 and given “well analogy” as the reserve basis.
The oil initially in place within the concession area, as calculated using the updated geocellular
model, is 4,248 MM stb. The concession area includes undrilled acreage on the flanks of the
structure that lies outside of the developed portion of the field. This untested area is evaluated
to be oil bearing based on a depositional analysis and available geological technical data which
indicates the pore volume is above the original oil water contact. The potential fieldwide oil
recovery using the 20.3% recovery factor would be 861 MM stb. This volume would include the
3P reserves contained in the cash flow analysis plus oil volumes from locations that are currently
captured in the “resource” category, which are volumes that lie outside the possible reserves
areas, volumes from wells that have been produced but in which all zones have not been
perforated, and economically recoverable volumes produced beyond the current concession
license expiry date.
7.3 Undeveloped Reserves and Resources
To estimate the reserves potential of the drilling program, a statistical analysis of past production
was used in combination with the Petrel static model. The net pay sand of the wells that have
sufficient performance to perform decline curve analysis was plotted against the estimated
ultimate recovery for both the vertical and horizontal wells. Table 7.3 shows that the 39
horizontal wells were drilled in thicker pay sections (50‟ average) than the 31 vertical wells (26‟
average), and that the horizontal wells have an average recovery that is higher than the vertical
wells, 1,325,000 stb versus 620,000 stb, respectively.
RPS Reserves Certification Report
R01002 15 February 2010
A total of 687 locations that were included in Meta‟s development plan have been evaluated.
The wells were reviewed separately for each concession (Rubiales with 566 and Piriri with 121)
since the ownership is different for each property. The reserves determination was done in two
phases:
1. Assignment of reserves category based on proximity to production, and
2. Assignment of reserves volumes based on Petrel STOIIP cell values.
Phase 1
A base map containing the existing producing wells and Meta‟s proposed drilling locations was
used to assign the reserve classification based on proximity to production. Proved reserves
were assigned to new locations in areas that are undrilled and adjacent to existing wells within
the proved area of the reservoir that could reasonably be judged as continuous and being
commercially productive on the basis of available geoscience and engineering data. Probable
reserves were assigned to areas of the reservoirs that were adjacent to proved areas but where
data control or interpretations of available data was less certain. Possible reserves were
assigned to areas of the reservoirs adjacent to probable areas where data control and
interpretations of available data were progressively less certain.
Areas of the reservoir where the Petrel model indicated the reservoir should be present outside
of the proved, probable and possible areas were designated as areas in which Meta‟s proposed
wells would be drilled for oil volume in the resource category. The wells needed to develop
these resources were given drilling location names and volumes, but production and cash flow
projections were not made.
Six hundred eighty seven locations were classified as follows:
Proved 341 locations
Probable 91 locations
Possible 104 locations
Resources 151 locations
RPS Reserves Certification Report
R01002 16 February 2010
Phase 2
Each of the proposed locations was identified on a fieldwide Petrel map that showed contours of
stock tank oil initially in place (STOIIP), Figure 6.5. The contours represent the STOIIP for a 50
meter by 50 meter cell surface area with a vertical capture of the entire net pay sand thickness
for the one to five sand members in the cell. Values for the contours ranged between 0 to
70,000 barrels per cell, although few wells remain to be drilled in contours over 40,000 since the
thicker pay sand areas have been effectively exploited by Meta.
Wells that have produced that are either depleted or that have reserves based on performance
are listed in Table 7.3. The estimated ultimate recovery and the net pay are tabulated for each
well, indicating the average estimated ultimate recovery and average net pay for vertical and
horizontal wells is 620,000 barrels and 26 feet of net pay, and 1,325,000 barrels and 50 feet of
net pay, respectively. The scatter to the data suggests that a definitive relationship between the
parameters may not be present and that the recovery from proposed locations is difficult to
predict from the net pay isopach map.
A second data set is shown on Table 7.4 for the relationship between the estimated ultimate
recovery and the STOIIP contour map from the Petrel model. This data is also scattered such
that the plot based on STOIIP values is not a good indicator of recovery from the proposed
locations. The average estimated recovery for each STOIIP cell value for a vertical and
horizontal well is 14.0 and 44.5 barrels, respectively.
Despite the scatter in the data relative to Tables 7.3 and 7.4, the average relationships are
reflective of the historical production data and are valid for the prediction of estimated reserves
for large numbers of locations such as those within the Meta drilling program. The earlier
geological discussion describes the hydrodynamic trap model with the tilted oil water contact
across the field, indicating the existence of many individual reservoir lobes with lateral barriers
that produce independently. Absent knowing the structure and extent of each of the lobes,
determination of the drainage area for each well (thus the reserves) will be best established
using the statistical methods based on past well performance as indicated.
The determination of reserves and production forecasts for each location was made from the
following calculations:
RPS Reserves Certification Report
R01002 17 February 2010
1. The estimated ultimate recovery per STOIIP contour for vertical and horizontal wells
having production history was determined as shown on Table 7.4 to be 14.0 and 44.5
barrels per STOIIP contour per cell unit.
2. The estimated reserves for future locations were calculated using the above recoveries
multiplied by the discrete STOIIP contour from 4,000 to 60,000 where the wells are
spotted to be drilled.
