Ven-K™ is a highly efficient, multipurpose mud conditioner for water base muds. Ven-K™ is a prereacted salt of potassium hydroxide and lignite. Ven-K™ is primarily used as a fluid loss additive and shale control additive in potassium base shale control systems.
Ven-K™ is also used in water base muds to (1) reduce viscosity and gels in order to maintain desirable flow properties; (2) improve aging characteristics in high temperature fluids by controlling fluidity; (3) reduce high pressure, high temperature filtrates and provide tough, thin filter cakes; (4) thin and emulsify oil-in-water or liquid lubricant containing fluids; (5) reduce effects of contaminants; and (6) control the equivalent circulating density by maintaining suitable flow properties.
Ven-K™ can be used to thin almost all types and densities of water base drilling fluids. It is particularly designed for use in potassium base shale control systems. In addition, it will function as an effective emulsifier in oil-in-water muds and will provide some emulsification and dispersing properties for liquid lubricants. Ven-K™ is effective as a hightemperature filter loss additive in water base mud systems.
Approximately 1-3 lb/bbl of Ven-K™ is usually required to produce optimum thinning of water base muds. When Ven-K™ is being used to emulsify oil or liquid lubricants in water muds,concentrations of 2-6 lb/ bbl are common. High temperature (above 350°F) filtration control can require 6-10 lb/bbl or more of Ven-K™. The actual concentration required depends on the mud system, bottom-hole temperature, and other factors.
