Cola®Solv TES-M (ME)

Cola®Solv TES-M (ME) is a low HLB (ca. 6), high-performance emulsifier and wetting agent designed to increase emulsion stability in oil-based drilling fluids. Based on Maleniated amidoamines of natural fatty acids and polyamines in base oils, it serves as a workhorse secondary emulsifier for invert-emulsion drilling fluids. Cola®Solv TES-M (ME) demonstrates improved emulsion stability over traditional emulsifiers by reducing high-pressure high-temperature (HPHT) fluid loss. It can function as an emulsifier to offer the fluid stability in the static aging at high temperature 325°F as well as a wetting agent in the high-performance oil-based drilling fluid system. Typically used in conjunction with primary emulsifiers, it ensures excellent emulsion stability, oil wetting of drill solids, and reduction of HPHT fluid loss.

Upon neutralization with alkali hydroxides or alkanolamines, Cola®Solv TES-M (ME) turns into an anionic emulsifier. In addition to its extensive applications in oil and gas, it can also be used as a primary or secondary emulsifier in soluble oil and semi-synthetic metalworking fluids.
