Crain's Petrophysical Handbook - Special Cases -- Laminated .

Assume a laminated shaly sand with horizontal bedding, a vertical borehole, and a logging tool that can measure both vertical and horizontal conductivity: 1. CONDhorz = VSHavg * CONDshale + (1 - VSHavg) * CONDsand 2. RESvert = VSHavg * RESshale + (1 - VSHavg) * RESsand 3. REShorz = 1000 / CONDhorz 4.

Sand casting - Wikipedia

Sand can be ground, swept or strickled into shape. The metal to be cast will contract during solidification, and this may be non-uniform due to uneven cooling. Therefore, the pattern must be slightly larger than the finished product, a difference known as contraction allowance. Different scaled rules are used for different.

Oil Shale vs. Shale Oil: What's The Difference? – Utah Geological .

To keep the natural and new artificial open fractures from closing due to the pressure of the overlying rock layers, sand or other materials of various sizes (called proppant) is also pumped into the fracture zones to provide porous pathways for fluid flow. With the advent of horizontal drilling, several new Cane Creek shale oil.

Horizontal capacity of skirted circular shallow footings on sand .

Each increment was kept constant till no significant change occurs in settlement, that is to say the difference between two successive readings is less than 0.01 mm per 5 min for three consecutive readings. The load was applied horizontally at 10 mm above the formed sand surface. The horizontal and the vertical.
