Review of Numerous Approaches for Unconfined Rock Compressive Strength Estimation

Most problems faced by practicing of the wellbore stability analysis involve evaluation of rock mechanical properties especially unconfined compressive strength(UCS) of formations,which is one of the major inputs for stability analysis models of the borehole.Different sources can be used to develop rock strength profile along the wellbore which is very essential to plan the mud weight window or bit selection for drilling operation.Using this
