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

Real Time Data Challenges - Operation and Support
Overview • Since October 2005 • Grane, OSC, OSE, Troll, Njord, Fram Vest • 20 wells, 62 wellbores • Service companies • Baker • Halliburton • End users • RMS • GeoFrame • DrillWorks/Predict • Bore • Morning Status Check • Daily before 08:00

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
