Integrated Operation and economy
•NPD and OLF has calculated the value of IO on the
Norwegian shelf to be 40 billion USD
•Statoil’s 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
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.)
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
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
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

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

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

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
