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 .
