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
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
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.
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.
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.
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.
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
Solution Architecture
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 standardsLimitations• At present handles only LAS 2.0 format
Demo of the Application
Demonstration
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.
