The Firebag Property’s main deposit type is silica sand, or frac sand.
Silica sand, frac sand or proppant (i.e., propping agents) is a durable, round-grained, crushresistant material produced for oil and gas hydraulic fracturing, otherwise known as fracking. Fracking is used in the oil and gas industry to increase the flow of oil and/or gas from a well. Using hydraulic pressure, the producing formation is fractured open, and then proppants are pumped into the well with fracturing fluid to hold the fissures open so that the natural gas or crude oil can flow up the well. The proppant's size, shape and mechanical strength influence the integrity of the newly created fractures, and, therefore, the flow of oil and gas from the well. Billions of frac sand grains are carried deep into the fracture, and it can take up to four million pounds of sand to frack a single well.
The size range of the frac sand is very important. Typical sand sizes are generally between 8 and 140 mesh; some examples include 16/30 mesh, 20/40 mesh, 30/50 mesh, 40/70 mesh or 70/140 mesh. A controlled range of sizes and favoured spherical shapes will lead to greater conductivity.
The overall Quaternary sand deposit is characterized as follows:
- laterally extensive;
- generally consistent to depths exceeding 24 m;
- high in silica content; and
- indicative of frac sand quality as evidenced by rain size and roundness.
