Profile: Xinjiang Becken Energy Engineering Co., Ltd.specializes in the research, development, production, and sales of oilfield chemical products. FH-1 is the sulfonate of petroleum asphalt with quite strong temperature, calcium, and salt tolerance. It can block wall micro-cracks, and adhere to well walls to form thin and tough compressible mud cakes. FH-1 is applicable to various drilling liquid systems, with an effect of filter loss and collapse resistance. It can improve the quality of mud cakes, inhibit the dispersity of drill cuttings, and prevent instability of drilling liquid viscosity caused by shale hydration.
