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

GFO • Date: 2006-06-12 • Page: 14 • Oil & Energy

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
