..., as an indicator of the variability of rock strength along the length of the core. Rock scratch measurements are limited to rocks with unconfined strengths larger than 100 psi. Furthermore, the core should be well preserved, undamaged and, when of low strength, provided with a supporting sleeve to prevent damage...

... Abstract The temperature effects of high power lasers on rock strength and mechanical properties are presented. It was found that the high temperature induced by lasers drilling through rock enhances porosity and permeability and reduces strength. High temperature causes microcracks, vaporizes...

Abstract A laboratory testing program was performed to investigate the behavior of the sandstone of an HPHT reservoir when subjected to realistic in-situ stresses, pore pressures and stress changes due to production. Volumetric changes, stress path effects, plastic deformation and strength were...
