Abstract

Laboratory experiments were designed to measure Skempton coefficient B for Dunnville sandstone using small and large specimens.The pore volume V_p of the small specimen was on the same order as the system volume V_l, while V_p of the large specimen was 100 times V_l.The large specimen provided a direct measurement of B.For Dunnville sandstone, Skempton coefficient B calculated with the appropriate poroelastic model and material parameters agrees with the measured B.
