About Canadian Well Logging Society
The Canadian Well Logging Society (CWLS) is the oldest organization devoted to log analysis, incorporated in Calgary, Canada in 1957. In that time the society has endeavored to produce a technical journal with a Canadian slant. The CWLS is thus an appropriate place for those interested in exploring mineral resources in the Western Canadian Sedimentary Basin, the Canadian Arctic, offshore eastern Canada and southern Ontario.

The society has great support from the petroleum industry with over 30 Corporate sponsors. The CWLS has in turn provided a great deal of support to the petroleum industry. One of our proudest achievements has been a Catalogue of Water Resistivities in sedimentary formations in Canada.

The CWLS holds a Technical Luncheon on the third Wednesday of every month (except in the Summer and February) for the benefit of those interested in log analysis and petrophysics. Notices of the topic of each luncheon are sent to members and posted on this web site.

Currently the CWLS has over 600 members including over 100 Student members from around the world. Most of the activities of the CWLS are performed by Volunteers. The society would like to thank all volunteers for their time and effort in making the CWLS a success.

CWLS is a proud member of Canadian Association of Earth Sciences

Society Objective
The objective of The Society (as stated in the Letter of Incorporation) is the furtherance of the science of well log interpretation, by:


 * Providing regular meetings with discussion of subjects relating thereto; and
 * Encouraging research and study with respect thereto

Membership Qualifications
Active membership is open to those within the oil and gas industries whose work is primarily well log interpretation or those who have a genuine interest in formation evaluation and wish to increase their knowledge of logging methods.

Fees
The CWLS fiscal year commences March 1, and all fees are due at this time. Fees are as follows:


 * Initiation Fee (including first year’s membership fees): $50.00


 * Annual Dues: $40.00
 * Student and Senior Members (no initiation fee): $20.00

Technical Luncheons
CWLS Luncheons and courses qualify for APEGGA Professional Development Hours.

CWLS Student Award
The Canadian Well Logging Society (CWLS) announces yearly awards for engineering and earth sciences undergraduate and graduate students in Canada. The purpose of these awards is to raise interest and awareness of careers in Petrophysics and Formation Evaluation. Formation Evaluation and Petrophysics are the studies of rocks and their fluid properties as they pertain to the	oil and gas industry.

Two $2,000 awards will go to students who submit abstract proposals of a thesis that critically examines some aspects of well logging, formation evaluation or petrophysics. Abstracts should be submitted to the CWLS in their final year of study. The CWLS will select award winners by March 31 of each year. An additional $5,000 will be awarded for the best thesis related to Formation evaluation and submitted to CWLS upon graduation. The final thesis can be submitted at any time in the year of graduation. The award winner will be selected in January of the following year. The winner of this award will be invited at the expense of the CWLS to make a presentation at a lunch meeting of CWLS in Calgary.

Activities
The Society also furthers its objectives by sponsoring symposiums and exhibits.


 * Research committees encourage and support research on relevant problems.
 * The Society is the spokesman to industry and government on topics pertaining to well logging and formation evaluation.
 * The Society holds a monthly luncheon meeting (except July / August) to hear an address on a relevant topics.
 * Each active member will automatically receive the CWLS Journal, ‘InSite’ newsletter and Annual Report.

Publications
The CWLS InSite magazine and the CWLS Journal are seeking articles or papers.

The InSite is intended for short articles to convey ideas quickly in a non-demanding format. If you have an observation, or technique that you wish to convey to the membership, without writing a formal paper, the InSite is a terrific avenue. The InSite also can be used to inform the membership of upcoming events or just the general activity in the formation evaluation community.

The CWLS Journal is published every two years. It contains formal papers for those interested in formation evaluation. If you have a paper which would be of interest to the CWLS membership, please contact either Jeff Dickson or Joelle Meulenkamp. We are especially interested in papers that have specific application to Canadian formation evaluation.

LAS -- Log ASCII Standard
This LAS information site provides links to the File Specifications of the various versions of LAS, plus links to LAS Software. LAS versions 1.2 and 2.0 were written and maintained by the CWLS as public domain well log data formats. LAS version 3.0 was written and is maintained in the public domain by the LAS 3 Committee. You are free to use and distribute these data format Specifications and related Software provided you recognize the ownership of LAS 1.2 and LAS 2.0 Specifications and Software belong to CWLS, and ownership of LAS 3.0 Specifications and Software belong to the LAS 3 Committee.

The following links are presented in two groups: LAS Specifications, and LAS Software & Examples. Select a link from the first group to download the file format Specifications for the corresponding version of LAS. Use the second group of links if you want to download LAS 2.0 or LAS 3.0 examples or Software.

The LAS Version 2.0 link in the second group will initiate the download of an Adobe Acrobat 'pdf' file containing the LAS Version 2.0 Specifications updated in July 2009.The documentation includes a number of LAS 2.0 examples.

The LAS Applications Software was designed to perform routine operations on LAS 2.0 files such as correcting LAS files for common errors, conversion from version 1.2 to 2.0, re-sampling, wrapping, un-wrapping, depth conversion, converting text to LAS 2.0, a Certify routine, merging, changing curve mnemonics etc. It was designed for processing large volumes of LAS 2.0 files. The application uses Microsoft ".NET" software and is compatible with Windows XP, Vista and Windows 7.

LAS Version 3.0 Certify is the only LAS Version 3.0 Software available here. This MS Windows compatible application handles LAS Version 3.0 and earlier data files.

The LAS 3 Committee chose to not create an LAS 3.0 version of Reformat, preferring to leave that for commercial software developers.
