Crushing characteristics of four different proppants

2018-5-1 · Genoa sand exhibits more grain crushing than Jordan sand, while resin-coated sand and ceramic proppant experienced only minor fracturing at compressive stresses of 40 MPa. The grain shape and size distribution measurements were used to empirically estimate and compare the permeability and fracture conductivity for different proppant packs.

Effects of gradation and grain crushing on the ...

The dynamic behaviors of calcareous sand were investigated under undrained conditions using cyclic triaxial tests, and the results were compared with those of commercially available Fujian (Fj) sand. The test results were used to evaluate the effects of gradation, particle crushing, and other parameters on the liquefaction resistance. The results of the undrained cyclic triaxial tests indicate ...

What is Frac Sand? A Durable Sand for Hydraulic

2017-9-9 · What Is Frac Sand? "Frac sand" is a high-purity quartz sand with very durable and very round grains. It is a crush-resistant material produced for use by the petroleum industry. It is used in the hydraulic fracturing process (known as "fracking") to produce petroleum fluids, such as oil, natural gas, and natural gas liquids from rock units that lack adequate pore space for these fluids to flow ...

2009-2-23 · Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement. The results of a number of direct shear tests are shown in Fig. 8.9. The sand yields a shear stress-normal stress plot similar to that of the sliding block in Fig. 8.7 but the clay gives an

Resistivity - University of British Columbia

2007-6-28 · Resistivity is the resistance per unit volume. Consider current flowing through the unit cube of material shown to the right: resistivity is defined as the voltage measured across a unit cube's length (Volts per metre, or V/m) divided by the current flowing through the unit cube's cross sectional area (Amps per meter squared, or A/m 2 ).