3. The type curves shown on Figure 7.1 were generated based on past performance (initial
flowrates and decline rates) and matched to the associated reserves volumes.
4. The production type curve and reserves volume from these analogies were used for each
location that was scheduled to be drilled prior to the end of the concession period.
To ensure that all wells that were scheduled meet a profitability test, calculations to determine
the minimum reserves needed to drill a profitable well were performed. The average well cost
and the economic parameters that impact the profit calculation were used. The reserves needed
to drill and produce a vertical or horizontal well are 54,500 and 70,400 barrels, respectively.
Considering the different areas that a vertical versus a horizontal well would drain assuming a
thin pay sand interval, the associated Petrel STOIIP contours are approximately 5,400 and 4,400
stb OIIP per grid cell for vertical and horizontal wells (for net pay intervals of 6‟ and 5‟,
respectively.
The highest recovery from a vertical well and a horizontal well having performance from the plots
on Table 7.3 was 1.5 million and 3.2 million barrels, respectively. It is anticipated that none of
the wells drilled in the future would produce volumes approaching these figures.
In summary, there are 536 locations having 380 MMbbls of proved, probable and possible oil
reserves and 151 locations having 114 MMbbls of oil resources, with these volumes being the
total volume recoverable prior to depletion based on the locations that were provided by Meta.
One condition for undeveloped reserves potential to be included in this report as reserves is to
have a stated intention by the operator to drill the wells. Meta has indicated their intention to drill
the wells and has provided the drilling schedule for 2010, which was used as guidance to
continuing the drilling program through 2015. The majority of the locations in the earlier years
are proved wells, with the majority of the probable and possible locations being drilled in the later
years. Meta has indicated that in the later years of the concession, locations in the resource
category that have an expectation of at least 10‟ of net pay sand would be drilled.

8.0 PRODUCTION FORECASTING
The Rubiales field was discovered in 1981; however it only produced periodically until 2002
when production was reported continuously. After Meta obtained control of the operation of the
field in 2004 the production increased until it reached 100 MBOPD in 2009 (Figure 8.1). The
production for the Rubiales field was forecasted from January 1, 2010 to the expiration of the
concession on June 30, 2016 as shown in Table 7.5. The field has 139 producing wells in the
concessions with the associated reserves volumes during the concession license period as
shown in the table below. These wells comprise the proved producing case.
Sixty shut in wells were scheduled to be back on production between 2010 and 2011. The
production from these wells during the concession period was scheduled. The volumes are
classified as proved non-producing reserves as shown in the following table:
The Rubiales field has 536 locations in the drilling program that is forecasted to continue into
2015. The locations are expected to generate 380 MM barrels of oil before the end of the
concession period. The table below shows the reserves volume split between the proved,
probable and possible categories as well as the number of locations in each.

The production forecasts for each of the drilling programs are shown in the cash flow forecast
evaluations to be discussed in Section 9.0 Determination of Value. Forecasts of the production
performance by reserves category were created following the list of new locations and the 2010
drilling schedule provided by Meta as shown on Figure 8.2. This schedule of development has
assumptions that include the number of rigs that would be contracted by year as well as the time
it would take to drill and complete a typical well. The production forecasts of the field
development plan were scheduled on an unrisked basis.
A total of 64 water disposal wells are planned to be drilled from 2010 through 2015 by Meta.
The wells will be grouped into 11 clusters and the drilling is scheduled as shown below:

9.0 DETERMINATION OF VALUE
9.1 Ownership
Time Period
The assessment of value for the Rubiales field was calculated for the production forecast from
January 1, 2010 through the end of the Piriri and Rubiales concession contracts on June 30,
2016. Both of the concessions expire on the same date; reserves that remain after this date are
not recoverable by Meta Petroleum. The effective date for discounting of field value in the
evaluation is January 1, 2010.
Interests
Meta has different working and revenue interests in the two concessions as follows:
Rubiales Piriri
Working interest 40% 50%
Net Revenue interest 32% 40%
The royalty due from crude oil production that is sold from each concession is 20 percent.
Natural gas production is negligible and is not metered or sold. The economic analysis includes
the crude oil / naptha blend as the sales product. Royalty is paid on the crude oil but not on the
naptha. Thus, the royalty in the economic model is based on a ratio of crude oil at 20 percent
royalty and the naptha that has no royalty obligation. The net revenue share that was input into
the model to properly reflect the ownership of pipeline volume to sales is 81.7 percent.
9.2 Determination of Volumes
Production
The Piriri and Rubiales concessions each have value in the proved producing, proved non-
producing, and proved, probable and possible undeveloped categories. All volumes in this
report are presented unrisked. Appendix 1 is an exhibit that is taken from the Petroleum
Resources Management System (PRMS) report that was issued in 2007 by the Oil and Gas
RPS Reserves Certification Report
R01002 22 February 2010
Reserves Committee of the Society of Petroleum Engineers and was reviewed and jointly
sponsored by the World Petroleum Council (WPC), the American Association of Petroleum
Geologists (AAPG) and the Society of Petroleum Evaluation Engineers (SPEE). The PRMS
report contains guidelines regarding the relative risk and uncertainty of recovery for the various
reserves categories that are contained within this reserves certification report. The reserves and
economics evaluations that were performed in this report followed the guidelines that were
provided in this exhibit. A summary of the well count that is associated with each reserves
category is as follows:
Proved Producing – As of year-end 2009 there were 139 wells producing oil. 68 percent
of the wells are expected to produce through June 2016 when the concessions expire.
