... indicate that the artificial cores are similar to the natural sandstones. The proposed method can be used to produce synthetic sandstone samples with weak to moderate strength for sand production experiments or related topics in rock mechanics. Introduction Sand production is a common concern in weakly...

... sandstones made from sintered glass beads for most of our measurements. We also made measurements using a natural sandstone, and investigated the effects of clay and of undersaturation. BACKGROUND AND METHOD Skempton's coefficient B is defined as the change in pore-fluid pressure Pf with change...
