Effect of the Type of Pretreatment on the Uniaxial Compressive Strength of a Rock Core Sample

Resumo

Uniaxial compressive strength measurements were made on different artificial rock core samples with different mineral compositions, particle size distributions, permeability, void ratio, and other parameters and subjected to different types of pretreatment. Poisson’s ratio and the elastic modulus of the samples were measured. It was established that the best method for preparing the sample for the measurements is to saturate with water under vacuum and then heat the oil and gas under pressure, simulating formation pressure.
