Investigating Effects of Cryogenic Treatment on Physical and Mechanical Properties of Geothermal Formation Samples – an Experimental Study

“…Before and after cryogenic treatments, the ultrasonic velocities (P-wave and S-wave) of samples were measured at confining pressures ranging from 750 psi to 4500 psi, with an incremental of 750 psi. The P-wave and S-wave velocities measured before the cryogenic treatment were in the range found in the literature, 15420-16732 ft/s and 8858-10171 ft/s, respectively (Kwon et al, 2019;Rostovtsev, 2019;Stowe, 1969;Wanniarachchi et al, 2017). The ultrasonic velocity of the samples is influenced by the size and number of pores, and number of fractures in the rock.…”
