Product Description
SF can reduce viscosity effectively. It can keep stability of borehole and its effective period is long after the mud is maintained with SF. It can perform deflocculating, lubricating and defoaming property. SF can improve borehole stability through preventing filtration invading to formation. It is a kind of non-toxic and non-environment-pollution product. It can be directly added into various water-base drilling fluids. Its recommended dosage is 0.5 – 2.0% (v/v).
