发明名称 DOWNHOLE CHEMICAL DELIVERY FOR OIL AND GAS WELLS
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.

主权项 1. A well treatment material comprising: a non-porous proppant having a first coating and a second coating without an intervening adhesive layer between the non-porous proppant and the first coating; wherein the non-porous proppant is suspended in a fluid, wherein the first coating is selected from the group consisting of guar, hydropropyl guar, carboxymethyl guar, and carboxymethylhydropropyl guar, and wherein the second coating is a friction reducer.
