1.0 PREAMBLE

Oil India Limited being an E&P Public Sector company of India, with its rich legacy, it

bears moral and corporate responsibility to contribute it’s best for strengthening

country’s energy security and hence the organization has its primary objective to

continuously endeavor for accretion of reserves and maintenance of production level. This

calls for drilling in logistically difficult and geologically complex boundary conditions.

Drilling Department is fully committed to achieve the organizational goals and the whole

work-force is relentlessly engaged as a team with dedication in carrying out the following

operations/ tasks to fulfill the targeted objective.

i. Drilling and completion of Exploratory & Development wells

ii. Drilling of infill and Water Disposal wells.

iii. Carrying out work-over/well servicing operations.

iv. Technical Services to support all the above operations.

v. To commensurate the successful completion of all the Drilling and Workover

(partly), Cementing services were carried out mostly through in-house resources

having only one hired support services.

vi. All administrative function in support of above operations & services which are to

be managed on 24X7 basis in spite of manpower constraints.

vii. First hand public relation function, Health, Safety & Environment function is

performed by field executives.

The challenges range from drilling shallow wells to deep Eocene wells, sub normal

to abnormally (high) pressure & temperature wells, development of ranked wildcat wells,

wells having straight, directional & horizontal trajectories are drilled having high

displacement profile. Servicing and enlivening of production wells of varied nature &

complicacies are also another challenge which is worth mentioning.

To carry out its drilling activities in the development and exploratory fields of

Assam & Arunachal Pradesh, Drilling Department utilized twelve (12) in-house drilling

2016-17

rigs of varying capacities – six (06) 1400 HP, three (03) 2000 HP and one (01) each of 750

HP, 600 HP (for WDW) and 3000 HP. In addition to in-house fleet, Five (05) No of Charter-

Hire Drilling Rigs (03 No 1400 HP & 02 No. 2000HP) were also utilized for drilling

activities in Assam.

Drilling activity in the year 2016-17 was increased to achieve 1,59,987 M (51 nos

completed well) of drilling meterage compared to 1,38,339 M in the year 2015-16, which

is approximately 15.6 % higher than previous year. This achievement is the all time

highest in the history of OIL.

214 Work over jobs were completed against target of 200 jobs resulting achievement

of 107 % which is also all time highest achievement in the history of OIL.

It is also worth mentioning that adherence and compliance of more and more

stringent Safety & Environmental regulations and policies by statutory bodies like DGMS,

OISD, and APCB & CPCB were also remained a major challenge with limited supervisory

staff. All out efforts were being made for full compliance of the statutory regulations and

to ensure safety of men & machines.

Note:

Major problems being faced in enhancing the target achievement of Drilling & Work over

operations are mainly attributable to acquisition of land, preparation of plinth during

rainy season and environmental issues which has direct impact on timely availability of

locations for the rigs. During the year under review, a total of around 0.82 Rig Year losses

have been recorded for the said reasons. It is expected that the proposed J-bend &

Extended reach directional drilling will partially curb the above issues.

3.0 RECORDABLE & SIGNIFICANT ACHIEVEMENTS

The total meterage 1,59,987 m. is the highest meterage achieved in the history of

OIL.

Total 214 no of Work over jobs completed for the year which is all time record for

OIL

Total numbers of 286 cementation jobs were carried out during the FY which is all

time highest. This comprises of 154 Primary jobs which is also highest and 132

secondary jobs.

Cement consumed is all time highest due to more numbers of 4 stage wells.

Installation and commissioning of 02 nos VFD rigs were successfully carried out.

A total of 09 numbers of 3512B DITA Caterpillar Power Packs have been procured

and commissioned in Rigs S#6 & S#8.These power packs have Acoustic Enclosure conforming to the latest sound level standards & extended exhaust stack height

which meets the guidelines prescribed by CPCB.

In order to comply with the latest emission norms and noise levels as prescribed by

CPCB, 06 (SIX) nos. of acoustic enclosures were procured for the CAT 3512A DITA

engines and same were commissioned in Rig S#1,S#2 & S#3 rigs.

Commissioning of 4 nos. of work over Rigs & one no drilling rig with solid control &

tank system for water disposal well procured against P.O. no.7950934 was

completed

At Loc: BGR, Maximum Horizontal Displacement of 2094m was achieved with TVD

of 3900 m. For this well, the deviation section designed the optimum well profile for

all the sections considering probable torque and drag issues.

