1. 1 Global Unique Well Identifier (GUWI) Initiative Progress Report 27 September 2004 (updated for 14 January 2005) Authoring Team: John AdamsConocoPhillips Alan DonigerPOSC Kris GibbonsShell

2. 2 Outline Background to the activity Steering Team members Summary of discussions with data vendors Team discussion results Next steps

3. 3 Background Panel discussion on well identifiers at PNEC Data Management Conference (May 2003) –Ad hoc group of volunteers agreed to work the issue Authoring team established to document the problem and propose a solution (July 2003) Discussion document issued for comment (February 2004) Review of feedback with full steering team (March 2004) Presentations at POSC regional meetings (June 2004) –Stavanger, Houston Discussions with data vendors (potential service operators) (July, August)

4. 4 Benefits Direct cost savings –Replace in-house or contracted management of well/wellbore identity registration, query, and conflict resolution with a much less costly interface/coordination function using the global Well Identity Service. Indirect cost savings –Reduce instances of re-doing work after well/wellbore identity problem is discovered –Simplify data integration –Improve efficiency of A&D activities –Etc.

6. 6 AAPG WWN Initiative Request for Proposal issued by AAPG in January 1995 Key features: –Universal access –Nominal price –AAPG to maintain copyright and oversee administration of the well numbers –No group would be denied access to unique well numbers and basic identifying well data –AAPG reserves right to change vendors Recommendation to adopt Petroconsultants (IHSE) unique well identifier (AAPG Explorer 1996) –The service was initiated and is operational today –Some IHSE clients are registering wells Limited adoption after eight years of operation

7. 7 Service Provider Discussions Provide information on scope and objectives of the Global Unique Well identifier initiative Understand the activities of each service provider with regard to international well data Identify any issues that they have with the proposal Establish their interest in being considered as a potential operator of a well identifier service

8. 8 IHSE IHSE have the most complete international well database. The data is distributed through their applications (IRIS21, EDIN, GEPS...) IHSE have been issuing international UWI’s for clients when requested These UWI’s are then made available to their other clients (within their subscription areas) Clients may not pass the data to third parties as this would breach their contract There has been limited access by non clients IHSE would be prepared to promote the existing UWI more actively and include the process for other E&P entities (seismic, fields)

9. 9 Fugro Robertson Fugro Robertson have built a significant international well database to support multi-client studies (Tellus) and scouting services They fully support the aims of the GUWI team as a means of improving data exchange Fugro Robertson would consider operating the GUWI service and have the infrastructure to deliver a web based solution They are willing to contribute their data set as a basis for such a service Universal access to the GUWI and base well data is not an issue

10. 10 Deloitte & Touche Well established international E&P database distributed through the Petroview application together with online web service Would respond to an RFP for running the UWI service if invited Would contribute their data set to complete the UWI list if all other vendors agreed to do the same

11. 11 Wood Mackenzie Upstream energy market and asset analysis with the following products: EnergyVision, Pathfinder, Electronic Book Interested in maintaining an awareness of the activity

12. 12 Discussion Results: Data Access The Authoring Team asserted that universal access to the basic well attributes is critical to the success of the well identifier initiative –Available to all industry participants (operators, service companies, consultants, academic researchers) on a non- proprietary basis Did the full Steering Team agree that any proposed GUWI solution should have universal access as a fundamental requirement? –Operator representatives plus others: Yes! –Other feedback: 3 rd party operation and industry group oversight are important.

13. 13 Discussion Results: Data Release The Authoring Team asserted that contribution of basic well data by operating companies is a critical success factor Did the full Steering Team believe that their companies would agree to release basic international well attribute data (where local regulations allow) in support of the global UWI initiative? –Including: well name, operator, country, surface location –Operator representatives: Contribution of operator-owned data would be acceptable.

14. 14 Agreed next steps (based on positive outcome of the preceding discussion items) Contact major operating companies to obtain a formal Letter of Intent to release basic well data Prepare and issue a Request for Proposal (RFP) for contractual provision of a Global UWI service

15. 15 Agreed next steps: Letter of Intent Exchange of international well information is made difficult by the lack of common well identification usage. The GUWI Team believes that successful adoption requires universal access to a few items of basic well data (that allow unambiguous identification). Requesting a formal statement of support from operators –Participate in establishment, population, and use –Work with other participants to define and agree on details –Prepared to provide basic well data for operated wells Outside North America

16. 16 Agreed next steps: Progressing by Country Steering Team is collecting a list of countries prioritized by degree of exploration and development activity –To evolve into a plan for populating and deploying –Conditioned by availability of data –Top dozen countries on initial list account for about 150k wells

17. 17 Agreed next steps: Request for Proposals RFP Outline –Introduction: About, How to Submit, Reader Info –Context: Background, Summary, Principles Clearing House Services Customer Request Services Basic Attributes –Evaluation Process: Roles, Steps, Goals –Submitter Instructions: Terms, Format, etc. –Requirements: General, Clearing House, Customer Request –Time Table

18. 18 Conceptual Work Flow Clearing House Service Provider Customer Request Service Provider C Customer Request Service Provider D Customer Request Service Provider A Customer Request Service Provider B Registration Request Query Request Registration Request Query Request Registration Request Steering Group Host: POSC Sponsors

19. 19 Agreed next steps Authoring Team –Complete drafting and editing Steering Team –Review and approve Letter of Intent (Operators and Data Owners) –Distribute and promote  receive Request for Proposals –Distribute and promote  evaluate Establishment of the Service –Evolve to Steering Group  negotiate  contract  start-up
