Ven-Rez I™ is a chrome-free resinated lignite derivative engineered with a potassium ion to provide improved filtration control and stabilize rheological properties in high temperature water base muds while providing increased levels of shale inhibition and stabilization. Ven-Rez I™ is based on a new lignite derived resin. It is compatible with most water based drilling mud additives.
Ven-Rez I™ can be used to thin almost all types and densities of water based drilling fluids. 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-Rez I™ can be used to stabilize salt-contaminated muds.
Ven-Rez I™ is particularly effective as a high temperature filter loss additive in water based systems. Approximately 0.5-2.0 lb/bbl Ven-Rez I™ is usually required to produce optimum thinning of water based muds. If sufficient alkalinity is not present in the mud, it may be necessary to add up to 0.5 lb/bbl or more of caustic soda.
