1. 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

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
= m WITSML stream
= 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

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: 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
