Increased revenues - Cost reductions

• Integrated operations
• Production has been accelerated, in some cases
  with 5-10
• The average oil recovery rate has been increased
  from 44 to 50
• Operation and maintenance costs have been reduced
  by 25-40

The Problem

• 50 of the problems in the world result from
  people using the same words with different
  meanings (Theorem 1)
• The other 50 of the problems results from
  people using different words with the same
  meaning (Theorem 2)

Observations

• Standardising Data Models is not sufficient
• Content that shall be shared must also have a
  standardized representation
• Content must be described neutral with respect
  to usage

6
Scope of the Project

• To integrate the following information in one
  standard
• 4C / 4D seismic
• Drilling and logging
• Well production
• Safety and automation system
• Monitoring and operation of subsea system
• Maintenance system data
• Reservoir reliability data
• To investigate real time decision support systems
  that
• Classify and retrieve information using Web
  Ontology Language (OWL)
• Use rule based notification
• Visualize subsurface and operational data
• Automatically link production control and
  reservoir simulation tools (option)

Tyrihans - A Case for the Project

• Tyrihans will be developed as a highly
  instrumented field
• Significant well instrumentation that generate
  real time data
• Permanent bottom cables that generate data for
  saturation and pressure maps
• Changes are monitored on a daily or weekly basis,
  instead of the current 6 month basis
• The integrated information platform will
  represent this information along with other
  information about production, operation and
  maintenance and equipment to make better
  decisions for production improvement

ISO 15926 - Project Methodology

ISO 15926

Include optimal set of real time data from
reservoirs, wells, and subsea production
facilities that are integrated across disciplines
to provide an open and standardised integrated
information platform (semantic database).

MOU POSC and POSC Caesar

• Memorandum of Understanding (MOU)
• Co-operation started in 1995
• Substantial co-operation the first 5-6 years
• Co-operation reconfirmed in a MOU of 1 November
  2004
• Benefits of Collaboration Complimentary efforts,
  joint development of specifications and
  standards. Both parties can use work that has
  already been done
• Recent Meetings September and November 2004,
  discussed the exchange of production information
  being developed for IIP for the drilling
  information developed in WITSML

17
Scope of Production part of IIP

• The Production Stream Model consists of Flow
  Elements or Sections which are of importance for
  production monitoring and regulation of flow.
• Example sections will typically include locations
  along the flowline which contains instrumentation
  for monitoring and/or equipment for regulation.
  (Like choke valves, pressure and temperature
  transmitters, multiphase flow meters, sand
  sensors, etc)
• Activities in the Production Stream Model are
  identified and related to the appropriate
  sections.
• Standardized daily and monthly production
  reporting terms and definitions for operating
  companies and national authorities.
• The next step will be to integrate the production
  activities and corresponding sections with the
  associated equipment, instrumentation,
  corresponding units of measure, etc. by adding
  appropriate relations and associations.
