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
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
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
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
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
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
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
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.
Thank You Questions?
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
