  1. The Importance of the Geospatial Component of Geophysical Data Management in the E&P WorkflowJonathan P. Stigant, Devon Energy Corporation • IAGC Annual General Meeting • February 19th, 2009

  2. Introduction and Overview • Introduction to Devon • Big Picture • Long Term Industry Goal and Geospatial Trends • Devon E&P Workflow • Geospatial E&P Quality Workflow • Geospatial Seismic Quality Workflow • Some Case Histories and Statistics • Focus on • Industry Connections and Standards • Geophysical Data Management Best Practices • Conclusions and Recommendations www.devonenergy.com

  3. Devon Operations • Largest US Independent • Specialties • Unconventional Shale Plays • GOM/Brazil/China Deepwater • Canada Tar Sands www.devonenergy.com

  4. Industry Focus – ‘Long Term’ • Hydrocarbons, especially Oil • Increased demand – Developing World NOCs • Slow Growth of Alternatives • Increasing E&P Costs • General Promoted Solutions: • New technology • Opening More Areas to Drilling • Encouraging Alternatives • Not Generally Mentioned: • Doing the Basics Better • Collaborating on Industry Standards (NOCs) • Better Data Management for ‘Identity’ and ‘Location’ of assets www.devonenergy.com

  5. Devon’s E&P Value Chain www.devonenergy.com

  6. The Three Most Important Things! Treasure Island Latitude Southeast54 paces Southwest42 paces X Longitude Location, Location, Location www.devonenergy.com

  7. Geospatial Trends • Mapping Principles/No Change • Understanding Geodesy is the foundation of all good surveying and maps • Cartography describes the mpping science • Technique/Revolutionary Changes • GPS is the survey utility of the 21st century • GIS is the mapping utility of the 21st century • Over 75% of our data is spatially referenced, whether we know it or not! Bottom Line - Doing it right the first time can save our Industry millions of dollars www.devonenergy.com

  8. Geospatial Trends • Mapping Principles/No Change • Understanding Geodesy is the foundation of all good surveying and maps • Cartography describes the mapping science • Technique/Revolutionary Changes • GPS is the survey utility of the 21st century • GIS is the mapping utility of the 21st century • Over 75% of our data is spatially referenced, whether we know it or not! The corollary is also true! www.devonenergy.com

  9. Geospatial Management in the E&P Workflow ReservoirManaget &Productn Facilities&Pipelines Property Lease Acquisition&Processing Data Loading&Interpretation Drilling Incoming and Internal Database Audit Software Audits Proprietary/Purchase Seismic Data QC Audit Data Loading Audit Proposed Wells vs. Loaded data Audit Surface and Directional Borehole Positioning Audit Construction Maps and Operations and Reservoir Data Load Audit Block Boundaries in Contracts and Land Grid Data • Data Management • Boundaries • Culture (Coastline, Roads, Rivers etc) • Wells • Raster/Imagery • Application Management • GIS • Interpretation System • Middleware • Well Data Apps • Reservoir Modeling and Engineering • Pre-Lease • Lease Contract • Boundary Definitions • Prospect Evaluation • 2D, 3D Seismic • Acquisition & Purchase • Seismic Processing • Velocity/Gathers • Load Sheets • Data Loading • Interpretation • Proposed Well • Volumetric Analysis • Drilling • Directional Drilling • Site Survey • Pipelines/Facilities • Reservoir Management • 4D Seismic • Production Functional Activities System Activities GIS and Mapping Management Requirement Reformatting, Re-referencing and Re-presenting Spatial Data Auditing www.devonenergy.com

  10. Tipping Point! • Data Types • Seismic • Well • Boundary Components • Substance • Identity • Location Current Industry Data Status (Databases and Projects) • Seismic –35-40% missing or mis-reported data • Surface Well –40% misplacedby > 100 ft • Sub-surface Well –25% misplacedby >200 ft • US Land Boundary –30-50% misplaced www.devonenergy.com

