On the Measurement of B for a Sandstone.

Highlights: Laboratory experiments were designed to measure Skempton coefficient B for Dunnville sandstone using small and large specimens. The pore volume Vp of the small specimen was on the same order as the system volume Vl, while Vp of the large specimen was 100 times Vl. 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. [ABSTRACT FROM AUTHOR]
