Session SEVEN - FRACTURED RESERVOIRS
Course Outline and Instruction Materials c. 1978 - 2008 E. R. (Ross) Crain, P.Eng.

Integrated Courseware Connecting Logs, Cores, Tests, Productivity, Cash Flow, and Seismic Petrophysics - Since 1973

Students in this class will have varied experience with logs, but need a clear understanding of fractured reservoir analysis concepts to enhance their job skills. This seminar is supported by "Crain's Fractured Reservoirs" (80 pages) reference manual and exercises, a high quality PowerPoint presentation, and 1 day of instruction.

DESIGNED FOR: Anyone who works with logs in fractured reservoirs, or who wants to do more with their logs, or who works with other people who use logs:

SUMMARY: This semi-quantitative course covers all topics needed to use logs for fracture location from conventional open hole logs, as well as calculation of fracture intensity, fracture porosity, fracture related porosity, matrix porosity, water saturation, and permeability. The use of dipmeter analysis and image logs as well as integration and calibration to core data is stressed.
