1. Update on POSC xField WITSML SIG Public Meeting 29 April 2004 Calgary David Archer archer@posc.org

2. POSC xField xField = { SmartField, i-field, e-field, Digital Oilfield of the Future, Intelligent Field, Field of the Future, Digital Oil and Gas Field, … }

3. The Smart Field measure-model-control … measure-model-decide-execute … throughout the asset lifecycle

4. Smart Systems From self-guiding missiles to self-replenishing fridges, the basic approach of all “smart technology” is measure-model-control –measure system properties –model actual vs desired behaviour –derive required correction parameters (adaptive control) –implement control ∆ xField Acquire Model Analyze Control Source: Shell

7. Some related activities CERA DOFF SPE Real Time Operations TIG SPE Digital Energy Study Group API/GCIMT eFields Project Real Time Reservoir Management [TTG Group-OG21] WITSML SIG Strategic Decision Sciences ‘ Roadmap’ UH CIOO … Many internal / joint projects in oil / service companies …

8. CERA DOFF: Potential Industry benefits / remarks Enhanced recovery: 125 billion BOE Lower operating costs: $4-8 billion/year Increased production rates: increase utilization 2-6% Lower facilities cost: 5-10% (3-5 years) Decreased drilling costs: 5-15% But Benefits are not independent, and they require Integration of higher quality data Significant change in organizations and work processes Source: CERA DOFF executive summary Total asset awareness Acting on awareness Increased use of full asset awareness

9. Comments from Operators (re: DOFF) Better decisions faster Prediction vs. reaction $250 million USD / year cost savings It’s not about the technology Integrate facilities, wells, subsurface Find right level of ‘smartness’ for each asset

12. Asset Maturity Model (AAM) Basic - Minimum IT structure, ad hoc processes Standardized - COTS solutions with minimum of customization Structured - Configured / customized IT solutions to meet specific needs for the asset Integrated - Assets networked to operation center(s), EPR systems, wide range of applications and vendors Optimal - Smart devices (with human oversight), field performance integrated with back office, feed-forward and feedback loops for optimal control Source: S.

13. POSC xField: suggested work XML standards for collaboration extending footprint of WITSML to include all data types required for Production System Surveillance and Reservoir Surveillance Smart Sensors what is needed for plug-and-play at each level of OSI model API’s for downhole intelligent devices, protocols (SOAP?), metadata and metadata management Market Studies smart surveillance for “shared services” in data acquisition and management, value-added services (pre-processing, analysis, interpretation) publishing,… potential business models, and implementation technologies: web services.

14. POSC xField Approaches Understanding / problem identification - pursue problems will clear (shared) business purposes Adopt / adapt WITSML -new Data Types to focus on Production Operations - production volumes, production tests, temperature, pressures Focus = Architectures + Data Develop standards via Pilot Projects Players = oil + service + regulators Incremental, rapid results Catalogues of related work / relevant standards

17. An oil company perspective on Standards Standards save money! uniform hardware, applications, data save $100 Million/year Standards lead to better science and increased value Use standards to address interface issues It’s better to get common than to be best Industry standards provide cost effective bridge to the digital oil field

19. The Right Players - clear focus BP & Statoil Baker, Halliburton, Schlumberger, NPSi Commitment Initial funding by oil companies Oil & service companies remain engaged after initial delivery Processes Practical, incremental approach Clear focus on target outcomes - through implementation Frequent communications - steering & technical teams Technologies XML, SOAP Output XML Schema + Server API + sample implementation Openness / evolution Transfer to POSC for commercially neutral custody, publication, promotion and evolution Some lessons learned / best practices
