E&P Integrated Data Exchange Standards: WITSML™ + PRODML ™ + More

Alan Doniger and Gary Masters, POSCPPDM/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.


Presentation Topics• WITSML (Drilling) Update

– Web Services, Service Oriented Architecture– History, Participation– Current and Future Activities

• WITSML (Production) and PRODML Overview– Production Reporting– Optimization – The PRODML Work Group– Temperature Surveys– Fluid Analysis Results

• WITSML (General E&P, Geology, Regulatory, Geophysical, etc.)

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

Based on BP slide, June ‘04

Generic Applications

Data transfers via live web services as well as using USB key drives and E Mail in lower

cost environments.

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 by the vendor interactionImpressed by standards that are workingReal implementations, not just theoryEnables the use of Web servicesImportant standard for exchange of dataOpportunity to expand the standard

WITSML - Large Saving Potential when Stable

Save users from loading data manually

- Old- Survey + logs in to RMS

- Download from Baker RigLink- Get data on correct format- Load survey file- Load log file

- 2-3 hours for 2 people- New

- Map WITSML data to well (select survey + log curves )- Once for each wellbore

- Hit monotoring button- 10 mins


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
