Support material for hydraulically fracturing a subterranean formation, method for forming a support material for hydraulically fracturing a subterranean formation, and method for hydraulically fracturing a subterranean formation.

摘要

Support material for hydraulically fracturing a subterranean formation, method for forming a support material for making hydraulically a underground formation, and method for hydraulically fracturing a subterranean formation a support material includes a particle. A polymeric coating disposed around the particle.The polymeric coating comprising a reaction product of a polyol, an isocyanate, and a (azole. The polyol has an average molecular weight (number of from about 200 to about 1000 g / mol, a training method of the support material comprises the steps of providing the particle, arrange the polyol (providing the isocyanate, and provide the azole.The method also includes the steps of combining the polyol (isocyanate, and the azole to react and to form the polymeric coating and coating the particle with the polymeric coating to form the support material.
