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

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

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 1.3.1

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 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

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

The way forwards

- 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 Huge prospect of applications development
