RokDoc Ji-Fi - 3 Days Course

Sign up for this event

Course Outline:

RokDoc Ji-Fi (Joint Impedance & Facies Inversion) is our most innovative inversion technology. This course takes you through detailed workflows; starting from the generation of facies logs, through to running the inversion and QC of the results, so you fully cover all its extensive capabilities. As well as learning how to drive the software, all relevant underlying principles are discussed, and results reviewed.
