Global Unique Well Identifier Initiative

• 7th Data Management Conference, May 03
• Panel discussion led by Kris Gibbons, Shell
• Volunteers formed a working and review team
• Proposal Discussion Document
• http//www.posc.org
• Public comment period February March 04
• Editors
• Kris Gibbons, Shell
• John Adams, ConocoPhillips
• Alan Doniger, POSC

3
Proposal

• Form and operate a world-wide, Well and Wellbore
  Identity Service for the oil and gas industry.
• We believe that this is possible if
• We keep the best interests of the industry in
  focus
• Motivate the most qualified service providers
• Bring to life a standards-based, meaningful set
  of definitions and procedures

4
Proposal

• Primary driver
• Cost savings through reducing or eliminating
  multiple, similar efforts on a company by company
  basis
• The time for this initiative is now.
• Join the effort with your suggestions and
  participation.

5
Initial Team

• Editors John Adams, Alan Doniger, Kris Gibbons
• Reviewers
• Chris Gaudry, MMS
• Richard Hermann, A2D
• Gregory Kushnir, Tobin
• Mike Mishler, ExxonMobil
• Pat Ryan, Nexen
• Damon Simmons, Marathon
• Pete Stark, IHSE
• Chris Troyer, Burlingon Resources

6
Vision

• Create and effectively manage a single point of
  contact for well/wellbore identity registration,
  query, and conflict resolution all available
  without constraint or fees to the global industry.

7
Mission of the Team

• Describe the vision, benefits, costs, etc. of a
  solution sufficiently well to establish the
  feasibility of achieving the vision and to evolve
  the promotion of this initiative and the custody
  of the associated industry standards to POSC.

8
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 AD activities
• Etc.

9
Funding

• Could be supplied by sponsorships from companies
  that will realize the most benefits.
• Value-added services may be added by service
  providers.
• Expanded services for registration of other type
  of identifiers would raise additional funding,
  e.g. for reservoirs, basins, fields, leases, etc.

10
POSC Data Store Solutions SIG

• This user group is focused on standards and best
  practices for data management and data management
  products and services.
• This SIG can host the development of the
  initiative leading to a hand-off to the steering
  committee and organizations selected to carry out
  the service.
• The SIG can serve as the ongoing user group for
  the service.

11
Basic Principles

• Preserve Existing Identification Systems
• Where mandated or historically established
• Worldwide registration to assign otherwise
  meaningless, global, unique identifiers.
• Well surface location based
• Wellbore path from surface to bottom-hole
  location
• Sidetracks, bypasses, re-entries
• Associate with mandated/historical identifiers
• Associate with small set of attributes that aid
  in identification

12
Basic Principles

• Quality Data Control
• Data from registered operator
• Additions and modification follow QC procedure
• Coverage
• Target is at least 90 in each producing region
• Service Level
• Adequate for timely results to queries and
  add/modify requests

13
Basic Principles

• Authorization
• Based on current operator
• Authorized hand-off when operator changes
• Surrogate data owner per region for unrecorded
  (old, not previously known)
• Correlations
• Maintain mappings with mandated/historical
  identifier systems
• Anomalies will be resolved with help of operators

14
Basic Principles

• Getting Started
• Efficient collection and loading process using
  existing sources with verification
• Incremental start-up, e.g. by region
• Sponsored Funding, Governance, Availability
• Universal availability for registration and query
  at no cost
• Funded by sponsoring organizations, possibly
  associated with POSC membership fees.
• Formally governed on behalf of the sponsors to
  collect, disburse, contract, monitor, and ensure
  compliance on behalf of sponsors, hosted by POSC.
• Initial development costs will be separately
  funded.
• Service providers selected by an open RFP process.

15
Basic Principles

• Access Technique
• Interactive Web
• Web Services
• Privacy
• Formal procedures
• Tight wells supported
• Audit Trail
• Accesses and updates

16
Service Functionality

• Customers
• Register wells/wellbores as operator
• Post modifications as operator
• Run queries exact match and contextual criteria
  textual and/or spatial
• Retrieve attributes for selected wells/wellbores
• Retrieve identifiers for entered attributes
• Request identifier translation
• Single point of finding comprehensive, reliable
  well/wellbore identity data
• Issue challenges to content addressed
  expeditiously and reasonably in cooperation with
  operators/data owners.

17
Next Steps

• The current team is preparing a Request for
  Proposal with
• More complete business case.
• More complete service specification
• Industry acceptance plan
• Target Issue RFP this summer with closing date
  in the early/middle fall.

18
Initial Ideas about Attributes

• Notes
• Used for registration, query, and access.
• History maintained for some ()
• Attributes mandatory for registration are
  expected to maintained as current by operators
• Operators are encouraged but not required to
  maintain current values for other attributes.

