Real-time data - Success factors

• Easy data access and integration of sub-surface
  data for real-time decision making
• Establish a standardized and automated data
  exchange link between real-time rig site data
  acquisition systems and onshore systems
• All MWD/FEWD service providers connected to the
  data exchange link

Summary

• The need for a standardized and automated data
  exchange link between real-time rig site data
  acquisition systems and onshore systems is now
  being solved through WITSML
• The current focus is on using the real-time data
  in operations. A key factor in this is QA/QC of
  all data that are received through WITSML.

WITSML What now?

• WITSML focus - 1 year perspective
• Current providers and consumers supporting
  version 1.2
• Better stability and data rates
• Other objects in the current standard being
  implemented
• More initiatives and products based on the
  standard
• Statoil focus 1 year perspective
• Using commercial WITSML based software to load
  project databases and feed Operational Centres
  with real-time data during drilling operations
• Using WITSML based software to perform QA/QC of
  key real-time data. E.g directional survey data
• WITSML future focus
• Exploring new areas where the WITSML technology
  can be utilized
