RokDoc Reservoir Characterization - 2 Days Course

Sign up for this event

Course Outline:

Intended for intermediate RokDoc users who require an introduction to Rock Physics Model Templates and RokDoc 3D. Attendees are taken through a series of workflows illustrating the predictive power of rock physics models, before progressing to RokDoc-3D, where the user can model lithologies and fluids, manipulate seismic inversion volumes, create elastic and geological property volumes, and export them to SEG-Y.