19
Initial Ideas about Attributes

• Well / Wellbore Identification / Classification
• Mandatory
• Well or wellbore name and number
• Wellbore parent id (root wellbore well)
• Well operator name (data owner)
• Selected well or wellbore local naming system and
  identifiers (e.g., US API, UK DTI, Alberta EUB)
• Well country
• Well surface and wellbore bottom hole latitude /
  longitude locations with respect to a
  standards-based (EPSG) coordinate reference
  system (if known)

20
Initial Ideas about Attributes

• Well / Wellbore Identification / Classification
• Recommended
• Well status
• Well content
• Well spud date, wellbore kick-off date
• Well onshore or offshore indicator
• Well offshore block/block number
• Well field name

21
Initial Ideas about Attributes

• Registration Information
• Mandatory
• Company name
• Company contact name and associated information
• Access restrictions, e.g. for tight wells

22
Comments Received

• Data Vendor
• Need commercial organization to provide the
  service
• Regulatory Agency
• Supports proposal noting key points preservation
  of existing systems, issuing global meaningless
  ids, etc.
• Oil Company
• Use multiple authorized service providers
  (competitive)
• Oil Company
• Interest? Yes. Limit operator obligation to
  service challenges

23
Comments Received

• Data Vendor
• Prior AAPG effort failed to achieve wide
  acceptance due to cost and insufficient
  awareness.
• Oil Company
• Support the proposal. No concerns from a legal
  review. Service must be essentially free for
  basic access. POSC should maintain the standards
  used and monitor service delivery for compliance.
  
• Oil Company
• Support the proposal. Internet access for
  universality.

24
Comments Received

• Data Vendor
• Retain ids where reasonably constructed and using
  new ids elsewhere welcome. Service costs must be
  provided for on a long-term basis. Web services.
  Operators should submit international data. Allow
  value-added integration with other data. Warns of
  costs to manage tight well registration.
• Software Developer
• Note wells found to have no records or approvals
• Oil Company
• Great proposal.

25
Comments Received

• Oil Company
• Provide cross-reference to country-issued ids if
  these are not suitable as primary ids.
• Regulatory Agency
• Supports the proposal. High-level support needed
  from oil companies.
• Oil Company
• Great interest in the proposal. Each subsidiary
  has its own ids now with aliases in the corporate
  data base. Concern of conversion costs.

26
Comments Received

• March 16 from Robert Winsloe, Managing Director,
  International, and Executive VP of IHSE
• Summary
• Petroconsultants developed an non-N. America UWI
  system used in 170 countries by governments, oil
  companies (major, national, independent), and
  service companies.

27
IHSE Comments

• History
• 1995, AAPG RFP to administer worldwide well
  numbers
• For expediting electronic interchange of data
• Petroconsultants response based on IRIS21 UWI
  number
• 20 years experience with 190,000 wells from 170
  countries
• Familiar with diverse reporting requirements
• 1996, AAPG selected Petroconsultants for outside
  N. America
• 1995 to Today
• Annual user meetings most international oil
  companies as users
• Today, reasoning remains valid
• 463,000 wells

28
IHSE Comments

• IRIS21 UWI
• 12 digit number, machine generated, unique, no
  embedded meaning (except Petroconsultants source
  indicator)
• What represents a well? No global definition,
  practices differ.
• UWIs are assigned to Well Bores (as reported)
• Links (predecessor, successor) tie Well Bores in
  a Well
• Cross-references with National systems, vendor
  systems, and organization systems.
• Awareness
• AAPG Explorer article, July 1996 ?
• Petroconsultants/IHSE and clients

29
IHSE Comments

• Cost of Service
• AAPG agreed on a scale of charges, but IHSE has
  not applied it until now What was it?
• Virtually all requests for UWIs come from
  existing IHSE customers
• Only one service company request (small,
  customer)
• Timeliness
• 30-40 UWI requests per week. New UWI in 1 day.
  Potential duplicates are checked.
• Other 12-digit Ids
• fields, reservoirs, geophysical surveys, basins,
  and lithstratigraphic units

30
IHSE Comments

• Conclusion
• Existing system works satisfactorily for users
  and at no additional cost to them.
• IHSE spent money to acquire data for requested
  wells, to process data, to quality check data to
  prevent duplicates, and to load data.
• We hear the concern expressed that UWIs are not
  openly available (e.g., to service companies).
• We have the concern of not providing competitors
  data resources substantially below our cost.
• It is the association data more than the UWIs
  that are a concern.

31
IHSE Comments

• Conclusion (continued)
• Majority of desired features are covered
• UWIs for well bores, well bore links,
  cross-references
• More cost-effective to promote and extend this
  working system than to start over
• If an RFP is issued, IHSE wants to receive it.
