Improved methods and compositions for coating 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 permeable masses are provided. These methods and compositions are especially suitable for low temperature well, specifically those around the 60° F. to 250° F. ranges. Preferably, a liquid hardenable resin component is mixed with a liquid hardening agent component on-the-fly to form a hardenable resin composition. The hardenable resin composition is coated onto proppant particles on-the-fly that are conveyed from a source thereof to form resin-coated proppant particles in real-time. The resin-coated proppant particles are suspended in the fracturing fluid to be utilized down hole.
A method of making high-strength permeable packs in a fracture created in a subterranean zone having a temperature from about 60° F. to about 250° F. comprising the steps of:
A method of on-the-fly mixing of a hardenable resin composition and a proppant comprising the steps of:
A two-component hardenable resin composition to be activated at the well site comprising:
A liquid hardenable resin component comprising butyl lactate, butyl glyceryl ether and bisphenol A epichlorhydrin.
A liquid hardening agent component comprised of a cycloaliphatic amine, a silane coupling agent, and a surfactant.
