Frack Sand in Utah? – Utah Geological Survey

Sand needs to have a high crush resistance because if grains break and produce smaller fragments, those fragments can plug pore space and reduce permeability. The American Petroleum Institute and the International Standards Organization provide standardized test procedures for evaluating frack sand.

Frac Sand Testing - Basics of Frac Sand Testing

Frac sand needs to be very strong. Strength is found using the crush resistance test. The crush resistance test is used to determine a "K Value," which is the pressure at which 10% or more of the sand starts to break into fines. High quality frac sand often has K values of 5K, 8K, 9K. Resin coated frac sand and ceramic proppants have even ...

Crush Resistance – The measure of the strength of a mass of screened, fines-free dry proppant to force applied over a fixed cross-sectional area, providing an equivalent stress to the proppant under test. The mass of proppant introduced to the crush cylinder is a function of its Bulk Density and the specified loading of 4.0 lb/cu ft.

The "horsey ride" of frac sand testing – Global Energy ...

Oct 03, 2013· Point is, for me the crush resistance frac sand test is the "horsey ride" of testing. Yes, the weighing out of the sand is an exacting and demanding, sometimes painful process. You see, you have to be precise on the mass to 3 decimal points. A grain of sand weighs about 1 mg, so you are literally adding or subtracting grains to nail the mass.
