Of generally uniform shape and material, frac sand is utilized in the petroleum industry for the process of hydraulic fracturing, from which it gets its name. Unlike conventional sand, frac sand is made entirely of quartz and is crush-resistant, making it ideal for use in the process.
Frac sand and its equivalent material (proppants) make hydraulic fracturing possible and play a key role in freeing oil and gas that has accumulated in impermeable rock (that is, rocks with pores so small that oil and gas cannot flow). The grains of frac sand are flushed into cracks made by water pressure into nonporous oil-bearing rock to prevent them from closing. This process allows petroleum and natural gas that had previously been trapped in the rock to flow out.
The frac sand is carried to its destination through the action of water piped in high pressure and delivered straight through the cracks made in the rock. The water itself is often aided by thickeners that turn the fluid into a gel more capable of delivering the sand to the cracks.
A large volume of frac sand is needed to keep a hydraulic fracturing project running. In general, the more sand used in the operations, the better the extraction of the oil at a significant reduction of cost to the producers. A steady supply of good quality frac sand can boost productivity while keeping overhead costs low.
Having started in the frac sand industry, the founders of Foster Frac, LLC have since diversified into trucking and freight. Visit this Facebook page for more information on the company.
