SHARE YOUR SKILL AND KNOWLEDGE
We are looking for some keen knowledgeable contributors to update and add to the content of Crain's Petrophysical Handbook. We are celebrating our 19th year online and it is time for some fresh ideas and new blood to carry on into the future.

There are 400+ individual webpages on this website and we have 40 - 50,000 page views every month. With no advertising and no sponsors to intrude on the content, there is no similar training material available in any discipline, not counting Wikipedia, of course.

Some topics are a little dated and some could use better illustrations or examples. There are also additional topics that could be covered to provide broader background for practicing petrophysicists, engineers, geologists, and geophysicists. Contributions on wireline formation testing, wireline completion operations, production logging, logging while drilling, horizontal well steering, and other similar topics are needed. Induction log data processing, NMR processing and data analysis, image log processing and analysis, ECS inversion methods, acoustic log processing all need a little help. You can probably add to this list.

There are already a dozen or so webpages by Guest Authors. Join them in making CPH the best it can be. There is no direct financial reward but you will get credit on any page that you contribute to.


RULES OF THE GAME
Guest Authors may contribute new webpages to
Crain's Petrophysical Handbook. Associate Editors may edit and update existing pages.

If you wish to make a technical contribution to the Handbook,
Email Me
with an outline and a copy of your resume so I can get to know who you are. I reserve the right to refuse any material without giving any reason.

Submit contributions in MS Word format with embedded illustrations and captions. The final webpage will look as close to this document as is possible.

This is not a Wiki, so all contributions will be edited for clarity and formatted to conform to this website's standards. You may be requested to do some editing or formatting before the contribution is accepted.

Write clearly at a 2nd or 3rd year university level, using your own words. See
Petrophysical Reports for style suggestions.

Use "computer-ready" math, in the style currently used in the Handbook. See
Quantitative Analysis Basics for examples.

Use existing variable names as used on the website. New variable names should conform to the website style. Normally, measured values are all upper case letters (eg. RESD, DTC, KMAX), computed values have both upper and lower case letters (eg. Rt, PHIsc, Perm). Define all variables, even if they have been defined on other pages. See
List of Abbreviations - Petrophysics and  List of Abbreviations - Seismic.

Use generic tool and LAS curve names and minimize the use of tradenames.

Show references inline with the text. Keep them to a minimum.

No external links are allowed except to Wikipedia. Links to related CPH pages may be inline or in a textbox.

Be sure illustrations are your own or public domain or reproduced with permission. All permissions and copyright infringement issues are the personal responsibility of each individual Guest Author or Associate Editor.
