RokDoc GeoPressure Calculators - 1 Day Course - Training Course by Ikon Science

RokDoc GeoPressure Calculators - 1 Day Course

Available as a public course
Available as a private in-house course

This course introduces the attendee to the basics of the GeoPressure Calculator (GPC) and Fracture Pressure Calculator (FPC) modules within RokDoc.

Using datasets from the Gulf of Mexico the course introduces some of the basic concepts of overburden calculation, pore pressure prediction and fracture pressure calculation, but is not intended to be a comprehensive introduction to the often challenging field of pore pressure prediction in shales. The course outlines the background theory of predicting pore pressure in shales and then proceeds to demonstrate these using the GPC and FPC applications. Although no previous experience of using RokDoc is required, it is advantageous.
