RokDoc Rock Physics

Course Outline:

3 Day Course: Intended for new and intermediate users who require an introduction to RokDoc and the rock physics theories behind the software. Delegates are guided through a typical RokDoc workflow, comprising data loading and QC, predicting missing data with calibrated rock physics models, blocky modeling, log-based rock physics analysis and 2D forward modeling.

This course will cover Gassmann dry rock modeling, elastic log analysis, cross-plotting and well ties. Further analysis is then performed in RokDoc 2D to determine the effects of seismic tuning, fluid substitutions, porosity perturbation and noise.
