  1. LAS To WITSMLConversion Utility Presented at POSC Regional SIG meeting Stavanger, 13 -14 June 2006 by POSC & Satyam Computer Services Ltd

  2. Agenda • Project Objectives • Problem Definition • The Solution and Solution Architecture • Technical Features & Limitations • Demonstration • Current Status & Future • Contacts

  3. Project Objectives • To produce a tool to convert LAS log data to WITSMLTM with interactive and batch interfaces • To stimulate an Open Source development community around the WITSML initiative • Seed funding provided by BP • OS Community to be managed by WITSML and other POSC SIGs

  4. LAS To WITSML - Problem Definition To develop a utility: • For use by operators, contractors, and other organizations; • For use by log analysts, petrophysicists and data managers. • To convert existing log data from CWLS LAS 2.0 and 3 formats into WITSML™ wellLog data representation

  5. Problem Definition Contd.. • Use batch, scripted, and/or interactive user interface • Address depth-based and time-based LAS structures • The solution must be capable of running in a Windows XP operating system. Platform independent solutions are welcome.

  6. Problem Definition Contd.. • Should support identifying and confirming selected input data and saving output data under user-defined names in user-determined locations. • The technology must generate WITSML log and wellLog object instances as well as other WITSML object instances needed to fully map the source data.

  7. Problem Definition Contd.. • The technology must be able to render the output data in a compatible LAS form using an XML style sheet. • The technology must include samples of valid input data to verify correct operation and that data must pass the CWLS LAS validation process.

  8. The Solution – Features Provided • GUI based application– can handle single / multiple files for conversion. • Easy–to–use. Very intuitive design to assist novice users • Handles both Time based and Depth based LAS2.0 files. • Developed and fully functional on Windows 2000 and Windows XP Operating systems. • Uses Java technology that facilitates porting to other operating systems with much less effort.

  9. The Solution – Features Provided Contd.. • Offers flexibility to the user in choosing various optional data that needs to be converted / excluded from conversion. • Generates WITSML Log and WellLog objects and other objects as required based on input data. • Output is in the form of XML files that can be rendered in any desired form using the style sheets. • Provision to the users to modify the mapping scheme between LAS and WITSML elements. • Batch processing facility to process multiple files

  10. Solution Architecture

  11. Technical Features & Limitations The application • Is fully functional on Windows 2000 / Windows XP • Uses JRE 1.4.2_10 • Desktop client application • Flexibility to modify default mapping • Open source standards Limitations • At present handles only LAS 2.0 format

  12. Demo of the Application Demonstration

  13. Current Status and Future • Current Status: • Application has been submitted to POSC for acceptance testing • Future Scope of work: • Enhancements based on feedback from POSC & Industry • We solicit the industry to provide feedback on the same so that the utility can be made more useful for the industry.
