Compressive strength of rocks PetroWiki

Estimating compressive strength General rock failure criterion can be reduced to a few parameters dependent on lithology m and the uniaxial compressive strength C 0 Lithology is commonly derived during log analysis so m may be estimated Table 1 What is needed still is an initial measure of rock strength provided by C 0 C 0 can be estimated from porosity or sonic velocities but many
