A chemical used in the preparation and maintenance of an oil or synthetic-base drilling fluid that forms a water-in-ollmus sion (invert emulsion). the oil mud emulsifier lowers the interfacial tension between oil and water, which allows stable emulsions with small drops to be formed. Historically, the oil mud emulsifiers have been classified as primary and secondary. Secondary emulsifiers are generally not used alone to make a stable oil mud. These emulsifiers sur round water droplets, like an encapsulating film, with the fatty acid component extending into the oil phase. Emulsifier molecules that cannot fit around drops form clusters (micelles) in the oil phase of adsorb onto solids. The Oil mud emulsion drops each behave like a small osmotic cell. The emulsifier around the drops acts like a semi-permeable membrane through which water can move but ions cannot pass. Thus, oil muds have a special capability (which water muds do not have) to control water transfer to and from the drops simply by adjusting salinity within the water phase of the oil mud
The company manufactures a range of oil mud emulsifiers which have been classified as primary and secondary.
The Pri.Emulsifier is a formulated blend of emulsifiers for use as a primary emulsifier in the invert drilling mud system
The Pri.Emulsifier is a liquid blend of selected primary emulsifiers. It is used to emulsify water into oil in oil/diesel-based drilling fluids. It provides excellent emulsion stability and acts as a wetting agent, gelling agent, and fluid stabilizer in a mineral oil base. It is also used for filtration control and for temperature stability
The Primary Emulsifier is an inverted mud primary emulsifier. It is designed to improve the oil-wet ability to drill solids and increase the stability of the oil mud by primary emulsification between the liquid phases. It assists the performance of the inverted emulsifiers by encircling each solids particle with an oil layer, hence preventing emulsion breakdown due to solids water wetting, thereby keeping stability high
The Pri.Emulsifier should be applied as a primary emulsifier to provide mud stability (as measured by fluid loss and ES reading).
The levels of the Pri.Emulsifler used is a function of required performance in terms of temperature. It is sufficient to give a stable emulsion and provide a good base for the secondary emulsifier to do the tuning. The use of the Pri.Emulsifier will provide the stability of the mud, and tighten the control of fluid loss, as well as imparting high oil-wetting ability. When drilling through magnesium formation, the use of an emulsifier for the Pri Emulsifier range is required to give stable fluid properties under bottom-hole conditions.
The Pri.Emulsifier produces stable emulsions which are resistant to high temperatures and to contamination.
The Pri.Emulsifier imparts good fluid loss properties to the mud. Lime is required to fully activate the emulsion and provide tight fluid loss control. It is recommended that PEMUL be used in conjunction with the Pri.Emulsifier toproduce inverted muds that have excellent emulsion stability with a variety of base oils.
The Pri.Emulsifier is used as a primary emulsifier providing Excellent and very Stable Emulsion and oil wetting agent. It contributes to temperature stability and HTHP filtration control and is most effective over a wide range of temperatures and also in the presence of contaminants. It provides viscosity and filtration control and temperature stability
The Pri.Emulsifier is packaged in 220 Lit polyethylene or steel drum. Customized packaging is also available on request.
The Pri.Emulsifier stored in a dry, well-ventilated area. Keep the container closed. Keep away from heat, sparks, and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink- wrapping and/or stacking
The Pri.Emulsifier has a shelf life of at least six months from the date of manufacture when stored in the original sealed containers in a cool and dry place.
The Pri.Emulsifier must be handled as an industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS.