Proved Non-Producing – There are 60 wells with past production or tests that are
scheduled to be re-completed in 2010 and 2011.
Proved Undeveloped – 341 locations are in close proximity to prior production.
Probable Undeveloped – 91 locations offset the proved undeveloped locations.
Possible Undeveloped – 104 locations offset the probable undeveloped locations.
Table 7.5 shows the annual production forecast that is developed from the above re-completion
and drilling program for the Rubiales field by concession and reserves category.
Lease Fuel
Some of the oil production is consumed as fuel in the field to heat the crude and enable the
separation of the oil from the water to be more efficient. While the produced volumes have
increased as the field is developed, the fuel volume has increased also. During 2009, fuel
consumption increased from approximately 250 to 450 barrels per day. The current projection of
fuel consumption in 2010 is 1,250 barrels per day, rising to 2,700 barrels per day in 2014 as
shown in Figure 9.1. After 2014 when field production declines, the fuel consumption is
forecasted to decline also to 2,400 barrels per day in 2016. Table 9.1 shows the forecasted
annual crude volume to be consumed. Fuel volume was scheduled by allocation to the proved,
probable and possible reserves categories for each concession.
RPS Reserves Certification Report
R01002 23 February 2010
Sales
The annual production volumes from 2010 through 2016 in each reserves category, by
concession, were reduced by subtracting the oil consumed for lease fuel to determine the crude
volume that is to be sold. The oil volumes that are trucked or pipelined to sales at Covenas for
export are diluted by blending with naptha to increase the API gravity to meet pipeline and/or
sales specifications. This naptha volume plus the crude sales volumes (field production less
lease fuel consumption) comprise the total sales volumes. Table 9.1 shows the annual naptha
purchases and the annual net sales volumes. These sales volumes are the volumes that are
entered into the economic analysis. The costs of naptha purchase and transportation to the field
are treated as a field operating cost. Also, from the present through December 2011 Meta
forecasts the sale of 4,000 barrels per day of 12.5 degree API gravity crude to the local
Columbian market via trucking without the addition of naptha.
9.3 Marketing
Oil Price
The forecasted annual price of WTI benchmark oil was provided by the RPS Strategic Planning
Department in London in January 2010. The produced oil from Rubiales is 12.5 degrees API
gravity, a low gravity that has downward price adjustments due to quality of 17.29 percent and
9.22 percent, for the trucked and pipelined oil, respectively. The oil value is also reduced for
system losses of 3.29 percent and 5.16 percent, for the trucked and pipelined oil, respectively.
These values are based on Meta‟s 2009 sales data. These price adjustments were applied to
the RPS WTI price forecast and proportioned by the relative volumes that were forecasted to be
trucked locally, trucked to Guaduas, or pipelined to Covenas. A weighted average price forecast
was then calculated which is shown in Table 9.2. Trucking of the oil is scheduled to end in
December 2011; afterwards all the oil will be transported through the pipeline.
Transportation
From field discovery through mid 2009, all of the production from the Rubiales field was trucked
to sales. Trucking is very expensive and the excessive traffic damages the dirt roads within the
field. During 2009, Meta constructed and commissioned a 235 km 24 inch pipeline to increase
export capacity, increase safety and lower transportation costs for crude oil from the field.
RPS Reserves Certification Report
R01002 24 February 2010
The pipeline originates in the Rubiales Field and initially transported 65,000 barrels per day in its
first phase. The pipeline goes from the field to Monterrey where it ties into existing pipeline
facilities which transport oil to the Pacific coast at Covenas for the oil to be loaded onto oil
tankers for export. The pipeline routes are shown on Figure 9.2. Because Meta‟s and
Ecopetrol‟s field production will be sold in the pipeline together, the gross field production plus
blended naptha is used to determine transported pipeline volumes. The scheduled growth of
pipeline capacity, to be accomplished by adding more pumping horsepower as the field volume
requires, is as follows:
Added Pumping
Capacity Completion Barrels per day
February 2010 120,000
March 2010 160,000
June 2010 170,000
March 2011 300,000
9.4 Costs
The investment program to develop the Rubiales field reserves with the associated infrastructure
was created in 2007 when the field potential was established. Subsequent drilling and
construction to this date has generally followed the original plan and resulted in a substantial
investment and increase in production during the past two years. The forecasted expenditures
appear to be sufficient to optimize field recovery prior to the expiration of the concessions on
June 30, 2016.
The field development has included drilling producing and water disposal wells, re-completing
shut in wells, building facilities to process produced fluids and to dispose of produced water, an
extensive system of flowlines and water disposal lines, and the construction of tankage and lines
for the purchase, handling and blending of naptha which is necessary to increase the oil gravity
to pipeline specifications.
RPS Reserves Certification Report
R01002 25 February 2010
Investments - Drilling
A typical producing well program consists of one vertical well in a centralized pad location with
up to five horizontal wells drilled outward from the same pad area. Costs for the location
preparation, generators and pipelines are included in the well costs. The drilling well costs were
provided by Meta as follows:
Well Type Cost per well
Production well – horizontal $1,754,000
Production well – vertical $1,657,000
Disposal well – horizontal $1,573,000
Disposal well – vertical $1,296,000
These costs have been reviewed by RPS, including comparison with Meta‟s historical drilling
cost in the field, and deemed to be reasonable.
