Technical and general interest articles about well log analysis, petrophysics, and petrophysical software development are listed below. All FREE publications were originally published in a technical journal or newsletter and have a button. These documents are in PDF format.

To provide a complete bibliography, Crain's Reference Manuals and Crain's Integrated Petrophysical Self-Study Video Courses have been added. These are NOT free downloads but can be purchased for a modest fee. Click the  button to see more information on that item.

Software documentation manuals, newsletters, marketing brochures, and minor magazine and newspaper articles are not included.

Special Note: Two published SPE papers on analysis of shale gas were copied directly from my prior work without permission. These are not included on the list, even though my name may appear on the title pages.