Loc:MKB-1 was completed with 5 stage Casing policy ( two liners 7” and 5” with 7”

tie-back). It is the deepest well (5624m MD/ 5607m TVD) producing @ 70KLPD in

the history of OIL and the first planned 6” hole section with 5” liner completion.

2016-17

4.0 MAJOR REASONS FOR REDUCTION IN DRILLING METERAGE

It may be noted that there has been considerable constraints in following areas which

resulted in reduced drilling meterage

A. Non-readiness of forward Locations & waiting for the same:

Total Loss of Days: 164 Days

Loss of Planned Rig Year: 0.45

Total Loss of Meterage: 4927 m

B. Critical Down Hole Problems (SUB SURFACE PROBLEM):




C. Rig-Repair (SURFACE PROBLEM):



Total Loss of Meter age: 2944 m

D. Production Testing exceeding planned days (Extended PRODUCTION TESTING):




E. Environmental Problems: (Local problem. Bandh, Strike, blockade etc):





12

2016-17

F. Miscellaneous Problems (Contract/Contractor related problems/other problems not

covered by above reasons)




H. Exploring in deeper horizon and due to logistic & environmental problem hampered

achievement of target meterage.

Note:

1. 178724 m drilling planned with 16.30 Rig Year for 2016-17. Hence, prorated per

days loss has been considered to be 30.04 M per day.

2. Thus a loss Of 30461 M has thus been recorded due to the above reasons for the

1) Rig selection as per well requirement/programme.

2) Continuous persuasion for the progress of the supporting departments.

3) Reduction of time by proper well operation programme.

4) Close mentoring & frequent field visits by senior officials.

System Development for improvement:

1) Field application of high-tech communication.

2) Workover operation planning (Well wise /Job wise) prior to execution.

3) SOPs & Check list development and upgradation.

4) Continuous knowledge sharing (“Knowledge Management” initiative)

5) Periodic onsite & offsite operation training to Officers & Work persons

2016-17

6.0 DEVIATION SECTION

Land acquisition problem became more and more severe over the years. During the last

financial year, except water disposal wells, all the wells were directional wells i.e. in other

word 100% wells were deviated.

Moreover, few wells were of very high displacement (horizontal drift >1600-to-1930mts)

with TVD>3800mts. These wells were really very challenging.

The Deviation section of Drilling Department, with its very limited manpower strength, is

directly associated with vast jobs of planning and designing of Directional wells along

with supervising execution during actual drilling operation. Deviation section endeavored

to meet the geological targets and supervised the drilling operation with the help of hired

directional services.

This section plan & design the optimum well profile for minimum torque, drag, anti-

collision and hydraulics issues as per the surface and sub surface co-ordinates given in

the draft Geological DDDP ( Depth Data Drilling Policy) prior to finalization of the

DDDP for a particular location.

Whenever directional service provider declines to accept a well profile due to torque, drag

or anti-collision issues, this section takes up the responsibility and assists the service

provider for drilling by providing look ahead correction plan with a new BHA and

hydraulics.

Hence the responsibility lies on this section to approve the drillability of the well.

During 2016-17 this section had taken up:

1. OIL achieved a record drilling meterage of 1,59,987 m during the year. Out of this

1,25,201m drilling meterage i.e. around 78.21% of the total meterage was achieved

from directional drilling where the section contributed in designing drilling

parameters along with BHA and supervising the directional drilling operations with

the help of directional service providers.

3.1. New Contract framework during the year 2016-17:

A. To avoid waiting period for directional drilling service, 4(four) numbers of limited

directional drilling contracts were formulated in a very short span of time in this

financial year. Same were being floated and 3 numbers of contracts

(CDG0778/DRLG/2016,CDG2565/DRLG/2016,OIL/6208211/DRLG/2017)

have already been awarded to Service provider and for the fourth tender

2016-17

4.0. Special Job Done during 2016-17:

4.1. Loc. TU:

Completed OIL’s benchmarking well for achieving highest ever THD of 1942m at TVD

3982m in record time. (1st time in NE India)

4.2. Loc.BGR:

Maximum Horizontal Displacement of 2094m was achieved with TVD of 3900m at Loc:

BGR. For this well, the deviation section designed the optimum well profile for all the

sections, with due consideration of probable torque and drag issues and also designed

the drill string considering abnormal surface torque.

It is to be noted here that, directional service provider M/s Schlumberger had declined to

drill the 8. ½” section due to expected surface torque of 28 Klb-fts (M/up torque of S

grade D/P).However, this section took the challenge to complete the well by designing the

BHA and hydraulics to keep the T&D within the permissible limit and was successful to

drill up to the target depth achieving highest ever displacement in OIL’s history of drilling

directional well of such high range of horizontal displacement.


