  1. Role of the Chair OGP - update by Richard Wylde Geodetic Advisor, ExxonMobil Chair OGP Geomatics Committee User needs on energy and minerals data and services Energistics W Europe Region Meeting 31st May 2011 London, UK

  2. Who are the OGP? International Association of Oil and Gas Producers (OGP) • Formed 1974. • Members produce half world’s oil and one third of its gas. • London office (global affairs) since 1974. • Brussels office (EU) since 1992. • Representing some 30 OGP members active in Europe and 72 worldwide. Global standards used locally worldwide

  3. The OGP Geomatics Committee • Formed in 2005 from the European Petroleum Survey Group (EPSG). • Previously known as the Surveying & Positioning Committee. • Comprises of specialists from OGP member companies working in the areas of surveying, geodesy, cartography and geo-spatial information/coordinate data management. • It is the single global source for positioning advice, guidance and formats provision for the upstream oil and gas industry. Global standards used locally worldwide

  4. The OGP Geomatics Committee Main Deliverables • EPSG Geodetic Registry http://epsg-registry.org/ • GIGS (Geospatial Integrity of Geoscience Software – shortly to be released) • Data Exchange Formats • P1, P2 positioning data (under revision, shortly to be released) • P6 Seismic Bin Grid definition (soon to be revised) • P7 Wellbore Deviation Survey (soon to be revised) • Data Models • SSDM (Seabed Survey Data Model – recently released at ESRI PUG) • Standard Legend (under consideration) • Liaison and technical co-operation with other standards bodies • SEG (SEG Y, SEG D, SPS & Seismic Data Management Technical Committee) • Energistics (WITSML, PRODML, RESQML) • ISO (TC211) Global standards used locally worldwide

  5. GN-14 CRSs in Reserves Unitisation Agreements. GN-16 QC of proposed Well coordinates. GN-17 Coordinate Transformation in Gulf of Mexico. GN-18 Guidelines for the conduct of offshore drilling hazard surveys (recently released). GN-19 Guidelines for GNSS positioning in the Oil & Gas industry (shortly to be released). TheOGP Geomatics Committee Technical Guidance Notes • GN-1 (Geodetic Awareness). • GN-2 (Use of Bin Grids in Workstations). • GN-3 Contract Area Definition. • GN-4 Use of the ITRF. • GN-5 CRS definition. • GN-7 EPSG Geodetic Parameter Dataset. • GN-10 Geodetic Transformations offshore Norway. • GN-13 Datum Transformation evaluation & use. Global standards used locally worldwide

  6. Geomatics Committee Geodesy Subcommittee Geophysics Support Subcommittee Geo Information Management Subcommittee Sub-Surface Support Subcommittee Survey Operations Subcommittee Recent developments In progress....... • Seabed Survey Data Model • Oil and Gas Earth Observation Group (OGEO) • Industry Guideline or Specification for Cartographic Symbology • General Geo-Information Guidance note • Development of Ice Atlas methodologies • Spatially Enable the EPSG Database

  7. Recent developments • 3D Bin Grid Task Force Removing the ambiguity and improving interoperability between applications • A P6 format description, possibly integrated in P1/11 • A Guidance Note • A possible extension to the GIGS test data set • A shape file standard for 3D bin grids • GIGS Geospatial Integrity of Geoscience Software • To provide geoscience software developers and users with recommended industry best practice to: • evaluate the capabilities of their software with respect to - establishing and maintaining geospatial data integrity

  8. What is a GIGS software review? A GIGS software review is a structured approach to evaluating the geospatial integrity aspects of software and consists of: • a qualitative evaluation of the software’s geospatial capability by means of a series of checklists; • a quantitative evaluation of the software’s capabilities by means of test data. Software developers and users (i.e. both software vendors and clients) may execute such a GIGS review and both will benefit from its results.

  9. Useful Glossary of Terms(the GIGS review)

  10. Thank You Questions?

  11. The GIGS Review Process To facilitate ease of understanding, the review process has been split into a number of aspects, for each of which a test procedure has been defined: 1. Documentation and Release Notes 2. Pre-defined Geodetic Parameter Library 3. User Defined Geodetic Parameter Library 4. The User Interface 5. Data Operations 6. Audit Trail 7. Deprecation (related to use of EPSG Dataset – see section 2.5.1) 8. Error Trapping These aspects are reflected in groupings, referred to as Test Series. The individual tests are numbered for the purpose of reporting
