A proppant for hydraulically fracturing a subterranean formation, said proppant comprising:
- A. a particle;
- and
- B. a polyamide imide coating disposed on said particle in an amount of from about 0.5 to about 7.5 percent by weight, based on 100 parts by weight of said particle.
A method of forming a proppant for hydraulically fracturing a subterranean formation, said method comprising the steps of:
- A. providing a particle;
- B. providing a polyamide imide coating;
- and
- C. coating the particle with the polyamide imide coating particle in an amount of from about 0.5 to about 7.5 percent by weight, based on 100 parts by weight of the particle.
A method of hydraulically fracturing a subterranean formation which defines a subsurface reservoir with a mixture comprising a carrier fluid and a proppant, the proppant comprising a particle and a polyamide imide coating disposed on the particle in an amount of from about 0.5 to about 7.5 percent by weight, based on 100 parts by weight of said particle, said method comprising the step of pumping the mixture into the subsurface reservoir to cause the subterranean formation to fracture.