The timing of the producing well drilling program was scheduled by Meta for 2010 and by RPS
for 2011 and beyond based on the reserves analysis. The costs were assigned by the location
of each well to its concession and reserves category. The schedule for drilling the disposal wells
(timing and well type) was provided by Meta. Disposal well costs were distributed to each
concession and split by the proportional reserves volume in each reserves category. No
disposal well cost was distributed to the proved producing reserves cases because these
volumes already have water disposal capacity.
The drilling program is scheduled to continue uninterrupted into 2015. An analysis of the
horizontal and vertical producing wells indicates that for a horizontal and vertical well to be
profitable, 70,400 and 54,500 barrels of oil, respectively, must be recovered. At the expected
producing rates, the wells would payout in six months or less, making it attractive to continue the
drilling program through 2015.
The cost for a well re-completion was provided by Meta to be $250,000. A review of the shut in
wells across the field by Meta personnel resulted in a list of 60 re-work opportunities that were
reviewed by RPS. An analysis of the past performance of these wells indicates the potential to
re-establish production. The re-completions are scheduled to be completed in 2010 and 2011.
RPS Reserves Certification Report
R01002 26 February 2010
Meta had signed contracts for five drilling rigs in 2008 that kept the rates constant for a three
year period through 2011. Thus, no cost inflation was applied to the well costs until 2012 when a
two percent annual inflation was applied. Meta uses just two types of rigs in the field. By limiting
the rig types to two, operating and maintenance costs are kept as low as possible. The re-
completion well work will be done using smaller rigs that have a two percent cost inflation
beginning in 2010.
The forecasted annual drilling and re-completion investments are shown on Table 9.3.
Investments - Facility
The work to expand the capacity of the field infrastructure continues concurrently with the drilling
program. The metering and processing facilities, water injection pumps and lines, and naptha
blending tanks and equipment to accommodate the increasing production are under
construction. New areas, as developed, will also benefit from infrastructure projects to process
higher volumes of produced fluids. These facility investments were scheduled by Meta and are
shown on Table 9.3. The costs were allocated to each concession and reserves category based
on the percentage of reserves to be recovered. The escalation rate applied to these costs was
two percent.
The costs to manage the rising water production are substantial and projected to increase into
the future. An additional 500,000 bwpd of capacity is scheduled for installation in 2010. At the
various water injection sites, clusters of horizontal injection wells are drilled around a single
vertical injection well, and pump capacity is designed based on the expected water production in
the area. If additional capacity is required due to higher than planned water production, more
pumping capacity is installed rather than the drilling of additional wells. Wells are planned to
dispose of 45,000 bwpd, but are capable of disposing of up to 70,000 bwpd. Produced water is
fresh with essentially no contaminants, and the continued disposal of 300,000 bwpd into the
nearby river is expected.
Expenses - Operating Costs
The operating cost history for the past several years for the Rubiales field has been provided by
Meta. The cost schedules have been reviewed by RPS, compared with historical costs and
deemed to be reasonable.
RPS Reserves Certification Report
R01002 27 February 2010
The monthly costs in 2009 from January through October steadily increased as produced
volume increased from 1.5 to 2.5 million barrels per month. In October, the operating cost was
$9.3 million, or $3.64 per barrel. The trend line shows the costs were on track to reach $3.75
per barrel by year end 2009. An average operating cost of $4.00 per barrel was estimated for
2010. The forecast generated by RPS for this analysis indicated an average 2010 production
volume of 151,500 barrels of oil per day. As a result, the total operating cost that is forecast for
2010 is $221,192,000 which is substantially above the costs in the prior years.
The cost noted above was split at a 35% / 65% ratio between fixed and variable cost
components, respectively. The fixed cost of $77,417,000 that is shown on Table 9.4 represents
the annual operating cost that is independent of the well count or the production volume. To
reflect the growth in field facilities, the fixed cost was increased by five percent in 2011 and
2012, followed by no increase in 2013. The variable cost of $143,775,000 represents operating
costs that will vary with well count and production volume. The variable cost was split at a 35% /
65% ratio between well count and production volume. Variable costs of $286,000 per well
(based on the average 2010 forecasted well count) and $1.69 per barrel (based on the estimated
cost allocated to the forecasted 2010 production) were determined. All operating costs were
escalated at an annual rate of two percent.
In previous year analyses, a road maintenance cost of $0.79 per barrel was added to the
production expense due to the excessive road usage by the oil trucks prior to the construction of
the export pipeline. The road use by the trucks hauling oil has declined considerably now since
the pipeline is in operation, resulting in a less costly road repair program. Meta advised that the
cost of road maintenance is now handled by the army that is stationed in the field.
An additional variable cost that is charged is Meta‟s overhead and administration. Meta advised
that this cost is $0.50 per barrel; it was added to the variable cost of $1.69 to determine the total
variable cost of $2.19 per barrel of produced oil.
