SUREMUL

Primary invert-emulsion system emulsifier

How SUREMUL emulsifier improves wells

SUREMUL primary invert-emulsion system emulsifier provides excellent emulsion stability, preferential wetting of solids by the continuous phase, filtration control, and temperature stability. SUREMUL emulsifier is used in conjunction with SUREWET RHELIANT system invert-emulsion system surfactant. The SUREMUL emulsifier can also be used in other M-I drilling fluid systems as well as the VERSA oil-based drilling fluid systems in conjunction with a secondary emulsifier or a wetting agent.

SUREMUL emulsifier is designed for use as the primary emulsifier in the RHELIANT thermally stable, flat-rheology drilling fluid system to provide a stable emulsion and excellent oil wetting. The emulsifier contributes to HTHP filtration control and to the temperature stability of the system. It is effective over a wide temperature range and in the presence of contaminants. SUREMUL emulsifier exhibits minimal dispersion tendencies when drilling reactive formations.

SUREMUL primary emulsifier is used in conjunction with the SUREWET surfactant in the RHELIANT system to enhance the emulsion characteristics of the fluid. SUREMUL emulsifier can also be used as a primary emulsifier in VERSA systems.
