Primary Emulsifier for Oil-Based Mud

UTMUL-P is a primary emulsifier for oil-based drilling fluids. Developed with a well-designed formulation, it delivers excellent emulsifying performance, improves the thermal stability of invert emulsion fluids, and reduces high-temperature and high-pressure (HTHP) fluid loss.

A series of oil-based mud tests with different base oils, mud densities, oil-water ratios and hot rolling temperatures have verified that under the operating temperature of no more than 177°C (350°F), UTMUL-P enables drilling fluids to maintain desirable rheological properties, high electrical stability and low HTHP fluid loss.

UTMUL-P is applicable to various oil-based drilling fluids, including diesel oil-based, white oil-based and synthetic-based systems. It features low toxicity, zero fluorescence, and excellent compatibility with other oil-based drilling fluid additives.
