1. PRODML Review Energistics Western Europe London, 31 May 2011

2. 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

3. “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

4. 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

5. 2011 Development Release 2.1 - 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

6. PRODML Data Objects 1.Flow Network 2.Product Volume 3.Production Operation 4.Well Test 5.DTS 6.Time series 7.Fluid Sample and Analysis 8.Wireline formation tester (coming in 2.1)

9. Slide #9 WFT Probe Types (examples) 9 Single Probe (Weatherford photo) See:~http://www.slb.com/content/services/e valuation/reservoir/quicksilver_probe.asp? Central plus annular Probe See:~http://www.halliburton.com /public/common/Data_Sheets/H 06089.pdf Oval Pad Probe

10. 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

11. 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

12. 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

13. 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

14. 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

15. 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

16. 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

17. 2011 Technology Trends Shared issues across standards Need for cross-standards workgroup to integrate all this

18. 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)

19. 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
