  1. WITSML end to end implementation: Results and way forwards at Total Raphael Henri-Bally, Total Geosciences IT systems WITSML Meeting Houston, May 15, 2008

  2. Current usage in Total 2 - WITSML Meeting Houston May 15, 2008

  3. Added value of WITSML today and tomorrow • Addresses niche domains: • Lithology • Mud logging • Attributes call for: • Data quality, sanity and traceability • Search tools leveraging • ASCII XML open format ensure: • Unlimited compatibility through mapping • Custom made data sharing & Data Management solutions without duplication of data • Foot print will expend with technological advances • Well seismic (passive, micro) • EOR • Well data shared with other application domains • Drilling • Production • Partners • Economics and legal • Evolution to future technology at minimum costs - WITSML May15, 2008

  4. Background of Total uptake of WITSML • Joined WITSML SIG in 2005: • Well site geology • Geosteering • Well placement • Data acquisition in WITSML in affiliates: • United Kingdom • Netherlands • Indonesia • … • Concurrent with enhanced awareness on Data Management issues • Drawbacks of proprietary formats • New data sets more complex and large • Stronger needs of cross discipline data exchange • Sanity check of corporate exploration data stores worldwide • Preparing for Web Services distribution of reference data - WITSML May15, 2008

  5. A two dimensional expansion • Geographical: • More and more affiliate now familiar with secure data streaming from rig to base are ready for integration and require corporate solution • From acquisition to interpretation: • Leveraging Mud log and Litho logy data for Rig Base and Rig Headquarter collaboration via automated data streaming into G&G application - WITSML May15, 2008

  6. End to end implementation 6 - WITSML May15, 2008 - Références, date, lieu

  7. From Rig to Base and Headquarters Base: Surveillance, QC, Geol Ops + Asset + Drilling + … .. Headquarters: Geol Ops + Asset + Drilling • Mudlogging • LWD • Wireline • Other… Partners Service companies • Composite Real-time displays • Smart Tools for events analysis • WITSML feed to Total applications - WITSML May15, 2008

  8. Requirements : • Cost efficiency: no fancy RTOC • Fast implementation along with drilling • Double replication at base and headquarters • Comply with corporate security policies • Use of a ‘DMZ’ and Firewall to isolate Total and Contractor Networks • Seamless transfer from acquisition to technical interpretation and database • Ex: Pore pressure analysis, petrophysical interpretation • Data streaming into Gravitas • 3 data acquisition companies, 4 software companies: • M/LWD data generated in WITS 0 and converted to WITSML 1.2 • Mudlog and lithology generated in WITSML 1.3.1 - WITSML May15, 2008

  9. Results at base and headquarters During the 2 months length of drilling: • Petrolink tools completed • Onsite aggregation, (WITS0 to WITSML conversion) • Affiliate WITSML servers ( 1.2 and 1.3) • HQ mirror WITSML servers (1.2 and 1.3) • through ‘DMZ’ and Firewall isolating Networks • HRH Gravitas & WinDOT could • read and send WITSML 1.3.1 data • Minor bugs reported • Proposed increased user functionalities • KSI Drillworks Predict – ConnectML • Could read 1.3.1 Major benefits in Well site geology data management and well surveillance - WITSML May15, 2008

  10. Lessons learned • Single version of WITSML to be favored • Back up configuration necessary in case of failure during drilling • 24/7 operations require IT staff availability and bring the industrial culture into the office • Remote access requires explicit naming conventions • Software testing uncover new development possibilities • Technical benefits are Immediate • Faster loop to interpretation • Richer specialist support • Organisational benefits require well site personnel adoption • “Big Brother” syndrome – Possible impact on Well-site Personnel • Distance requires full responsibility of each team member and rigorous data management - WITSML May15, 2008

  11. The way forwards 11 - WITSML May15, 2008 - Références, date, lieu

  12. Ubiquitous web actors • Each of us is now connected everywhere • Each of us is an actor in the chain of processing • Tasks are performed in and out of the organization • We expect from the technical tools the same performance level as private applications • Security rules must adjust to such behaviors • Collaboration tools and Data storage allow us to focus on the content rather than the container • Huge prospect of applications development which understand the documents and actions they are processing for us. - WITSML May15, 2008

  13. Thanks to : • Petrolink (Power suite) staff 24/7 dedication and problem solving qualities • HRH (Gravitas) • Geoservices • Knowledge services (Drillworks Predict and ConnectML) • Total E&P Indonesia - WITSML May15, 2008
