Abstract:
Spherical and rod-shaped proppants and anti-flowback agents made from flash calcined clays, such as flash calcined kaolin, possess high strength and high conductivity. The starting material may optionally be milled to achieve better compacity and crush resistance in the final proppant or anti-flowback agent. A fracturing fluid may include the rods or spheres alone, or in combination with each other or other proppants or anti-flowback agents of different shapes.