Expenses – Naptha Purchase
The produced crude oil has 12.5 degree API gravity, and due to its high viscosity it does not
meet pipeline specifications. Naptha at 82 degree API gravity is trucked to the field and blended
with the crude oil to lower the viscosity. The blended oil has 18.5 degree API gravity, meets
pipeline specifications and sells for a higher price than the unblended produced crude oil. The
RPS Reserves Certification Report
R01002 28 February 2010
oil that is transported by trucks and sold locally is heated in the trucks to reduce its viscosity and
is not blended with naptha.
The required naptha volume is a function of the relative crude oil quality and produced volume
from the Rubiales, Caracara, Ocelote and Quifa fields. The crude oil from these fields is blended
in the pipeline, and the final mixture must be of pipeline quality. The forecasted production,
naptha requirements and pro-rated volume of naptha that is blended with Rubiales crude have
been determined by Meta and furnished to RPS for this analysis. The naptha is purchased for
the posted price of WTI oil less $5.00. The forecast of naptha prices, annual volume
requirement and annual expenditures to purchase the naptha are shown on Table 9.4.
Expenses – Tariffs and Blending
Until the pipeline in the field reaches its maximum capacity of 300,000 barrels per day in 2011
with additional pump installations, some crude oil will be trucked from the field to the Guaduas
Station. At Guaduas, the crude is blended with naptha to reach a API gravity of 18.5 degrees
prior to entering another pipeline to Covenas. The tariff to deliver the 82 degree API gravity
naptha from the Cartagena sea port to Guaduas is $11.55 per barrel, and an additional $0.33
per barrel is charged for the blending process. The crude oil that enters the field pipeline to
Covenas for export is blended with naptha in the Rubiales field to reach the API gravity of 18.5
degrees. The delivery charge for the naptha from the Cartagena sea port to the field is $9.80
per barrel, and there is no blending charge there. The naptha tariff and blending costs are
summarized in Table 9.4.
The crude oil and blended oil/naptha mix incur tariff charges also. Meta is charged $10.73 per
barrel for crude that is trucked to Guaduas. After blending there, the oil/naptha mix is pumped
into a pipeline that charges a tariff of $2.03 per barrel to deliver the mix to Covenas for export.
The blended oil/naptha mix that leaves the Rubiales field in the new pipeline directly to Covenas
for export is charged a tariff that is coupled with throughput volume as follows:
Daily Volume from Rubiales Field Tariff Charge
100,000 to 125,000 bbl per day $6.39 per barrel
125,000 to 150,000 bbl per day $5.57 per barrel
150,000 to 175,000 bbl per day $6.55 per barrel
Over 175,000 bbl per day $6.30 per barrel
RPS Reserves Certification Report
R01002 29 February 2010
The crude oil and oil/naptha mix tariffs and blending costs are summarized in Table 9.4. The
average unescalated cost for tariffs and blending of produced crude oil and purchased naptha is
$8.07 per barrel over the life of the project.
Although the cost per barrel to truck the crude from the field is expected to decrease as the
pipeline capacity increases from 2010 to 2011 when the trucking is ended, the decline in cost
was not modeled in the economics as it is not significant relative to the overall analysis results.
Expenses - Abandonment and Reclamation
Production forecasts indicate that the majority of the wells would produce to at least June 30,
2016. The concession contracts do not require that Meta abandon inactive wells unless the
wells have been junked for mechanical reasons. Based on past experience, Meta has
forecasted that 2.5 percent of the wells in the field would need to be abandoned on an annual
basis at a cost of $300,000 each. The annual cost for this work has been included in the RPS
forecasts of field operating cost and is shown in Table 9.4.
9.5 Evaluation Parameters
The revenue and costs were input by concession so that the appropriate working and net
revenue interest cash flows could be calculated separately. The analysis was made for both
before tax and after tax cases. A two percent escalation was applied to the investment and
operating costs based on actual Columbian data and the global RPS oilfield forecast.
A 33 percent income tax was used in the after tax analysis. A tax credit for investments was
also used in which 40 percent of the total net investment for 2009 was deducted in 2010, and 30
percent of the total net investment in 2010 and 2011 was deducted in 2011 and 2012,
respectively. The tax credit was allocated by concession and reserves volume by category. No
tax credit was assigned to the proved producing reserves in 2011 and 2012 because those
volumes that were developed in prior years did not require future investments to produce to
depletion.
RPS Reserves Certification Report
R01002 30 February 2010
The annual cash flow profit was then discounted to present worth using a 10 percent discount
rate, and summed to calculate the cumulative discounted cash flow by concession and reserves
category. All dollars mentioned in the report are in U. S. currency.
9.6 Analysis Results
The PHDWIN economic model was used to perform the economic calculations. Tables 1.1
through 1.8 contain the summary level results. Output from these runs is included by
concession for each reserves category in Appendix 2 (before tax cash flows) and Appendix 3
(after tax cash flows).