  11. Some Causes • Lack of • Poor Cross Functional Collaboration • Education And Training • Geospatial Detail • Spatial Metadata (Datum Projection, Convergence…) • Spatial Quality Attributes • Geospatial Design In Applications • Supplier Contract Specifications And QC • Defined Supporting Deliverables • Checking Documented Coordinates (Typos) • Desire For Automation At The Expense Of Accuracy www.devonenergy.com

  12. Geospatial (Geodetic) Review Process • Utilizing project data verify that: • The Survey is located correctly • The Geodesy relating to the project is right • The various data sets containing coordinate data are in agreement • Evaluate Proposed Well Location versus Original Geophysical Data • Project Data Utilized: • Navigation Bin Center Coordinates in industry standard formats of UKOOA P1 or SEG P1 • Work Station LoadSheet • SEG Y Trace header Data • Survey Perimeter Outline Point file Link www.devonenergy.com

  13. Focus in on Seismic Data Delivery Current Performance www.devonenergy.com

  14. Wrong SEGY EBCDIC Header Information • Navigation Bin Centers and LoadSheet comparisons on initial data delivery • Navigation P1, SegY seismic data, LoadSheet, Survey outline had different errors and all were replaced www.devonenergy.com

  15. Impact of Poorly Positioned Data www.devonenergy.com

  16. Land Lease Liability Location from Survey Coordinates Tract Northing Mapped Land Grid 3D Survey Easting www.devonenergy.com

  17. Land Lease Liability Location from Survey Coordinates Tract Location from Map Land Grid Measured relative to True Land Grid True Land Grid Northing Mapped Land Grid 3D Survey Easting www.devonenergy.com

  18. Proposed Drilling Location • Two Surveys • Interpreter complained that one was mismatched with the other • One survey loaded with new corners, but datum labeling not changed • Result – 250 meter error • Question – would we have found it if there was only one survey? www.devonenergy.com

  19. Industry Collaboration Examples • Communication with Geophysical Contractors on Deliverables • International Oil and Gas Producers Association (OGP) • Survey and Positioning Committee • EPSG Geospatial parameter Database • Spatial Formats • Regional Petroleum Survey Groups – APSG • APSG – Americas Petroleum Survey Group • Houston Based • Two Meetings per year (February 26, 2009) • ESRI Petroleum Users Group • Annual Meeting in February (Feb 23-25, 2009) • Energistics (POSC) • Data Management SIG • Geophysical SIG • WITSML www.devonenergy.com

  20. Geospatial Integrity of G&G Software JIP Participation 13 Operators 6 major Vendors • Applications • OW/Seisworks • Geoframe • ESRI ArcGIS • Petra (If time and budget allow) • Objectives • Software improvement guidance to vendors • Development of accepted industry standards and specifications • Create a vendor self verification process of geospatial integrity by 2010 20 www.devonenergy.com

  21. Application Geospatial Reviews • Introduction of Geodetic and Cartographic Functionality • Already Done • Geoframe (2005) • Petrosys (2006) • Petra (2008) • None achieved without significant problems • Others as yet unchecked • Finder • Trango • FME • Forthcoming • Petrel 2009 • R5000 www.devonenergy.com

  22. Conclusions and Recommendations • Industry and Company Focus • Promote Standards - Collaboration to have one set of industry standards • Across All E&P Disciplines • Operational and Data Management Support • Independent Quality Assurance (Field and Office) • Geospatial Standards for • Field Operations, Data Processing, Data Licensing, Application Licensing • Detailed Workflows (Link) (Link) • E&P as Data Custodians (vs. IT) • Fit for Purpose/Quality Measures in DBs • Geospatial Component of GG&E Applications • Review before Implementation • Strategic Collaboration • Education in Mapping Sciences - Geodesy & Cartography • Training in College • Companies www.devonenergy.com
