  1. WITSML in Real Life Applications and Case Studies Zach Barfuss Knowledge Systems May 15, 2008

  2. Agenda • Introduction to Knowledge Systems • Value and technology • WITSML case studies • Real-time center environment • Summary and conclusions

  3. Who is Knowledge Systems? • Knowledge Systems is the world’s leading provider of geopressure and geomechanical analysis software and services • Our technology is the most widely used software for pore pressure estimation, geomechanics and real-time surveillance • Our consulting team provide office and well site services globally • 100+ people

  4. Knowledge Systems - technology • Advanced geomechanics and geopressure technologies • Relational database used to store, manage and share pressure-related data

  5. Drillworks ConnectML Retrieves WITS or WITSML industry standard data for real-time pore pressure and geomechanical analysis. The data browser allows you to: • Retrieves LWD and surface logging data from any vendor system • Transmits real-time data over the Internet for global access • Provides quick, easily accessable data using Drillworks applications

  6. Link pre-drill studies with drilling activity • Updating pre-drill models in real-time • Improves results • Decreases uncertainty • Two ways • Synchronous – continuous monitoring and updating (analyst deployed to rig) • Asynchronous – periodic updates once or twice a day (remote monitoring)

  7. Reasons to use Drillworks ConnectML • Reduce non-productive time • Reduce uncertainty while drilling • Create a high quality wellbore

  8. Drillworks ConnectML Workflow

  9. WITSML - case study #1 • Deepwater well offshore Trinidad • Significant uncertainty in subsurface environment • High potential for unscheduled events related to uncertainty • Need for real-time geomechanics modeling • Operator domain expert is not offshore deployable resource • Unplanned requirement ~ low budget & short fuse

  10. WITSML - case study #1 • WITSML used to communicate LWD data from offshore Trinidad • Received into Knowledge Systems Geostress WBS application in Houston • Geomechanics expert performed analysis, then transmitted data back to the rigsite analyst

  11. WITSML - case study #2 • LWD Vendor replaced on rig • Scenario typically causes multitude of data transfer issues • Requires significant work on both sides to regain connections • WITSML provided seamless hookup to new vendor • Did not affect data transfer or remote modeling operations

  12. WITSML - case study #2 • Schlumberger installed WITSML v1.2 server • <10 minutes to reconfigure system • IP Address, User Name, Password, Configuration for server connection • Configure Drillworks data links to ConnectML • Expert began modeling using real-time data • Expert activated WITSML server to make interpretation available to rig

  13. RTOC Physical Layout

  14. Real-time center environment • Provide collaborative atmosphere • Sharing project data among analysts • Distributing information to the stakeholders • Connections to all corporate data • OpenWorks, Geoframe, Recall, Finder • Facilitates data gathering and browsing • Robust interface to rig All based on web services and WITSML

  15. KSI RTOC Strengths • Diversified experience on part of team members (drilling operations, MWD/LWD, directional, petrophysics, geomechanics, drilling fluids) • Have experience with real-time monitoring/surveillance • Has a reputation for competence in pore pressure, fracture gradient, wellbore stability analysis; has some depth of experience and academic expertise in these areas. • Has good software tools for PP-FG-WBS analysis

  16. Direct connection between engineer and rig Isolated from corporate data Non-collaborative environment Statoil workflow - before

  17. Improved connectivity WITSML connections from the rigs WITSML connections to corporate data Delivers increased collaboration among analysts and stakeholders Statoil workflow - after

  18. Summary and conclusions • KSI is using WITSML technology everyday in conventional ways • Remote data transfer • Improve collaboration between rig and office • We are also using WITSML technology in unconventional ways • Connect to corporate databases through a standard protocol
