Integrated Operation and economy

1
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

2
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.)

3
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

4
Challenges with real-time WITSML stream

• Still many manual operations to set up and
  maintain the real-time stream
• WITSML not properly supporting automation
• 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

5
Good things 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

Right Time Data

• Update speed
• lt 5 mins is accepable
• Operational Support
• (not Operational Control)
• Drilling and Well Operations
• WITSML

• WITSML
• Well
• Wellbore
• Trajectory
• Trajectory Station
• Log
• Rig
• Realtime
• bhaRun

12
Current WITSML Status

• Generally 10 15 parallel drilling operations
  are active at any time all using WITSML.
• WITSML has been in operations for nearly 3 years.
  In total, 87 wells drilled with WITSML so far.
• 2004 and 2005 36 wells
• 2006 already 51 wells

13
Service Companies WITSML Data Deliveries

• Stable deliveries most of the time
• Still some erroneous data
• Wrong wellbore
• Data too deep
• Missing data
• Re-load of data
• Conclusion This will always happen ? We need
  better data management tools
• Issues with the WITSML delivered from service
  companies
• SiteCom in Hydro based on active wellbore flag
• Do we read the same data over and over again from
  the service companies?
• Append mode versus overwrite mode
• Conclusion The goal is automated data transfer
  with as few re-reads as possible

14
Challenges, Real Time Data in Hydro

• Continuos stable delivery from service companies
• Need Active wellbore update date
• Better quality check of data before delivered to
  Hydro
• If wrong data, need to do full refresh of all
  data on SiteCom and end user applications
• New WITSML data types
• Amount of data for time logs/curves
• When will service companies be able to deliver
  new data types?
• Update speed from service companies
• Transfer all data only once
• Error recovery speed
• Errors will happen, important to recovery quickly
• WITSML Version 1.3 deployment to replace WITSML
  Version 1.2
• 2007/2008
