PRODML Background – New Millenium

• Boom in highly instrumented fields. Energy companies keen to exploit opportunity for better use of near real-time data in optimal operation of assets. (aka “Digital Oilfield” etc.)

• Current landscape fragmented – multiple commercial and in-house tools

• Efficient means of interoperability between these tools is essential for more efficient workflows

PRODML Background

PRODML – Work Group ‘06 and ‘07 ParticipantsAn initiative started in 2005 by five energy companies, then joined by eight vendor companies and an industry-neutral standards organization.

PRODML: Business Drivers

• The Opportunity:– Production application domain highly fragmented– Doing nothing requires point to point integration: costly,

slow, very high maintenance Opportunity to fix this!

• The Objective:– Make integration cheaper, faster, simpler– Enable dynamic creation of “value loops” with new workflows

and applications added “on the fly”

• Supply chain models “standards” and “consolidation”– SCADA – many vendors, public standards– G&G/Reservoir – few vendors, de facto standards– Production – industry standards approach PRODML

Scope of PRODML Applications

• Operational Modeling– Predictive algorithms to predict future measurements from

historical measurements and operational plans• Allocation and Reconciliation

– Derives critical values from measurements, as in back-allocation of volumes to wellbores

• Surveillance and Monitoring– Continuous comparison of actual to predicted

measurements; out of range condition invokes analysis • Simulation and Optimization

– Predictive algorithms to predict future measurements and related set points that achieve pre-defined objectives

• Advisory and Alert– Invoked when post-analytical predicted and actual

performance differ significantly; alerts for remedial control changes

PRODML Data Scope

• Production Systems in Producing Fields consist of– Flow Network topology (Product Flow Model)

• Production and injection wells, equipment, etc.• Static Model of Flow connections: outlet to

inlet– Measurements (Product Volume)

• Production volumes and flow rates• Pressures, temperatures, etc.

– Test results (Well Test)• Captures the results of a well test

PRODML – Material Progress 2007-08

• A common language for production data has been created

• Commercial application has commenced, eg:– Production Reporting (Statoil)– Waterflood management (Chevron)– DTS data management (Weatherford)– First Commercial Applications (Schlumberger)

• R&D Proofs of Concept have been substantial:– Gas Lift Optimisation– Downhole sensors– 5,000 well dataset transfers– Network Model changes moving between applications

Group History Mission

SPE Realtime Optimization TIG

Established after SPE forum in July 2001 (“Reconciling realtime production optimization and reservoir management”). Operates under structure of SPE TIGFour SPE papers

To promote and encourage the development of hardware and software tools including associated standards and work processes for ‘real-time’ optimization of hydrocarbon systems

PRODML Started in 2005 by five oil companies. Subsequently joined by service providers / software developers and transitioned to Energistics for stewardshipThree SPE Papers

Develop an open industry standard for data exchange to support production optimization within a ‘digital oil field’ context

SPE IT Section (Oilfield Integration Subcommittee)

Formed in March 2006. First meeting at SPE ATCE in September 2006

Facilitate implementation of the digital oilfield by integration of information technology, people, processes in the oilfield business by:1.Providing best practices for integration of information technology between subsurface and field operations2.Promoting establishment of a new discipline combining information technology and oilfeld technologies…..3.Develop information security best practices…..4.Provide a forum to combine petro-technical information initiatives
