PRODML Review Energistics Western Europe London, 31 May 2011
Summary - Aims of Presentation Review background Short term re-energize New Capability: Wireline/Drill Stem Testing Plan: Completions Find compelling business cases Request member involvement
“A Brief History of PRODML” ‘05 – formed by majors, invited service co’s ‘06 – $1.25m, Focus “DOF”, 4 pilots, plug & play demos, ATCE launch v1.0, SPE paper ‘07 - ~$0.7m, 7 pilots, 2 reporting, 1 DTS, 4 DOF, ATCE roadmap & 2 SPE papers ‘08 – slowing momentum, 1-2 pilots, SAM/GDA ‘09-’10 – fewer initiatives, incremental release
Re-energize during 2011 Demonstrate essential commitment by maintaining annual & “responsive” releases Identify a Compelling Business Case objective, achievable in 1-2 years, with commitment of current SIG membership to contribute Refine roadmap longer term around industry desires & matching commitments
2011 Development Release pending adds Formation Tester Saudi Aramco requests - incr. release Gain Aramco involvement and usage Completion Object – start work Work with WITSML Ensure Business Case & use cases understood & supported Regulatory reporting - prep. for 2012 Interact with NDR SIG to gain requirements

Slide #9 WFT Probe Types (examples) 9 Single Probe (Weatherford photo) See:~ valuation/reservoir/quicksilver_probe.asp? Central plus annular Probe See:~ /public/common/Data_Sheets/H pdf Oval Pad Probe
Slide #10 WFTs: Multiple Layers Tested Can test, sample, analyse and report flowing interval by flowing interval. Each “stop” is referred to as a Station
Slide #11 R1 Results Derived From Results WFT Station Sensor 1 Sensor 2 Tests Samples Events Example: property measured in test 2 is used to derive results from test 3 Methods Results R2
Slide #12 Results across stations upscaling, form eval., res.descr. Results apply at each station individually, but also across multiple stations. WFT Stations Property Profiles Property Gradients Std. Logs
Slide #13 Completion Data Drilling Production Perm. Gauge DTS Flowing Intervals, sensor depths Drilled Well Completed Well Perm. Gauge DTS Surveillance / Reporting E.g. Gas Lift Change Optimization Optimization using models New Completion Drilling & Completions Domain Production Domain Workover Planned Tubing Perforations SSSV Packer Completion DB Well Services Drilling system WITSML Drill Complete
Compelling Business Cases – e.g.’s Completions (D&C life of well) NDR and/or NOJV reporting Service company data (field office) DOF Formation Evaluation How? Member commitment to “make it happen” Roadmap Iterative approach to thorny problems
2011 Promoting Awareness Take story back to key members Promotion/assessment: current capabilities e.g. survey of well test use (?others, e.g. reporting, DTS, etc.) Initiatives: compelling but achievable aims Get right expectations and engagement
2011 Processes Requirements capture - Use Case Team Completions Regulatory reporting Development - Specification Team Data schemas & services Support - Deployment Support Team Documentation and help No team or resources currently in place
2011 Technology Trends Shared issues across standards Need for cross-standards workgroup to integrate all this
The Team Jim Green (CVX) – Board sponsor Bill McKenzie (CVX) & Mike Knewtson (SLB) – Spec Team co-leads + ~6 regular Dave Shipley (CVX) & TBC (svc co) – Use Case Team co-leads + ~ 2-3 regular Jerry Hubbard, Jana Schey, Gary Masters - Energistics Laurence Ormerod – PM (part time role)
Our Need Please get involved!! Any input welcome, esp: Use Case Team (details or long term vision) Deployment Support We want to be led by real world deployments
