Direct and indirect laboratory measurements of poroelastic properties of two consolidated sandstones

Experimental measurements to derive the drained bulk C and the solid bulk Csu compressibility, the poroelastic Biot coefficient α, Skempton coefficient B as well as porosity ϕ were performed under drained, undrained and unjacketed pore pressure conditions. The experiments were conducted for two different kinds of sandstones, Bentheimer and Flechtinger. During all experiments, the confining hydrostatic pressure was continuously increased up to 85...
