A Premium Single Sack seepage loss additive, surface modified with a liquid lubricant.
Ven-Lube II™ is a nonpolluting, solid, drilling fluid lubricant for use in water base mud systems. It is based on a special, environmentally safe lubricant that has been pre-adsorbed on micronized cellulose fibers. This unique product allows the lubricant to be carried to and concentrated in the wall cake as the fibers are filtered. The fibers provide the additional property of seepage loss control in low pressure depleted sands where differential sticking tendencies require good fluid loss/seepage loss control and lubricity. The use of Ven-Lube II™ minimizes the amount of free liquid lubricant needed in the mud system.
