STRESS-INDUCED ANISOTROPIC POROELASTICITY RESPONSE IN SANDSTONE (2003)

In this paper are presented measurements of the elastic and poroelastic (both drained and undrained) propertiesof intact Berea sandstone at confining pressures up to 50 MPa and differential stresses from 0 to 120 MPa.Tests were carried out under axisymmetric loading conditions so that the rock developed transverse anisotropy as stress was applied.
