The analytical method uses a poro-elastic model and core-calibrated log-derived rock strength profiles with an empirical effective rock strength factor (ESF). The ESF should be calibrated against documented field sanding observations from wells with credible...

... strength. It has been demonstrated that one can empirically predict the rock strength (UCS range) of rocks from an inspection of core plug samples. A Rock Property Index parameter which combines a number of sedimentary parameters is found to be useful in qualifying or ranking the rock strength (UCS...