Note: Due to the inclusion of naptha diluent in the sales volumes, and "hardwired" program
output formats of the PHDWIN software, the summary outputs and column labels do not match
other reporting tables in this report. The following glossary should be used in interpreting the
PHDWIN cash flow output tables:
"PHDWIN Column Label" = Meaning for this report
"Gross Oil" = Total field oil production (ie gross field reserves) plus Naptha diluent less oil
shrinkage
"Net Oil" = Meta Working Interest share of Net Reserves = Meta share of [total oil reserves plus
Naptha diluent less oil shrinkage less Royalty]
"Oil Revenue" = Meta Working Interest Net (after royalty) revenue
" Well Count" = Number of PHDWIN cases included in analysis
"Net Investment" (on the before tax report) = Meta Working Interest share of Development Costs
"Net Investment" (on the after tax report) = Meta Working Interest share of Development Costs
minus Capital investment tax credits
"Net Lease Costs" (on the before tax report) and "Net Op Costs" (on the after tax report) = Meta
Working Interest share of Operating Costs (including annual abandonment costs)
"Federal Income Tax" = Meta Working Interest Federal Income tax before application of Capital
Investment tax credits

10.0 QUALIFICATIONS AND LIMITATIONS
10.1 Independence and Conflict of Interest
This report has been prepared by RPS. RPS is an international independent oil and gas
advisory firm with Energy Division offices in the USA, UK, Canada, Singapore, Australia and the
Netherlands. This report was prepared in the RPS office located in Houston, Texas. All
evaluations performed by RPS are strictly fee-based and RPS has not and will not receive any
benefit, which may be regarded as affecting its ability to render an unbiased opinion.
10.2 Purpose, Scope and Use of This Report
This report was commissioned by Mr. Ysidro Araujo of Meta to evaluate the Rubiales Field. The
scope of the project was restricted to this brief. This report was prepared exclusively for the use
of the stated parties and should not be duplicated or distributed to any third parties without the
express written consent of RPS, except as required by law.
10.3 Available Data
This study was based on data supplied by Meta and on nonproprietary data from in-house files.
The supplied data was reviewed for reasonableness from a technical perspective. As is
common in oil field situations, basic physical measurements taken over time cannot be verified
independently in retrospect. As such, beyond the application of normal professional judgment,
such data must be accepted as representative. While we are not aware of any falsification of
records or data pertinent to the results of this study, RPS does not warrant the accuracy of the
data and accepts no liability for any losses from actions based upon reliance on data, which is
subsequently shown to be falsified or erroneous.
10.4 Professional Qualifications
RPS personnel who prepared this report are degreed professionals with the appropriate
qualifications and experience to complete the project brief. RPS and its staff do not claim
expertise in accounting, legal and environmental matters, and opinions on such matters do not
form part of this report.
RPS Reserves Certification Report
R01002 33 February 2010
10.5 Site Visit and Inspection
A site visit to the Rubiales field and Meta‟s technical office in Bogota was conducted by three
RPS personnel directly involved in the preparation of the report on December 14 and 15, 2009.
The ongoing development activity was observed, including drilling operations, production
facilities, water disposal facilities, and numerous construction projects that are in progress.
Pipelines, in-field gathering lines and the road system and living areas for staff and construction
crews were also observed. Every day, a personnel contingent of 5,800 people works in the field.
This requires a major coordination effort for personnel and materials that are brought in for the
field operations and construction projects. The work is conducted in a manner that respects the
native population as well as the environmental concerns of the government. RPS is not in a
position to comment on whether the operations are in compliance with any regulations that may
apply to them.
10.6 Liability Waiver
This report has been prepared on a best efforts basis to address the requirement of the brief
specified by the clients. The results and conclusions represent informed professional judgments
based on the data available and time frame allowed to perform this work. No warranty is implied
or expressed that actual results will conform to these estimates. RPS accepts no liability for
actions or losses derived from reliance on this report or the data on which it was based.

Recoverable Resources Classes and Sub-Classes
Class/Sub-Class Definition Guidelines
Reserves Reserves are those quantities of petroleum anticipated to be commercially recoverable by application of development projects to known accumulations from a given date forward under defined conditions.
Reserves must satisfy four criteria: they must be discovered, recoverable, commercial, and remaining based on the development project(s) applied. Reserves are further subdivided in accordance with the level of certainty associated with the estimates and may be sub-classified based on project maturity and/or characterized by their development and production status.
To be included in the Reserves class, a project must be sufficiently defined to establish its commercial viability. There must be a reasonable expectation that all required internal and external approvals will be forthcoming, and there is evidence of firm intention to proceed with development within a reasonable time frame.
A reasonable time frame for the initiation of development depends on the specific circumstances and varies according to the scope of the project. While 5 years is recommended as a benchmark, a longer time frame could be applied where, for example, development of economic projects are deferred at the option of the producer for, among other things, market-related reasons, or to meet contractual or strategic objectives. In all cases, the justification for classification as Reserves should be clearly documented.
To be included in the Reserves class, there must be a high confidence in the commercial producibility of the reservoir as supported by actual production or formation tests. In certain cases, Reserves may be assigned on the basis of well logs and/or core analysis that indicate that the subject reservoir is hydrocarbon-bearing and is analogous to reservoirs in the same area that are producing or have demonstrated the ability to produce on formation tests.
On Production The development project is
currently producing and selling petroleum to market.
The key criterion is that the project is receiving income from sales, rather than the approved development project necessarily being complete. This is the point at which the project “chance of commerciality” can be said to be 100%. The project “decision gate” is the decision to initiate commercial production from the project.
Approved for Development
All necessary approvals have been obtained, capital funds have been committed, and implementation of the development project is under way.