26

2016-17

4.3. Loc:MKB-1( Mechaki-5):

Well Mechaki-4 (Loc. MKB) was drilled as a vertical hole during the year 2014 and due to

various down hole problems, B, C & D-holes were drilled but could not be completed

successfully. Finally the said well had to be abandoned in the year 2015 due to severe

down hole problems.

Subsequently, Loc: MKB-1 was proposed to be drilled as a substitute for Loc.MKB well

from the existing plinth of Loc. MKB in 2016-17 to probe the up-dip extent of the

hydrocarbon bearing reservoirs within Paleocene/Eocene formations of the West Mechaki

structure.

Extensive planning and analysis was done by this section based on the last well’s history

and came up with 5 stage Casing policy ( two liners 7” and 5” with 7” tie-back) as a

solution. This helped to isolate the pressure variance zones (Fig-1). It is the deepest

(5624m MD/ 5607m TVD) producing from this directional well @ 70KLPD in the history

of OIL and the first planned 6” hole section with 5” liner completion. The well was

completed with scientifically designed in-house drilling fluid. This prestigious well of OIL

was drilled and completed successfully overcoming all down hole problems before

planned days. To address the bit walking issue, which was experienced in last location

due to formation dip and to ensure verticality of the hole, it was planned and engaged

directional drilling service from 17 ½” to 6” section hole section.

Figure-1


27

2016-17

4.4. Loc: MFK:

Loc.MFK was also planned with 5 stage casing to avoid casing overlap in primary target

above kopili shale as explained below:

4.5. Loc. HYS:

This is the first J-profile well designed by in-house deviation expert with hole inclination

above 40 degree to overcome the presence of fault as intimated by G&R department based

on seismic data interpretation. In-house directional team took extreme precaution while

drilling and completed the well successfully.

4.6. Loc: TAT:

This well was present in cluster plinth of Loc: TT, TAL, TAD. So while designing the

directional well profile of Loc: TAT as per geological note, found severe collision issue with

Loc: TT & TAL. So, well was designed to turn its trajectory in the opposite direction of

Loc: TT & TAL and realigned it in the desired direction with minimum dog leg severity.

Well trajectory becomes 3D J-profile for the first time in the history of OIL. Well was

drilled and completed without any down hole complexity with 4CP.


28

2016-17

4.7. Loc. DHL:

Loc: DHL was designed as J-bend well with KOP@1950m in 12.1/4” section with

maximum inclination of 19.34˚with a vertical section of 684m.Range of 12.1/4” section

was initially planned as (1970m-3400m). After completion of drilling the 17.1/2” hole

section and at the time of cementation of the 13.3/8″x68PPFxN80xBTC casing, the casing

string got disengaged at around 1870m during bumping of cement plug at 2500 PSI. The

string was matched on and annulus was cemented keeping shoe at 1951.18m (drilled

depth@1954m). While running in bit, got cement top @1166m; which was cleaned upto

1870m. However, no further progress observed beyond 1870m. Thereafter milling was

carried out with the help of number of tapered mills to the depth of 1872.35m, beyond

which no further milling was possible. Finally a cement plug was placed in the range of

1800m-1870m. The rig was released on 31-03-2016 and next cluster loc: DHK was

drilled. Meanwhile during drilling of Loc:DHK, a new contract was lined up for hiring of

expert service immediately for setting of whip-stock and window milling of 13.3/8” cased

hole at Loc:DHL so that rig idling time could be minimised. Consequently 13.3/8″ casing

scrapper trip was made up to cement top @1759m.Ran the whip stock assembly in

combination with the milling assembly consisting of lead mill, secondary mill and steering

mill. Scribed the entire string after orienting the face of the whip stock towards 126˚ TB

(S 54˚ E). Set the whip stock at the depth of 1751m and milling was done from 1738.5m

to 1747m and exited from the casing and drill a rat hole up to 1747.5m (0.5m

only).Subsequently, ran in bit to bottom and drilled a rat hole into the formation up to

the depth of 1750.50m.Thereafter pulling out of hole and ran in directional hook up

containing mud motor with 1.5˚ bend for further directional drilling upto TD and

completed the well successfully without any downhole anomalies. The well later started

producing @80KLPD.


