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

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

3 - WITSML May15, 2008 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

4 - WITSML May15, 2008 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

5 - WITSML May15, 2008 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

7 - WITSML May15, 2008 Partners Service companies From Rig to Base and Headquarters Mudlogging LWD Wireline Other… Headquarters: Geol Ops + Asset + Drilling 1)Composite Real- time displays 2)Smart Tools for events analysis 3)WITSML feed to Total applications Base: Surveillance, QC, Geol Ops + Asset + Drilling + …..

8 - WITSML May15, 2008 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 Requirements :

9 - WITSML May15, 2008 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 data  Minor bugs reported  Proposed increased user functionalities KSI Drillworks Predict – ConnectML  Could read  Major benefits in Well site geology data management and well surveillance

10 - WITSML May15, 2008 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

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

12 - WITSML May15, 2008 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. which understand the documents and actions they are processing for us.

13 - WITSML May15, 2008 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 This test would not have been possible without your dedication!
