E&P Integrated Data Exchange Standards: WITSML™ + PRODML ™ + More
Alan Doniger and Gary Masters, POSC PPDM/PODS Conference Houston, Texas April 2006
Abstract • POSC has a growing portfolio of E&P Technical Data Transfer Industry Standards • The expansion and evolution of these standards began around those for Drilling – WITSML™ – Developments for drilling and – Associated developments of an integrated E&P family of data exchange standards, including Production, Geology and Regulatory and general-purpose E&P data
• Significant progress is currently being in the Production discipline – including transfer standards for reporting, temperature surveys, and optimization.

WITSML Messaging The WITSML standard consists of two sets of specifications – each of which can be versioned independently:
• Data Schema Specifications – XML schemas for WITSML data objects • API (Application Programming Interface) Specifications – defining an optional set of interfaces exchanging WITSML data objects. In particular, the API defined the client-server behavior (Store) and Publish/Subscribe (Publish) interfaces.

The WITSML Vision • Automation of many manual processes in current Drilling Data workflows – Contractors (Service and Drilling) automatically push data into corporate data stores – Partners can automatically pull data for morning reports into their data stores – Operators can push statutory reporting data for reports to regulators – Contractors can share data with one another at the rig site
• A single standard to make the vision possible, reducing industry costs

WITSML’s Fifth Year (2005) • Operators have – Expanded WITSML-based operations – Developed WITSML-required service contract wording – Conducted trial uses of WITSML contextual data – Simplified work flows between acquisition and office – Moved WITSML well plan data between applications – Supported acceptance of WITSML operations report data
WITSML’s Sixth Year (2006) • Operators are – Promoting wider use of WITSML throughout their companies – Upgrading infrastructures to support expanded WITSML use – Developing new WITSML internal champions – Putting WITSML-required contract wording into practice – Refreshing and extending WITSML-assisted business proposals that generate value for short and long-term opportunities
Why Chevron joined the WITSML SIG We
consider WITSML to be the most compelling activity currently in POSC but follow through on all sides is important
Impressed

What Do Service & Software Companies Say About WITSML Standards? • Real-time data in WITSML is key to successful integrated drilling operations (Sense Intellifield) • We enable WITSML data-driven work flows, WITSML-enabled applications, a WITSML-based infrastructure, and a long-term commitment to WITSML (Paradigm) • WITSML enables synchronous remote modeling and surveillance via the Internet (Knowledge Systems) • WITSML enables data interchange with 3rd party applications for wellbore stability, directional well planning, geological modeling, and petrophysics (Baker Hughes)
Future Activities • Next semi-annual events: Houston – May 9-10, SIG Working Meetings • Steering Committee, Specifications Technical Teams, Use Case & Requirements Team, Implementation Support Team
– May 11, Public Seminar and Vendor Exhibition – Host: Schlumberger, Reception Host: Baker Hughes
• Current Release: Version 1.3.1 (Data and API) • Next Version: TBD at May Meetings
Production
ProductionML to WITSML Production • POSC developed a Production Reporting XML schema in 2000: ProductionML • POSC and the Norwegian industry cooperated in a Partner Production Daily Reporting project in 2005 – POSC produced WITSML Production Reporting • Flow Network • Volume Report • Activity Report
– Deployment across Norway in 2006-2007
Production data project - Overview
Goals – One Industry solution in Norway – with all major stakeholders – One common set of definitions for an extensive set of terms used in the production area (data elements) – Standard solution – available for all, built on well known and proven international standards and structures Steps – Define common production terms (Implemented as ISO 15926) – Develop XML exchange format (Based on POSC WITSML) – Implement a data exchange solution for the North Sea Oil&Gas fields (Based on existing hub, LicenseWeb) Benefits – Easy information sharing between companies/applications/work processes – Strong and flexible XML structure enabling dynamic reporting possibilities (Aggregations of data over time and cross fields/wells ) – Allows for timely decision making – An important step to achieving full eOperations advantages
Standards & POSC - Outcome of cooperation with POSC
Agreed on a common approach to XML format Established a common understanding for business and reporting needs Agreed to a common approach for solving issues related to relationship between production data and different field facilities (e.g. well, platform, pipeline) Agreed upon a more reusable XML structure more suited for a global production data approach Agreed on XML structure that will support both reporting needs and possible data exchange needs Agreed XML structure supports different reporting requirements Final outcome: A format suited for more than production data reporting
