Hydraulic fracturing is used in the oil and gas industry to increase the flow of oil and/or gas from a well. The producing formation is fractured open using hydraulic pressure and then proppants (propping agents) are pumped into the oil well with fracturing fluid to hold the fissures open so that the natural gas or crude oil can flow up the well. The proppant size, shape, and mechanical strength influences the integrity of the newly created fractures, and therefore the flow of oil and gas out of the well.
Frac sand is used as a proppant throughout the hydraulic fracturing drilling process. As you can probably guess, pumps will eventually be turned off during the process. The fractures deflate to a degree, but cannot permanently close due to the tons of frac and grain sand within the well.

New fractures in the grain are held open by durable sand grains that form a network of pore spaces that allow fluids to flow freely through the rock into the ground. Frac sand is a critical agent throughout the process and is known as a proppant because the materials props open the fractures when pumps aren’t operating.
Although frac sand is the most commonly used proppant for most fracing companies, other materials like aluminum beads, ceramic beads, and sintered bauxite can be used. Frac sand typically delivers the highest quality performance and is the top choice for most petroleum businesses.