29

2016-17

5.0. Cost saving measures during 2016-17:

Enhanced ROP was achieved by

o Limiting sliding mode to the maximum extent during drilling of tangent

section in directional wells.

o PDC bit was successfully used to the maximum extent to reduce the drilling

time.

o All S-bend wells in dropping stage from 8 degree angle are done by in-house

rotary BHA; saving considerable amount of company’s outgo to directional

drilling service.

Effective utilization of hired directional services saved substantial amount of well

cost.


30

2016-17

After expiry of drilling software consultant tenure from March’15, this section

managed and handled directional software on its own and delivered the quality

service to its stake holder and saved around 2,67,57,000.00 INR up to 31/03/2017

in terms of company’s financial outgo for engaging outside expert/consultant.

Without using North seeking Gyro tool for setting whip-stock at Loc: DHL and

scribed the entire string after orienting the face of the whip-stock towards desired

direction successfully, considerable amount to the tune of around INR

57,64,379.00 was saved.

Exclusive contribution of the section to the company:

i) This refers mainly to the land acquisition problem. Many directional wells were

drilled from existing plinth saving a huge amount against land procurement.

ii) Due to the success of the high displacement and high angle J-Bend wells,

targets once in-accessible, are now explored to hit those geological targets which

helped OIL to enhance the existing production.

6.0. Manpower position:

This section is headed by DGM-Drilling (Deviation), with 02 (Two) numbers of Executives

in Level-1, who are responsible for carrying out in house directional ( S-Profile) wells,

side tracking operations and also assist in monitoring the directional contracts under the

service providers.

at the work-over locations. A considerable quantity of HSD has been saved by using

these 7nos Solar Gen Sets. The quantity of HSD saved is 2355 Litres amounting

Rs. 1,29,525.00 (considering average price of HSD @ Rs. 55.00 per litre).

E. Energy Conservation & Pollution Control Measures Adopted:-

1. The installed generating capacity of each new Solar Genset commissioned is 1.5

KW having 06 Nos. of 250 Wp Poly Crystalline PV panel mounted on the solar Gen

sets with an unique structure. The area illumination is done with 8 Nos. pole mounted

LED lights of 24Wp each. The total Renewable Energy generated till the end of the

FY 16-17 is 542.77 units.

2. All efforts were given for work-over operations and Production without Pollution. To

achieve this, system has been adopted in all Workover wells to collect the fluids

associated with crude oil production during testing of the wells in a closed covered tank

instead of disposing the same in the effluent pit.

We have also collected the burnt oil from engines & pumps during servicing job and put

into this tank. Used lube oil and fuel filters are buried under earth within the plinth to

avoid any further spillage.

We use Lube oil evacuating & dispensing pump unit to BHEL#A rig for evacuating burnt

lube oil from engine/pump & take utmost care to minimize pollution hazards.

53

2016-17

Conclusion:

With the increase in Drilling and Work-over activities over the last few years consequent

to the deployment of total 17 nos. of Drilling rigs (includes 1 rig for water well drilling

operations) and 24 Nos. of Work-over rigs there has been a manifold increase in our in-

house activities to cater for these additional rigs with the existing manpower.

It may be appreciated that besides the conventional day-to-day jobs, the need for carrying

out various on-line transactions for issuance or transfer of materials, maintenance &

testing of equipment, record-keeping, planning & monitoring, etc is increasing day-by-

day. Owing to increased deployment of our equipment to Charter Rigs the frequency of

maintenance jobs has also substantially increased. Stringent safety and testing norms

being the order of the day, has necessitated better and detailed record-keeping & status

monitoring for all the equipment.

This substantial increase in work volume has however not been offset by the requisite

increase in manpower allocation to the section. To add to its woes, the section has on the

contrary been handicapped due to superannuation of experienced personnel in the recent

past with an ageing and ever-depleting workforce. With the present manpower strength it

is proving to be a herculean task to deliver the quality of service that has come to be

expected of the section. A review of the manpower strength allocated to the section is the

need of the hour to enable us to continue providing quality service in the days ahead.

11. HEALTH, SAFETY AND ENVIRONMENT

Operational Excellence is a continuous and long-term strategy to improve Company’s

performance systematically. HSE criteria functions such as employee safety, process and

asset safety, product safety and environmental impacts are important considerations

when analyzing operational risks. Therefore HSE domain plays major role in the

improvement of operational excellence of a Company.

Keeping in view of the above, Drilling department is constantly working hard in complying

and improving its HSE aspects. Drilling department is committed for implementation of


54

2016-17

HSE regulations in its operations as well as improving its day to day HSE related

activities.
