2. WITSML Summary Wellsite Information Transfer Standard Markup Language “The ‘right-time’ seamless flow of well-site data between operators and service companies to speed and enhance decision-making ” An Open Information Transfer Standard for the Oilfield

3. WITSML Summary Initial vision of participants –Data Producers –Data Consumers Operators Service Companies Information

4. WITSML Summary Impacted processes –Data Producers Data Acquisition Data Distribution (internally) Data Distribution (externally) Data Management Analytic Solutions –Data Consumers Access to Data Data Management Engineering & Interpretive processes Operators Service Companies Information

5. WITSML Summary Initial Objectives –Enable decisions using ‘Real Time’ data –Simplify data interaction and data reuse –Reduce complexity –Reduce cost Time savings Technology Improvements More accuracy Operators Service Companies Information

6. What would success look like? Goals stated in Real Time/WITSML usage study 1 : “Access to the information I need to make time- critical decisions, regardless of who I am currently working with (as a Service Company)” “Save me 15 minutes a day, by not having to type in some data that is already in electronic format somewhere else” “Allow me to understand what is happening, at anytime, for any (drilling) operations, anywhere” “The ability to use drilling data from any technology provider within our (internal) processes for decision making” “Neutral way of encapsulating information so that it is available regardless of vendor, provider or version of their various technology” Operators Service Companies Information 1 – Marketing Analysis of Real Time Workflow initiatives. Landmark/Halliburton 2004

7. WITSML Evolution - from needs of the SIG members Inter-company communications –Service Co  Service Co –Operator  Operator –Software Vendor  Software Vendor Automatic flow of data –Send and receive with little/no manual intervention –End-user application always updated with current information Data Retention –Vendor, Service Co neutral –Version agnostic Online, on demand –Available as needed –Cross firewalls –Cross time zones Operators Service Companies Information Preservation Analysis Vendors Aggregation Data mgmt Applications Reporting Agencies

8. WITSML – Examples of Use Operating Company “A” 300+ wells affected by WITSML Impact in all regions of drilling activity 2 month study in 2006: –29 wells in WITSML –250000 ft drilled using WITSML Operating Company “B” 87 wells affected by WITSML –51 in first ¾ of 2006 alone Typically 10-15 actively running (WITSML) at any time Typical operations –5 minute update intervals –Operations Support Source – WITSML (October 2006) Public Forum presentations

9. WITSML – Examples of Use Software Use –40+ technology solutions using WITSML (8 reported vendors) 1 –33 vendors participating 1 –Numerous pilot studies 15 with my involvement 6 different Operating Companies Reporting Agency Use –WITSML oriented reporting Example: 1 – Source: WITSML (October 2006) Public Forum presentations Service Co “A” Analysis Co “B” Merge & Stored Co “C” Automatic distribution Co “D” Corporate Application use

10. WITSML – What is next? Challenges expressed by SIG members More Automatic Higher Quality data transfer –Error management Higher Speed Data management Expand data coverage Incorporation by End-User applications Deploy, Deploy, Deploy…

11. WITSML – Success Measurement Are we delivering the objective? –Enable decisions using ‘Real Time’ data Proven and deployed solutions delivering RT data to decision applications –Simplify data interaction and data reuse 90% of data transferred is related to 4 objects Limited use of “Operational Information” –Reduce complexity Incorporation of data has moved from days to hours and minutes Initiation of data use still issue Errors still exist –Reduce cost Time savings –5 minute intervals on loading are now considered “Normal” or “Maximum” Technology Improvements –Application use of RT data increasing More accuracy –Adoption and Use rate indicates value
