Introduction
A chemical used in the preparation and maintenance of an oil or synthetic-base drilling fluid that forms a water-in-oil emulsion (invert emulsion). An oil mud emulsifier lowers the interfacial tension between oil and water, which allows stable emulsions with small drops to be formed. Historically, 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 surround 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 or adsorb onto solids. 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. Our company produces a wide range of drilling fluid emulsifiers called primary and secondary emulsifiers.
The Sec.Emulsifier is a proprietary surfactant blend for use as a secondary emulsifier in invert drilling mud systems.
The Sec.Emulsifier is a liquid blend of selected secondary emulsifier and wetting agent. 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 Sec.Emulsifier is a secondary invert emulsifier based on a chemically modified. The Sec.Emulsifier’s oilsoluble, water dispersible, and is compatible with most products employed in oil-based drilling fluids.
The Sec.Emulsifier uses diesel alcohol solvent, but can be formulated in low toxic solvent for more environmental control and is coded as Sec.Emulsifier, the Sec.Emulsifier when used in conjunction with the Sec.Emulsifier will give stable invert mud that eliminates or reduces the need for additional fluid loss control additives.
The Sec.Emulsifier is both a secondary emulsifier and an oil-wetting agent suitable for use in diesel oil-based drilling fluid systems. The Sec.Emulsifier has minimal alkalinity requirements. When the Sec.Emulsifier is used in conjunction with the Sec.Emulsifier , high temperature stable invert emulsions with low filtration rates can be obtained.
The Sec.Emulsifier functions as a secondary emulsifier, Additional benefits include improved thermal stability and HTHP filtration control. The Sec.Emulsifier wetting agent is effective over a wide temperature range, in the presence of contaminants, and reduces the adverse effects of water contamination.
Applications
The Sec.Emulsifier is used as a secondary 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 filtration control and temperature stability.
The Sec.Emulsifier is an excellent emulsifier for water in oil drilling fluids and may be used with a variety of brine emulsions.
The Sec.Emulsifier is designed to improve the stability of emulsions aid in gel strength control and improve the fluid loss characteristics of drilling fluids.
The Sec.Emulsifier exhibits excellent performance with regard to the range of temperatures and contaminants.
The Sec.Emulsifier can be employed as a single Emulsifier; however, it is usually recommended that it be used in conjunction with the primary emulsifier such as this product or a wetting agent.
The Sec.Emulsifier is a concentrated secondary emulsifier used for formulating invert drilling fluids. It will provide high emulsification and good oil-wetting properties. The-Sec.Emulsifier is commonly used with primary mud emulsifiers such as the Sec.Emulsifier.
The Sec.Emulsifier offers emulsion stability as well as high-temperature tolerance and resistance to contamination
The Sec.Emulsifier does not require lime, however the use of lime will enhance the emulsion stability and the HTHP Fluid Loss Mix according to standard mixing procedure. A primary emulsifier is required to form a stable emulsion.
The Sec.Emulsifiers promote oil-wetting in invert emulsion systems.
The Sec.Emulsifiers improve electrical stability measurements.
The Sec.Emulsifiers reduce the flow properties of invert emulsions.
The Sec.Emulsifier additive functions as the wetting agent and secondary emulsifier, when used in combination with the Sec.Emulsifier.
The Sec.Emulsifier additives preferentially wet barite and drill solids to prevent water wetting of solids Secondary functions include: improving thermal stability, theological stability, filtration control, and emulsion stability as well as improving a system’s resistance to contamination.
