  1. WITSML Use Cases Calgary Workshop April 2004

  2. Use Cases / Practical Implementations of WITSML • Where are we now ? • Different drivers in different Operators • In BP, still mainly driven by LWD data applications • About to pilot real time Torque and Drag applications (Available from service contractors for some years) but in an application independently of data acquisition contractors • Geographically in use in Norway, UK, Trinidad and Azerbaijan • Still need to get contextual data flows up and running. Push into new areas ?

  3. “Real Time” • A successful, but limited implementation, focussed around LWD data, that does not change the principle of the way WITS data was used • The challenge is to deepen the useage to include the static contextual data, far easier to handle with WITSML than was the case with WITS. • Where do we want to be ? Instigating technical changes that will make the flow of data more automated, saving cost through removing duplication of data entry.

  4. BP interest in applications of WITSML • Operator to Government • Service Contractor to Service Contractor • Drilling Contractor to Operator • Service Contractor to Operator  • Operator to Operator  • Application to Application

  5. Operator to Government • Operator to Government  • Example: Filing of statutory documents relating to the well permitting process. • PON 9 etc. • Action – Work closely with DTI and other operators (MMS, NPD … ) in piloting a project.

  6. Service Contractor to Service Contractor  • Service Contractor to Service Contractor  • Example: Sharing a BHA description at the rig between different service vendors • Action : Select project to pilot workflow on.

  7. Drilling Contractor to Operator • Example: Automation of transfer of electronic IADC report data. • Action: Engage custodians of IADC electronic report • Select data objects. • This is going to take effort and a strong case to reach implementation • Continue to build a dialog with IADC and their applications community • Select pilot where short term value can be demonstrated

  8. Service Contractor to Operator  • Examples ; • WellpathML, • Geological data (Lith and text descriptions, contextual data, in addition to time based data) from Mud Logging company into Wellsite composite log package. • Wellsite composite log package into corporate data store • Action: Pilot workflow in real environment.

  9. Operator to Operator • Example: Daily drilling report object, ideally with contextual engineering data of value. • Action: • Agree scope and location of pilot

  10. Application to Application • Application to Application  • Example: Migrating data from one application’s proprietary data format to another, using the WITSML API as the mapping tool. • Action: Identify object and project • Completion diagrams ?

  11. Wednesday meeting • Commercial drivers for deeper implementation • Drilling reports • Engagement w IADC & CAODC for Drilling Contractor to Operator • Operator to Operator • Service Contractors reports, DD, LWD, Mud Log, Fluids • Drilling Contractor to Svc Contractor • Regulatory reporting • Well Schematic & Completions • Well Planning / WellPath ML • Production data and DTS • Mud Log data • Extending WITSML to Database to Database transfer ?

  12. Actions from wednesday • Consolidate known industry public domain lithology dictionaries, in addition to Shell Operations Geology handbook, offered by Shell • Supply to group relevant bibliography material where available • Circulate enhanced PIDX nomenclature for completion components, to work toward a standard catalogue Noun, Verb, Modifiers, but keep intelligible eg Pump, Centrifugal, Electrical (ESP). Info from PIDX and ChevTex, others welcome

  13. Process issues • Formalise processes for version release approval • Pilot a process to flow a suggested change into acceptance, using the changes needed to move WellPath ML into an integral part of WITSML • Restate use cases as “Business Problem / Solution” statements • Formalise a list of non technical issues on a bulletin board for members • Slightly more formalise communications between steering committee, Tech teams and Use Cases

  14. Co-operate ! • BP keen to adjust our priorities for work with the WITSML community to foster co-operation • Keen to see projects driven from bottom up, not top down
