The “PIK-UZ-UES” installation for studying electrical and elastic core properties at reservoir conditions

The PIK-UZ-UES installation is designed to measure propagation velocity of longitudinal and transverse acoustic waves in rock samples in accordance with GOST 21153.7-75 and core samples electrical resistivity at reservoir conditions in accordance with GOST 25494-82. The dynamics of sample porosity is estimated by the volume of released fluid with a change in crimping pressure. The installation software automatically calculates the dynamic Young’s modulus and Poisson’s ratio.
