Outline

• Background to the activity• Steering Team members• Summary of discussions with data

vendors• Team discussion results• Next steps

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)

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.

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

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

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

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

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

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

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: 3rd party operation and industry group oversight are important.

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

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

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

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

Agreed next steps: Request for Proposals

• RFP Outline

– Context: Background, Summary, Principles

• Clearing House Services

• Customer Request Services

• Basic Attributes

– Evaluation Process: Roles, Steps, Goals
