Abstract
Improved methods of coating dry proppant particles with a hardenable resin composition, suspending the coated proppant particles in a fracturing fluid and consolidating the proppant particles after being placed in fractures into high strength permeable masses are provided. As the fractures are formed, a liquid hardenable resin component is continuously mixed with a liquid hardening agent component on-the-fly to form a hardenable resin composition. The hardenable resin composition is continuously coated onto dry proppant particles conveyed from a source thereof on-the-fly to form resin composition coated proppant particles, and the resin composition coated proppant particles are continuously suspended in the fracturing fluid on-the-fly.
