ut on 05 sandstones and 03 carbonate core samples. The results indicated that hysteresis is severely dependent on depositional texture, and it is directly related to Young modulus and Bulk modulus. Tight rocks exhibited higher hysteresis than friable rocks, due to frictional sliding and grain contact adhesion, which causes permanent damage to pore structure. Porosity displays an inverse relation to hysteresis, as high pore density enables rock’s matrix to deform and recover its shape without frictional sliding and grain contact adhesion.
