Context

• A new Energistics Special Interest Group is being
  formed to participate in the development and
  support of standards for the transfer of
  reservoir (gg and simulation) models. Formal
  launch Jan. 1, 09
• This arises directly from the RESCUE work
• Actively operating for more than 10 years
• Produced class libraries for model exchange
• Supported by energy companies and
  software/service companies
• It has been agreed to provide for an
  implementation of such capabilities using XML
  (and Web Services) to be a parallel effort to
  those of WITSML and PRODML.

Horizon UML model

Horizons with ContourLines (JFR)
General note All features should (in the
future?) have colors/colours associated with them
so that transferring between applications is
consistent
Horizon with null nodes gt zigzag edge
representation, which may have lost information.
So, pass this information along, even if past a
trim line. In addition, projecting horizons past
the trim line to know the un-eroded restored
horizon is very useful for sub-layering,
geostats, etc.
3DContourLine is really TrimLine

RESQML Headlines

• Scope
• Re-development of RESCUE class library as Web
  Services and XML Data Exchange Standards
• Focus Earth models and reservoir models
• Includes support for Geological and Geophysical
  models in coordination with respective SIGs
• Reservoir Characterization with XML
• Earth models, reservoir models
• Data for wells, faults, horizons, stratigraphy,
  etc.
• CRS/projection, units, points, lines, grids
  (points, lines, pillars, etc.)

RESQML Headlines

• Status and Plans
• Formal launch, January 1, 2009
• Operating procedures same as other SIGs
• Preliminary management and technical meetings
• May, July, September, December
• Legacy RESCUE support to continue for 18 months
• Compatibility with other Energistics Standards
• Coordinate/interface with relevant external
  technologies/standards
• OGP EPSG, OGC GML, GeoSciML, etc.
• Market for greater awareness and participation

12
Principle

• Separate concept of EarthModelDocument (not grid
  based) and ReservoirModelDocument (grid based)
• Any ReservoirModelDocument object
  references/contains a EarthModelDocument object

13
Rescue Document

• ltReservoirModelDocumentgt
• ltDocumentInfo/gt ? general info like author,
  datemodified ( Dublin Core)
• ltEarthModelDocument (uri)/gt
• ltCoordinateSystems/gt
• ltGrids/gt ?particular to reservoir model ( GRID
  3D?)
• ltFaults/gt ? points to RMFault
• ltHorizons/gt ? points to RMHorizon
• ltWells/gt ? points to RMWell
• ltStatistics/gt ?summary of general technical info
  on the document ( bounding box, nb of faults ,
  size of grid etc .. to be determined .. short
  info..)
• lt/ReservoirModelDocumentgt
• ltEarthModelDocumentgt
• ltDocumentInfo/gt
• ltHorizons/gt ? points to EMHorizon
• ltFaults/gt ? points to EMFault
• ltWells/gt
• ltStratigraphicColumn/gt
• ltStratigraphicFramework/gt
• ltStructuralFramework/gt
• ltFaultFramework/gt

14
Wells

• ltRMWellsgt
• ltDocumentInfo/gt
• SchemaVersion
• ltRMWellgt
• ltWITSMLWell/gt ? required
• ltEMWellgt
• ltWellResGrid/gt ? reservoir grid representation of
  well (function of time)
• lt/RMWellgt
• lt/RMWellsgt
• ltEMWellsgt
• ltEMWell/gt
• lt/EMWellsgt
• ltWITSMLWell/gt

15
Inheritance

• Entity
• Version, CreationDate, TimeLastChange, Comments,
  ItemState, UID (WITSML/Energistics common data)
• GeometricalEntity ? Entity
• CoordinateSystem reference
• HistoricalReference (part of)
• Reference to Feature
• Other metadata
• EMFault ? GeometricalEntity

Timeline
Needs Updating Please

• December 8-9 Next RESQML working session
  (Houston)
• Go into XML details
• February 9-13 (Denver)
• Library coding session
• Operating Companies or vendors provide
  scenarios, skeleton XML files, use cases for
  testing
• dummy cases for back of envelope testing
• May 4-7 (Calgary)
• Exchanging models
• August/September (Oxford, France)
• Aligned with RESCUE ILAB

18
Conclusions

• The longstanding need for (loose) integration and
  transfer between earth and reservoir models for
  several EP business purposes is being addressed.
• The appropriate technical resources are being
  re-used. Additional expertise, funding, and
  support will be sought.
• Potential participants should contact
