IO from ambition to integrated action
Geographical independence
Integration between licensees
Efficient support

• Operation 24/7
• Certifying of competency
• Integrated management
• Real time 3-D models
• Virtual cooperation arena
• Remote support from vendors

• Experience transfer
• Better use of vendors
• 24/7 support on request
• Standardization of toolbox
• Wireless technology

• Land based support
• Real time data
• Increased interaction
• Production optimization
• Condition based monitoring from shore
• Training
• Cooperation rooms

Results Production optimization on Heidrun

• Improved collaboration onshore and
  onshore/offshore
• Better cross-disciplinary understanding
• Working as one team
• This way of working has lead to a more open,
  tighter and better dialogue onshore/offshore. The
  consequense is increased production under safer
  producing conditions
• Production leader at the Heidrun TLP
• Increased oil production by 6 in 2006 gt 500
  000 Sm3/year

Integrated Operation and economy

• NPD and OLF has calculated the value of IO on the
  Norwegian shelf to be 40 billion USD
• Statoils anticipated IO-potential is more than
  50 of the above
• External review of the Integrated Operations
  efforts on one of our major fields calculates the
  value created to close to 1 billion USD, with a
  further potential of 0,7 \- 0,4 billion USD

Current status on the use of WITSML in Statoil
9
Overal use of WITSML in Statoil

• Statoil have transferred information from 300
  wells with the use of WITSML (and stopped
  counting)
• Incorporate all wells operated by Statoil in the
  Norwegian sector
• Incorporate a growing amount of wells
  internationally (Iran, Venezuela, Angola etc.)

10
Current situation from our IT real time support
centre in Statoil

• Period 1/6-06 to 31/8-06
• WITSML 29 wells
• 85 191 m WITSML stream
• 255 571 ft WITSML stream
• PROBLEMS with the start of 50 of these
  streams due to lack of automation

11
Challenges with real-time WITSML stream

• Still many manual operations to set up and
  maintain the real-time stream
• WITSML not properly supporting automisation
• Applications is not properly supporting real-time
  data
• Some of the products in the data stream are not
  built to support multiple well streams (up to 20
  simultaneous wells)
• Manual work needed to handle dialects of WITSML
  and multiple versions in use

12
Good thing about the real-time WITSML stream

• It does its job of transporting data to the end
  users in the operations centres in Statoil
• The users are getting used to the use of
  real-time data due to every well being
  transferred in real-time (it drives habits)
• It is one of the cornerstones in harvesting the
  overall value of Integrated Operations
