© Copyright 2005 POSC The Original 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 (Not images) 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 rigsite A single standard to make the vision possible, reducing industry costs Based on BP slide, June ‘04

Benefits Active and visible WITSML community Shared funding of WITSML custody, support, and promotional activities Active outreach to align WITSML with other initiatives –Within POSC, the expansion of WITSML architecture across all technical E&P data transfer standards: Integrated Operations (Production), Well Log (Wireline), Regulatory, Laboratory, Reference, etc. –Within the industry with other industry groups: UKOOA and US MMS (well path), PPDM (use of POSC exchange and reference standards), Government agencies (regulatory), XML and SOA (OASIS, W3C, OpenGIS, OpenGroup), etc. Vendor neutral promotion of WITSML use and maintenance of WITSML specifications and materials

© Copyright 2005 POSC Why has the WITSML initiative been successful? Some lessons learned / best practices The Right Initial Players - clear focus BP & Statoil with Baker, Halliburton, Schlumberger, and NPSi Strong Commitment Initial funding by oil companies; Oil & service companies remain engaged after initial delivery Effective Processes Practical, incremental approach Clear focus on target outcomes - through implementation Frequent communications - steering & technical teams Choice of Technologies XML, SOAP Comprehensive Output and Documentation XML Schemas + Server API + sample implementation Openness / Evolution Public seminars and presentations Transfer to POSC in early ’03 -- commercially neutral custody, publication, promotion and evolution

© Copyright 2005 POSC What we must do in the future? Maintain enthusiasm for the vision Continue to involve interested and committed, knowledgeable people Address use cases that add real (quantifiable to management) value Keep the spirit of trust and cooperation between competitors Have oil companies supply chain management provide contractual re-enforcement Increase cooperation among different domains to minimize duplication working with similar types of data and to maximize re- use of work already done Continue to work with other organizations, such as PPDM, to maximize alignment of data exchange specifications as well as vocabularies and reference data Based on BP slide, June ‘04

© Copyright 2005 POSC Version 1.3 and Highlights

© Copyright 2005 POSC WITSML Version Highlights General –Data object (schema) and Server (API) specifications are now independent and will evolve separately –First new (non-drilling) data type added (DTS) which re-uses and conforms to WITSML specifications –Many small corrections and enhancements based on implementation feedback

© Copyright 2005 POSC WITSML Version Highlights Improvements –Consistency: realtime and log objects –Tighter constraints on individual values –Mud log upgrades to handle time logs –Log enhanced to handle array data and multiple passes wellLog replaces WellLogML

© Copyright 2005 POSC WITSML Version Highlights Additions –Distributed Temperature Survey –Composite object schema –New measure types with enumerated Unit of Measure values –Well datum capability –New Risk object –Realtime object handles data-groups, multiplexed and de- multiplexed data

© Copyright 2005 POSC Extending WITSML WITSML’s original mandate for wellsite-to- operator (contextual and real-time) data transfers can extend to operator-to-wellsite and operator-to-regulator transfers –And data-flows to partners, to labs, and more –All with a common architecture, common terminology, maximal commercial product and service incentive, etc.
