The 20 or so web pages in this Chapter of Crain's Petrophysical Handbook cover much the same content as a Video Course for CEOs, geoscientists, engineers, and petrophysicists looking to improve their oil-finding skills.

This includes basic definitions, the analysis model, Crain's Rules for visual log analysis, common mathematical algorithms
with usage rules and recommended parameters. The only thing missing is the dulcet tones of my voice and the video slide show. See the menu at the right for the complete topic index for this course.

To benefit from this course, you should practice with some real data, as well as read the text. Here are three Exercises to check out your skill set:

EXERCISE 1: CLEAN and SHALY SANDS with OIL and WATER
EXERCISE 2:
DOLOMITIC SAND with OIL and ANHYDRITE CAP
EXERCISE 3: DOLOMITE REEF with GAS, OIL, and WATER

Each exercise has raw data and answer depth plots, a visual analysis, well history, core data, and other useful info typical of what might be found in your well files. A spreadsheet analysis using "META/KWIK" is provided for each exercise (see next Section on this webpage).

Other case histories that can be used for practice are in Chapter 18..

A kit containing LAS log data files for these and 7 other examples, including full-size raw data and answer plots, core data listings, and other useful stuff, can be purchased HERE so you can test your existing software or any user defined equations you have created from the models described in this Chapter.

Spreadsheet software provides the fastest method for quantitative petrophysical analysis of conventional oil and gas reservoirs. By converting "Crain's Rules" into mathematical form, and adding more sophisticated algorithms for water saturation, permeability, productivity, and reserves, we can perform a complete analysis in less than half an hour.
