    摘要: 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.

    摘要: A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use multiple chemicals that are pre-mixed and then formed into a single solid blended mixture. By forming at least two chemicals into a single solid mixture, the complexity involved in transporting multiple solid or liquid chemicals is avoided. If the solid chemicals were merely premixed they would tend to segregate during shipping, handling, and storage altering the concentration of the chemical mix as it is pumped downhole. Simply having less equipment on the wellsite increases the accuracy of the well treating process and decreases the likelihood of a time consuming and thus costly delay due to equipment failure.