At this point, it must be certain that the development project is going ahead. The project must not be subject to any contingencies such as outstanding regulatory approvals or sales contracts. Forecast capital expenditures should be included in the reporting entity’s current or following year’s approved budget. The project “decision gate” is the decision to start investing capital in the construction of production facilities and/or drilling development wells.
Class/Sub-Class Definition Guidelines Justified for Development
Implementation of the development project is justified on the basis of reasonable forecast commercial conditions at the time of reporting, and there are reasonable expectations that all necessary approvals/contracts will be obtained.
In order to move to this level of project maturity, and hence have reserves associated with it, the development project must be commercially viable at the time of reporting, based on the reporting entity’s assumptions of future prices, costs, etc. (“forecast case”) and the specific circumstances of the project. Evidence of a firm intention to proceed with development within a reasonable time frame will be sufficient to demonstrate commerciality. There should be a development plan in sufficient detail to support the assessment of commerciality and a reasonable expectation that any regulatory approvals or sales contracts required prior to project implementation will be forthcoming. Other than such approvals/contracts, there should be no known contingencies that could preclude the development from proceeding within a reasonable timeframe (see Reserves class). The project “decision gate” is the decision by the reporting entity and its partners, if any, that the project has reached a level of technical and commercial maturity sufficient to justify proceeding with development at that point in time.
Contingent Resources
Those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations by application of development projects, but which are not currently considered to be commercially recoverable due to one or more contingencies.
Contingent Resources may include, for example, projects for which there are currently no viable markets, or where commercial recovery is dependent on technology under development, or where evaluation of the accumulation is insufficient to clearly assess commerciality. Contingent Resources are further categorized in accordance with the level of certainty associated with the estimates and may be sub-classified based on project maturity and/or characterized by their economic status.
Development Pending
A discovered accumulation where project activities are ongoing to justify commercial development in the foreseeable future.
The project is seen to have reasonable potential for eventual commercial development, to the extent that further data acquisition (e.g. drilling, seismic data) and/or evaluations are currently ongoing with a view to confirming that the project is commercially viable and providing the basis for selection of an appropriate development plan. The critical contingencies have been identified and are reasonably expected to be resolved within a reasonable time frame. Note that disappointing appraisal/evaluation results could lead to a re-classification of the project to “On Hold” or “Not Viable” status.
The project “decision gate” is the decision to undertake further data acquisition and/or studies designed to move the project to a level of technical and commercial maturity at which a decision can be made to proceed with development and production.
Class/Sub-Class Definition Guidelines Development Unclarified or on Hold
A discovered accumulation where project activities are on hold and/or where justification as a commercial development may be subject to significant delay.
The project is seen to have potential for eventual commercial development, but further appraisal/evaluation activities are on hold pending the removal of significant contingencies external to the project, or substantial further appraisal/evaluation activities are required to clarify the potential for eventual commercial development. Development may be subject to a significant time delay. Note that a change in circumstances, such that there is no longer a reasonable expectation that a critical contingency can be removed in the foreseeable future, for example, could lead to a re-classification of the project to “Not Viable” status.
The project “decision gate” is the decision to either proceed with additional evaluation designed to clarify the potential for eventual commercial development or to temporarily suspend or delay further activities pending resolution of external contingencies.
Development Not Viable
A discovered accumulation for which there are no current plans to develop or to acquire additional data at the time due to limited production potential.
The project is not seen to have potential for eventual commercial development at the time of reporting, but the theoretically recoverable quantities are recorded so that the potential opportunity will be recognized in the event of a major change in technology or commercial conditions.
The project “decision gate” is the decision not to undertake any further data acquisition or studies on the project for the foreseeable future.
Prospective Resources
Those quantities of petroleum which are estimated, as of a given date, to be potentially recoverable from undiscovered accumulations.
Potential accumulations are evaluated according to their chance of discovery and, assuming a discovery, the estimated quantities that would be recoverable under defined development projects. It is recognized that the development programs will be of significantly less detail and depend more heavily on analog developments in the earlier phases of exploration.
Prospect A project associated with a potential accumulation that is sufficiently well defined to represent a viable drilling target.
Project activities are focused on assessing the chance of discovery and, assuming discovery, the range of potential recoverable quantities under a commercial development program.
Lead A project associated with a potential accumulation that is currently poorly defined and requires more data acquisition and/or evaluation in order to be classified as a prospect.
Project activities are focused on acquiring additional data and/or undertaking further evaluation designed to confirm whether or not the lead can be matured into a prospect. Such evaluation includes the assessment of the chance of discovery and, assuming discovery, the range of potential recovery under feasible development scenarios.
Play A project associated with a prospective trend of potential prospects, but which requires more data acquisition and/or evaluation in order to define specific leads or prospects.
Project activities are focused on acquiring additional data and/or undertaking further evaluation designed to define specific leads or prospects for more detailed analysis of their chance of discovery and, assuming discovery, the range of potential recovery under hypothetical development scenarios.
Reserves Status Definitions and Guidelines
Status Definition Guidelines
Developed Reserves
Developed Reserves are expected quantities to be recovered from existing wells and facilities.
Reserves are considered developed only after the necessary equipment has been installed, or when the costs to do so are relatively minor compared to the cost of a well. Where required facilities become unavailable, it may be necessary to reclassify Developed Reserves as Undeveloped. Developed Reserves may be further sub-classified as Producing or Non-Producing.
