Abstract

Numerous correlations exist to determine rock strength of various lithologies. Rock strength information is used in the prediction of in-situ rock behavior and allows for proper determination of casing design, perforation zones and in the stability of formations. However, almost all of the correlations developed are site specific and applications in fields outside the sampled area are questionable and unguaranteed. As such, there is no field wide accepted correlation used to determine rock strength. This research focused on first identifying formation specific correlations and applying a statistical approach to determine expected rock strength. Effects of various lithological combinations were established. The methods were applied to an actual field case in the Mid-Alberta basin in an attempt to ascertain its accuracy.
