Why Build A 3D Reservoir Model?
3D Reservoir Modelling Workflow
(After Roxar RMS)
• 3D Detailed Geologic Static Model– Understanding the resource in place– Understanding the play type– Well targeting
• Upscaled Flow Simulation Model– Performance prediction in the
absence of dynamic data– Starting point for a history match
when dynamic data is available– Prediction of reserves per well– Prediction of new processes in an
existing field

RESCUE Consortium – 1 / 3
• Initiated in 1995, RESCUE is a Joint Industry Project managed by Energistics (formerly POSC). The acronym 'RESCUE' stands for REServoir Characterization Using Epicentre– http://www.posc.org/rescue
• The purpose was to provide aforum for the development ofan open standard for thetransfer of data from“geomodels to upscalers”, specifically through the use of the POSC Epicenter data model

RESCUE Consortium – 2 / 3
• Delivery of the standard replaced Epicenter with a collection of binary flat files to describe:– Structural Framework: Faults & Horizons– 3D Grids: Static and Simulation– Wells: Especially Log Data
• To ensure a commonimplementation a set ofClass Libraries weredeveloped under contractto the RESCUE project,and are the vehicle of choice for implementing an API to the RESCUE standard.

RESCUE Consortium – 3 / 3
• RESCUE Organization– Mike Castleberg, Program Manager– Rod Hanks, Class Libraries– Oil Company Chair
• Oil Company Sponsors– Shell, BP, Total, StatoilHydro
• Vendors– 20+ Current Members delivering commercial
applications with RESCUE readers &/or writers
• ILAB’s “Interactive Laboratories”– Multi-vendor testing and development– Oil company guidance– Genuine collaboration

RESCUE in the WorkflowInitial Scope: Static to Dynamic
3D Reservoir Modelling Workflow
(After Roxar RMS)
• RESCUE– 3D Grid is the primary data– Faults / Horizons / Wells
associated with the grid• Provides a link from Geologic to
Simulation Vendors• Workflow has been extended to
support better multi-vendor reservoir characterization
RESCUE provides for the transfer of the 3D Reservoir Model from the “Static” to the “Dynamic” Domain
6th April 2009 | 11Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESCUE in Use
• Deepwater GOM Appraisal– Large Structure– Partially Subsalt– Structurally Complex– Potentially Complex
Channel Architecture– Faults & Fault Seal?– Connected Volumes?– Reserves per Well?– Performance Prediction?
• RESCUE used to combine multiple analyses since no one application could provide adequate technical assessment – Partial updates can be managed in RESCUE now, but it
takes user skill and specific application experience

RESQML™ Roadmap
• RESCUE v37 remains the standard in production use until RESQML™ enabled applications render it obsolete

SIG and are making good progress towards an XML-based standard based on relatively simple models
• 2009: Version 1.0– By year end, first standard published for vendor comment
& prototype implementation
• 2010: Version 1.N– Revisions of 1.0 plus new features
• 2010/11: Version 2.0– First release in commercial vendor tools
6th April 2009 | 18Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Roadmap - Structural
• Version 1.0– Faults and Horizons transferred as individual
objects
• Version 2.0– Faults and Horizons in a Structural Framework– Rich set of representations, e.g., tri-surfaces, 2d
grids, scattered data, etc.– Discretized faults,
horizon & structureon the GRID
• Version 3.0– Multiple realizations– Enhanced metadata– Rule based (?)
6th April 2009 | 19Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Roadmap - GRID
• Version 1.0– Single / Multiple Corner Point Grids– Numerical Local Grid Refinement– Straight / Piecewise Linear / Spline Coordinate Lines– Multiple layering schemes– Static and Dynamic cell properties, with packing– Non-Standard Adjacency (Pinch-out & Faults)
• Version 2.0– Geometric Local Grid Refinement & Coarsening– Seismic Volumes / Tartan Simulation Grids– Node based properties (geomechanics & seismic)
• Version 3.0– Radial Grids– Streamline-based unstructured grids– Unstructured Cell Indexing and Truncated Grids– 2.5D and 3D PEBI Grids

RESQML™ Requirements – 1a / 5
• What Have We Learned from RESCUE?– Work processes, not a single “Static to Dynamic”
Workflow– Also “Static to Static” and “Dynamic to Static” transfers
• Support for partial model transfers & updates– Structural description in Application-1– Properties in Application-2– Well design in Application-3– Upscaling in Application-4– Dynamic Predictions in Application-5
• Transfer predictions back to the static model– Review Performance Against Predictions in Application-6
• Update description back in Applications-1,2,…
6th April 2009 | 25Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Requirements – 1b / 5
• Partial updates can be managed in RESCUE now, but it takes user skill and specific application experience
• Deepwater GOM Appraisal– Large Structure– Partially Subsalt– Structurally Complex– Potentially Complex
Channel Architecture– Faults & Fault Seal?– Connected Volumes?– Reserves per Well?– Performance Prediction?
• RESCUE used to combine multiple analyses since no one application could provide adequate technical assessment
6th April 2009 | 26Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Requirements – 2 / 5
• Commercial Requirements are More Rigorous– Sarbanes-Oxley has increased the rigor which we
must document reserves, with supporting data & interpretations
– “7 Years + Life of Field” has increased the need for Vendor & Application neutral data formats
– The use of Markup Languageallows RESQML™ to representsignificantly more metadata oninterpretations and data sourcesthan does RESCUE.
6th April 2009 | 27Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Requirements – 3 / 5
• Managing Risk and Uncertainly– Markup language provides extensions to our
current data structures to support multiple reservoir models
– Examples:• Here is a collection of 10 equi-likely reservoir models• Here is a most-likely and a standard distribution “Top
Reservoir” map which honors all of our well data.– Please create 100 equi-likely Top Reservoir maps
– Extensions:• Representation by Value• Representation by a Collection• Representation by a Rule
6th April 2009 | 28Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Requirements – 4 / 5
• Giga-cell Models– Successful continued infill development of
mature producing reservoirs requires more detail, higher resolution, and better Static Dynamic integration
– Example: SPE 116675• “From Mega-Cell to Giga-Cell Reservoir Simulation”
Ali Dogru et.al., Saudi Arabian Oil Company• 109 cell dynamic simulation models• 1010-1011 cell static geologic models
– RESCUE interchange formats have not been optimized for systems of this size
• 107-108 cell static geologic models are common
6th April 2009 | 29Energistics Standards Seminar / SPE Digital Energy Conference 2009 |
RESQML™ Requirements – 5 / 5
• Additional Classes of Models– 4D Seismic exceptionally useful for
reservoir surveillance and management– Geomechanical models extend from the
surface to beyond the reservoir– Seismic Volumes– Tartan Simulation Grids
• Unstructured Grids– Streamline simulation models are based
on 1D streamlines embedded in a 3D space– Unstructured Cell Indexing and Truncated Grids are in
current use by several 3D Static modeling applications to describe complex structures, especially reverse faults
– 2.5D and 3D PEBI grids are in use in the Simulation Domain
