Definition - What does Proppant mean?

Proppant is a solid material that is designed to keep a hydraulic fracture open during treatment. It is usually sand grain or a man-made proppant that includes high-strength ceramic materials like resin-coated sand. The materials should be chosen carefully as they should be permeable to gas so as to withstand the closure stresses and prop the fractures. Proppants can be sorted by their size and sphericity. They also provide a channel for production of fluid. Moreover, a suitable Proppant has a positive impact on the output rate of a well.

Petropedia explains Proppant

Sand is the most commonly used Proppant due to its small configuration. It is of two types, large mesh proppants, and small mesh proppants. Large mesh proppants have higher permeability than small mesh proppants. The mesh size is essential because it affects the fracture length as it is deposited in the fracture thus can resist the fluid flow or further growth of the fracture. Besides, it helps in understanding the fluid dynamics and rheology of the fracturing fluid. The Proppant geometry helps in understanding the shapes of the Proppant that affect the strength, density, flow rate and viscosity of the fluid economically and environmentally.
