US 2021/0079294 A1 · COATED PROPPANT AND METHODS OF MAKING AND USE THEREOF

Abstract

Methods for producing proppants with a fluorinated polyurethane proppant coating are provided. The methods include coating the proppant particles with a strengthening agent, a strengthening agent, and a resin to produce proppants with fluorinated polyurethane proppant coating. Additionally, a proppant comprising a proppant particle and a fluorinated polyurethane proppant coating is provided. The fluorinated polyurethane proppant coating includes a strengthening agent, a strengthening agent, and a resin. The fluorinated polyurethane proppant coating coats the proppant particle. Additionally, a method for increasing a rate of hydrocarbon production from a subsurface formation through the use of the proppants is provided.
