Baird-McClure Pore Pressure School
Course Outline: Pore Pressure & Frac Gradient Prediction
Baird Petrophysical International, Inc.
The Baird-McClure Pore Pressure School is a combination of the McClure geological approach, the Pilkington petrophysical approach and Baird's refinement's from personal hands-on experience with over 2000 wells. There is no better source of knowledge for pore pressure prediction for well planning and for prospect (hydrocarbon) pressure seal integrity analysis.
