RESCUE PROJECT

RESCUE PROJECT

• RESERVOIR CHARACTERIZATION USING EPICENTRE
• A JOINT INDUSTRY PROJECT TO DEFINE AND PROMOTE
  THE USE OF STANDARDS FOR DATA EXCHANGE AND
  INTEROPERABILITY
• MANAGED BY POSC

3
OBJECTIVESPhase 1

• A STANDARD REPRESENTATION OF THE 3D GEOLOGIC
  MODEL
• TO INCLUDE SURFACES AND PROPERTY DISTRIBUTIONS
• TO REPRESENT THE SAME EARTH MODELS IN DIFFERENT
  APPLICATIONS AND EXPORT THEM TO UPSCALERS

4
EXPECTED RESULTSPhase 1

• RECOMMENDATIONS FOR CHANGES TO EPICENTRE
• EPICENTRE COMPATIBLE EARTH MODEL AND UPSCALING
  SOFTWARE
• RESERVOIR PROPERTY GRIDS IN EPICENTRE FOR
  SIMULATION
• STANDARD INTERFACE TEMPLATES AND REUSABLE DATA
  ACCESS CODE

5
ACTIVITIESPhase 1

• SIX BUSINESS MEETINGS
• SEVEN MAPPING/MODELING SESSIONS
• EIGHT ILABs

6
SUCCESSESPhase 1

• Successfully generated and exchanged synthetic
  models with multiple block units and features
  such as internal, Y, and dying faults. (ILAB 1,
  2, 3a)
• Successfully modeled a part of the Gullfaks field
  and passed it to the upscalers. (ILAB 3b)

7
SUCCESSESPhase 1

• Tested class Libraries with a variety of real
  world models. (ILAB 4)
• Successfully stored geologic models into an
  Epicentre data store and retrieved them in the
  upscale applications. (ILAB 5)
• Demonstrated the modification of property grids
  and passed them back to the geologic models.
  (ILAB 5)

Phase 1 MODEL IMPLEMENTATION

• MOVED AWAY FROM DATA ENTITIES TOWARD APPLICATION
  SPECIFIC BUSINESS OBJECTS
• USED CLASS LIBRARIES AS AN API TO MANIPULATE THE
  BUSINESS OBJECTS

9
Phase 1 MODEL IMPLEMENTATION

• TWO STORAGE MODES
• DATA REPRESENTED IN FLAT FILES (BINARY or ASCII)
  Very fast, but only sequentially accessible and
  cannot be updated. Commercial software releases.
• EPICENTRE STORAGE BY DECOMPOSITION OF THE
  BUSINESS OBJECTS INTO PRIMITIVE DATA ENTITIES
  Slower (1000 times) and requires a modified
  version of the Epicentre V2.2 model. Not
  practical for commercial usage at this time.

10
DELIVERABLESPhase 1

• AN API FOR WRITING AND READING RESCUE MODELS
• Available for download through www.posc.org/rescue
  
• RESCUE COMPATIBLE APPLICATIONS FROM VENDOR
  PARTICIPANTS
• Commercial releases of software with RESCUE
  capability in 1998 and 1999. Future ability to
  move property data back to the geologic models to
  allow iteration of models and simulation time
  steps.

11
PHASE 2

• The role of the RESCUE project is to actively
  promote, encourage and facilitate RESCUE as an
  ongoing and evolving EP standard for the
  exchange of Geological Models
• Oil Company funding for administrative purposes
  only, with vendors paying their own way to
  meetings and activities.

12
MEMBERS/FUNDINGPhase 2

• It is expected that the majority of Phase 1
  members will be participants in Phase 2.
• New members are sought who can actively bring
  additional expertise, especially in other
  modelling techniques and standards.
• Oil Company funding is anticipated to be in the
  range of K15-20 per annum.

13
OBJECTIVESPhase 2

• Extend the data model to include other
  representations, such as triangulated surfaces.
• Extend the data model to better support
  collaborative work flow scenarios.
• Add data and model validation features to make
  the RESCUE data model more robust.

14
OBJECTIVESPhase2

• To incorporate the developing RESCUE data model
  into commercial product.
• To provide an ongoing forum for the discussion
  and testing of RESCUE exchange and modelling
  issues.
• To actively participate in the POSC Shared Earth
  Model and Business Objects initiatives.

15
WORK PLANPhase 2. 1999 2000

• Q1 - Modelling meeting to review proposed
  model changes and extensions.
• Q2 - Implement the results of the modelling
  meeting in the libraries.
• Q3 - Hold an ILAB to test and review the
  extended models.
• Q4 - Hold a commercialization ILAB, and set
  new model objectives.

16
MODELLING GOALS1999

• Handle triangulated surfaces.
• Record history about how a surface/feature was
  created
• Add support for grouping/management of properties.

17
MODELLING GOALS2000

• Support property updates for parts of an existing
  model.
• Modelling of geobodies.
• Capturing optional attribute information, such as
  feature color maps etc.
• Consider a rationalization of the model via a
  more coherent and self-consistent geometry
  description.

18
LICENSING andMAINTENANCE

• The RESCUE model definition will remain in the
  public domain.
• Use of the RESCUE API Class Libraries by
  non-members will be subject to a license and
  payment of a fee.
• All users of the API will pay an annual fee to
  support and maintain the libraries.
• POSC will administer the licensing process.
