The wide-spread use of pneumatic trailers to transport frac sand to well sites in the U.S. has been the traditional method for many years. However, the amount of sand required per frac job has more than quadrupled in the last five years driving the need to efficiently deliver and store more sand near the well site.

Hydraulic fracturing treatments are primarily focused on pumping proppant (frac sand) deep into a network of shale fractures. Proppant keeps fractures from closing and provides porosity and a permeable path for oil and gas to travel. Without proppant, the fractures close, and the point of the treatment evaporates.

Water and sand mixtures are injected into wells at high pressures to create small fractures in the shale, stimulating the production of oil and natural gas. The frac sand acts as a "proppant" because it props these tiny fractures open, allowing oil and gas to flow out to the head of the well where it can be captured and later refined.

What Is the Role of Frac Sand? Frac sand plays an important role in the process of fracturing the shale to release natural gas, oil, and natural gas liquids from pores in the rock. When the high-pressure water stream forces the small perforations to become larger fractures, frac sand holds these fractures open to continue releasing fossil fuels.

What is frac sand? Frac sand is quartz sand of a specific grain size and shape that is suspended in fluid and injected into oil and gas wells under very high pressure. The fluid pressure opens and enlarges fractures as well as creates new ones. Sand grains are carried into these fractures and prop them open after the fluid is pumped out.

To get at the gas, producers must inject water laden with tiny grains of sand (known as frac sand) into their wells to fracture the shale and release the gas. Currently, however, there are no local sources of this specialized sand and it must be imported from Alberta, Saskatchewan, or points farther away at a cost of about $250 to $300 a tonne.
