1 Future Consideration for WITSML from Total Products should migrate to the same version of WITSML Need provisions for backup in case of system failure Office support should extend to 24/7 operations Global data identification needed Increased requirements for security Newly enabled in-house software developments possible  Focus on the content rather than the container  Focus on understanding the data and actions being processed

2 What are WITSML Benefits for StatoilHydro? WITSML and WITSML-based processes and products can make it cost effective to implement complex and challenging business cases –Complexity of the physical environment –Diversity of service companies involved WITSML can be a catalyst to the identification of new business opportunities Largest well in the Troll field superimposed over Bergen (to scale)

3 Future Considerations for WITSML from StatoilHydro Real-time communications systems can be a challenge in some parts of the world More software application products must be real-time enabled Determine what is “right data” and what is its “right time” Improving consistency in WITSML usage among processes and products –WITSML SIG is beginning to define use case “profiles” Determine how much human supervision and quality control should remain after automation Determine how to handle increased volume from new technologies: wired pipe, well seismic, etc.

4 What are WITSML Benefits for Shell? Moves Data –Effortlessly –Efficiently –Securely –Preserving Vendor Neutrality Enables real-time data flows Supports well planning and design –Relevant data from any system, internal or external –Compare proposal with historical results –Easy data exchange among well engineering applications –Collaboration among geologists, geophysicists, petrophysicists, reservoir engineers, well engineers, and real time application engineers

5 What are WITSML Benefits for Shell? Combining expertise leads to optimal well delivery –Staff on the rig - Wellsite engineer, Wellsite geologist, Drilling supervisor, Mudlogger, Directional driller etc. – can easily share data and have more time to focus on the job –Technical specialists from the office can be intimately involved in the execution of the well, they are fed information from all parties on the rig, and provide advice or intervene when needed –Reduction of personnel on the rig can be achieved thus decreasing safety exposure and costs

6 What are WITSML Benefits for Shell? Improved partner reporting –Timely, high quality exchange of data without restriction on how that data is used or interpreted –Partner can interpret the data independently –Can include daily operations reports, mudlog reports, casing reports etc.

7 Summary and Recommendations WITSML is ready to deliver value for you today. Embed WITSML as part of your real-time data architecture Use WITSML to get the right data to the right person Real-time validation and optimization to improve drilling performance Improve reporting quality with less effort Demonstrate value from WITSML usage and expand scope of use
