Ven-Alk™ is a highly efficient, multi-purpose mud conditioner for water base muds. Ven-Alk™ is a pre-reacted salt produced by the reaction of sodium hydroxide with selectively mined Lignite. Ven-Alk™ is used in water-based 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 circulation density by maintaining suitable flow properties.
