Oilfield drilling

Application of humic acid in oil field drilling

Humic acid is widely used in oilfield drilling fluids as filtrate reducer, shale inhibitor and viscosity reducer. For oilfield drilling:  The products have the functions of filtrate loss reduction, viscosity reduction and collapse prevention, as well as better resistance to salt and high temperature mainly based on the hydrophilicity, complexing ability, as well as adsorption and dispersion capabilities of  its molecular.