Developed Producing Reserves
Developed Producing Reserves are expected to be recovered from completion intervals that are open and producing at the time of the estimate.
Improved recovery reserves are considered producing only after the improved recovery project is in operation.
Developed Non-Producing Reserves
Developed Non-Producing Reserves include shut-in and behind-pipe Reserves.
Shut-in Reserves are expected to be recovered from (1) completion intervals which are open at the time of the estimate but which have not yet started producing, (2) wells which were shut-in for market conditions or pipeline connections, or (3) wells not capable of production for mechanical reasons. Behind-pipe Reserves are expected to be recovered from zones in existing wells which will require additional completion work or future re-completion prior to start of production. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well.
Undeveloped Reserves
Undeveloped Reserves are quantities expected to be recovered through future investments:
(1) from new wells on undrilled acreage in known accumulations, (2) from deepening existing wells to a different (but known) reservoir, (3) from infill wells that will increase recovery, or (4) where a relatively large expenditure (e.g. when compared to the cost of drilling a new well) is required to (a) recomplete an existing well or (b) install production or transportation facilities for primary or improved recovery projects.
Reserves Category Definitions and Guidelines
Category Definition Guidelines
Proved Reserves
Proved Reserves are those quantities of petroleum, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations.
If deterministic methods are used, the term reasonable certainty is intended to express a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate. The area of the reservoir considered as Proved includes (1) the area delineated by drilling and defined by fluid contacts, if any, and (2) adjacent undrilled portions of the reservoir that can reasonably be judged as continuous with it and commercially productive on the basis of available geoscience and engineering data. In the absence of data on fluid contacts, Proved quantities in a reservoir are limited by the lowest known hydrocarbon (LKH) as seen in a well penetration unless otherwise indicated by definitive geoscience, engineering, or performance data. Such definitive information may include pressure gradient analysis and seismic indicators. Seismic data alone may not be sufficient to define fluid contacts for Proved reserves (see “2001 Supplemental Guidelines,” Chapter 8). Reserves in undeveloped locations may be classified as Proved provided that: • The locations are in undrilled areas of the reservoir that can be
judged with reasonable certainty to be commercially productive.
• Interpretations of available geoscience and engineering data indicate with reasonable certainty that the objective formation is laterally continuous with drilled Proved locations.
For Proved Reserves, the recovery efficiency applied to these reservoirs should be defined based on a range of possibilities supported by analogs and sound engineering judgment considering the characteristics of the Proved area and the applied development program.
Probable Reserves
Probable Reserves are those additional Reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves.
It is equally likely that actual remaining quantities recovered will be greater than or less than the sum of the estimated Proved plus Probable Reserves (2P). In this context, when probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered will equal or exceed the 2P estimate.
Probable Reserves may be assigned to areas of a reservoir adjacent to Proved where data control or interpretations of available data are less certain. The interpreted reservoir continuity may not meet the reasonable certainty criteria.
Probable estimates also include incremental recoveries associated with project recovery efficiencies beyond that assumed for Proved.
Category Definition Guidelines
Possible Reserves
Possible Reserves are those additional reserves which analysis of geoscience and engineering data indicate are less likely to be recoverable than Probable Reserves.
The total quantities ultimately recovered from the project have a low probability to exceed the sum of Proved plus Probable plus Possible (3P), which is equivalent to the high estimate scenario. When probabilistic methods are used, there should be at least a 10% probability that the actual quantities recovered will equal or exceed the 3P estimate. Possible Reserves may be assigned to areas of a reservoir adjacent to Probable where data control and interpretations of available data are progressively less certain. Frequently, this may be in areas where geoscience and engineering data are unable to clearly define the area and vertical reservoir limits of commercial production from the reservoir by a defined project.
Possible estimates also include incremental quantities associated with project recovery efficiencies beyond that assumed for Probable.
Probable and Possible Reserves
(See above for separate criteria for Probable Reserves and Possible Reserves.)
The 2P and 3P estimates may be based on reasonable alternative technical and commercial interpretations within the reservoir and/or subject project that are clearly documented, including comparisons to results in successful similar projects. In conventional accumulations, Probable and/or Possible Reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir within the same accumulation that may be separated from Proved areas by minor faulting or other geological discontinuities and have not been penetrated by a wellbore but are interpreted to be in communication with the known (Proved) reservoir. Probable or Possible Reserves may be assigned to areas that are structurally higher than the Proved area. Possible (and in some cases, Probable) Reserves may be assigned to areas that are structurally lower than the adjacent Proved or 2P area. Caution should be exercised in assigning Reserves to adjacent reservoirs isolated by major, potentially sealing, faults until this reservoir is penetrated and evaluated as commercially productive. Justification for assigning Reserves in such cases should be clearly documented. Reserves should not be assigned to areas that are clearly separated from a known accumulation by non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results); such areas may contain Prospective Resources. In conventional accumulations, where drilling has defined a highest known oil (HKO) elevation and there exists the potential for an associated gas cap, Proved oil Reserves should only be assigned in the structurally higher portions of the reservoir if there is reasonable certainty that such portions are initially above bubble point pressure based on documented engineering analyses. Reservoir portions that do not meet this certainty may be assigned as Probable and Possible oil and/or gas based on reservoir fluid properties and pressure gradient interpretations.
