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

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.
• Easytouse. 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

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

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.
