Abstract: A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.

Abstract: An epoxy oligomerization catalyst can be employed to prepare an epoxy resin employing a method including admixing a first epoxy resin having a first epoxy equivalent weight of from about 100 to about 600 with a diphenolic compound, and a catalyst, thereby forming a second epoxy resin having a second epoxy equivalent weight of from about 200 to about 10,000; wherein the catalyst is a guanidinium catalyst. The second equivalent weight is greater than the first equivalent weight.
