Wellsite Information Transfer Standard Markup Language, WITSML, an Introduction

Alan DonigerDoniger@POSC.org

WITSML™ – WWW.WITSML.ORG

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

A New Open Information Transfer Standard for the Oilfield

• WITSML started as a collaborative effort to update the widely used WITS standard for moving drilling data between rig and office based computer systems

• WITSML is designed for the standards of today's “always on” Internet environment while still accommodating those rigs not yet “Wired”

• WITSML is published and available to all to implement• Real world use of WITSML is happening NOW• The scope of practical usage is being extended based on

practical experience and pragmatic needs

Right-time Data

• 1980’s WITS real-time binary formats• 1990’s as Internet and related technologies became available,

new solutions emerged – but separately– Statoil developed Drilling Automation Real Time (DART)

• DART evolved into the multi-company WITSML effort

History

Benefits• Improved “plug and play” for moving data between “systems”• Operators: reduce cost, improve vendor competitiveness• Contractors: reduce need to support different systems for

different operators• (Near) real-time, sequential data, but also contextual data

• Wellsite data transferred to WITSML Server• Real time via subscription• Batch via file transfer etc.• Data upload to Total Recall• WITSML API calls from 3rd Party systems

FUTURE PLANS

Version 1.2 Clarifications (as identified)

Version 1.2.1 Minor Updates (release ~ end 2004)

Version 1.3 (release ~ during 2005)

POSC INTEGRATION

During 2004, existing and new POSC data transfer standards are being adapted as part of a broader based family of

standards based on WITSML’s technical architecture and characteristics

WellPath, WellLog, WellSchematic, WellHeader,

LogGraphics, etc.

What’s Happening and What’s Next?

The Right Initial Players - clear focusBP & Statoil

Baker, Halliburton, Schlumberger, NPSi

Strong CommitmentInitial funding by oil companies

Oil & service companies remain engaged after initial delivery

Effective ProcessesPractical, incremental approach

Clear focus on target outcomes - through implementation

Frequent communications - steering & technical teams

Choice of TechnologiesXML, SOAP

Comprehensive Output and DocumentationXML Schemas + Server API + sample implementation

Openness / Evolution

Public seminars and presentations

Transfer to POSC for commercially neutral custody, publication, promotion and evolution

Some lessons learned / best practices

POSC: ObjectivesTo be the facilitative consortium to lead the petrotechnical

industry toward open information standards

To be the custodian of such industry standards, whether developed within the consortium or externally

To facilitate the higher degree of integration required by the upstream collaborative marketplace

and emerging digital technologies

To develop open petrotechnical standards that support the business efficiency of the exploration and production industry.
