	There are several different types of materials used as proppant. The first of these types is known as '''frac sand''', and is simply a high-purity quartz sand with durable, round grains. As a result of its strength it is crush-resistant, and ~~thus is~~ effective as propping open cracks made in the ground during the hydraulic fracturing process.

			Other types of proppant materials include resin-coated sand and ceramic proppants. Resin-coated sand is simply sand that is coated in a resin material to smooth the surface of the sand and make the shape more uniform. Along with this, coating the sand in resin increases its strength, making it more desirable as a proppant. Finally, ceramic proppants are the most uniform in shape and the strongest of the proppants as their manufacturing is entirely controlled. The uniform shape of this type of proppant ensures that there is more space for the oil and gas to flow through the proppant material and out of the well.<ref>CARBO. (January 9, 2015).

			==Size and Shape==
			Proppants come in a variety of different grain sizes, as well as different shapes. The size and shape of a proppant is important as it influences the final [[permeability]] in the induced fracture. Frac sand (or naturally occurring sand-type proppant) is generally irregular in shape, although this depends on the source. Compared to other types of proppants it has lower strength and packs together closely in fractures, resulting in a less permeability when compared to other proppant types. Resin-coated sand is more smooth and round in shape, and is also stronger than traditional frac sand. As a result of this shape and texture, resin-coated sand does not pack as closely together, therefore is more permeable than frac sand. Finally, ceramic proppant is the most uniform shaped and most round proppant. It has a high strength, and as a result of its properties it is also very permeable, allowing trapped oil or natural gas to flow easily out of the fractures.<ref>Horiba. (January 9, 2015).
