1. 1 Agenda Introduction Energistics Standards Panorama / History / Participants Web Services Interoperability Standards v1.0 WITSML Version 1.x Services / Data Specifications PRODML Version 1.x Services / Data Specifications RESQML plan Adjacent Technologies and External Specifications Subjects for Subsequent Meetings Candidates for Next Stage Deliverables Next Steps Adjourn

2. 2 A new Energistics Special Interest Group has been formed to participate in the development and support of standards for the transfer of reservoir (g&g and simulation) models. Formal launch: Jan. 1, ‘09 This arises directly from the RESCUE work –Actively operating for more than 10 years –Produced C++ 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. Context

3. 3 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.)

5. 5 Status and Plans –Formal launch, January 1, 2009 –Operating procedures same as other SIGs Steering Committee Use Case and Technical Teams Legacy RESCUE Team – continues until RESQML matures –In-person meetings May 4-7 in Calgary (RESQML) August in Cambridge England (RESCUE and RESQML) –Compatibility with other Energistics Standards –Coordinate/interface with relevant external technologies/standards OGP EPSG, OGC GML, GeoSciML, etc. –Market for greater awareness and participation RESQML Headlines
