United States Patent Application 20130196884

Abstract

A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use a proppant that is coated with at least two chemicals, where each of those chemicals are useful in treating a well. By coating at least two chemicals onto the proppant the amounts of chemicals required to treat a well are reduced by delivering the chemicals to only the areas that require treatment. Additionally mixing issues are avoided as only a single proppant or substrate is used in the well.
