This course provides an introduction to RokDoc GeoMechanics and Image Logs functionality, as well as a brief introduction to PressureView.

This new course takes RokDoc users through the workflow and tools for 1D geomechanical modeling in RokDoc and show how to Build and calibrate a model in 1D, constrain in the Stress Polygon, cross-check predicted results with image logs, and build an offset well plan using RokDoc 2D.
