摘要:
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 mixed with a liquid hardening agent component to form a hardenable resin composition. The hardenable resin composition is coated onto dry proppant particles conveyed from a source thereof to form resin composition coated proppant particles, and the resin composition coated proppant particles are suspended in the fracturing fluid.
