Standards (PWLS)

• Norwegian Petroleum Directorate
• Tuesday June 15 2004
• Eric Toogood, Project Manager Diskos

Diskos The Norwegian National Database for
Seismic, Well, and Production Data

• Well Data is a key data type

• Objectives
• Overall
• To build and maintain a National Digital Library
  for well data from the Norwegian Continental
  Shelf - NCS
• To serve the needs of the NPD and allow access to
  entitled oil companies
• The Reporting Procedures
• Reported data must be structured and named to be
  compatible with the National Database
• The activity of reporting is aligned as closely
  as possible with the oil companies normal
  business needs
• The Reporting Standards
• These are set by the database structure. Now
  HIGHER than previous industry practice

Well Data in Norway - History

• The Diskos group of companies has had an ongoing
  focus on improving access to well data since the
  late 1990s
• There has been collaboration with POSC on this
  issue throughout this period
• Work performed in Diskos Well Data Work Group in
  collaboration with
• Petrodata, Flare Consultants, POSC and now
  Schlumberger (Sinas)
• Focus on the clean up and loading of historical
  (legacy) data
• Establish streamlined procedures for handling
  well data throughout the workflow

4
The Importance of PWLS in Norway

• Quick and efficient loading procedures and
  efficient retrieval and transfer of well log data
  is essential to the Diskos initiative
• In order to make the standard work we must have
  commitment from all the stakeholders
• Authorities (NPD)
• Data base operator (Schlumberger)
• Operating Oil companies
• Licence Partners
• Service Companies
• POSC to develop and manage the standard

5
The Aim Curve level filtering

• Data Overload
• Business Value is concentrated in a relatively
  small number of data curves - filtered views
  focus on high value data

50,000 'Visible' Acquisition Curves
500 Useful Curves

PWLS Aims

• Objectives
• define standards necessary for the creation of an
  organized, clearly labeled and accessible
  well-log database
• Concentrate on the long-term data storage
  problems
• Build on existing work and standards where
  possible
• Concepts should be equally applicable to both
  'Data' and 'Hard Copy'

7
Business Benefits

• Reduced costs or increased efficiency
• significantly lower costs to maintain 'load
  lists'
• less time wasted in identifying data for experts
  and non-experts
• faster data preparation and acceptance for
  exchange/sale
• trades, asset/licence swaps and disposals,
  mergers
• Increased Effectiveness
• clear data organisation and naming will improve
  use and maximise value-add potential
• Creating value for Oil Companies and the
  Norwegian State
• More efficient exploration and development
• More time spent on useful work (rather than
  looking for data)
• Improved decisions

8
Transfer of Data and Operations

• At the end of 2002 the contract for the
  management of the Diskos database was awarded to
  Schlumberger (2004-2008)
• Through 2003 Diskos focused on the transfer of
  data and operations from Petrodata to
  Schlumberger
• Diskos was not able to give attention to the PWLS
  initiative
• Last PWLS meeting was held in October 2002
• PWLS is again a major priority in Norway
• Aims
• - Improved access to data already stored in the
  Diskos database
• - Streamline loading procedures for all new well
  data

9
June 2004 meetings (Stavanger/Houston)

• Renewed focus on the initiative
• POSC must
• Identify the most pressing issues that need to be
  addressed from
• The operator point of view (receipt and loading
  of data)
• The service company point of view
• - The end-user point of view (use of the data)
• Decide on a list of Actions and time scale for
  deliverables
• Coordinate other groups through similar meetings
  in USA (Houston)
• Examine and discuss mechanisms for the
  maintenance and further development of the
  standard
