Ven-Chem 208™ is an oil-dispersible, powdered organophilic lignite engineered for superior filtration control in oil base and invert emulsion mud systems. Ven-Chem 208™ is a chemically modified, organophillic lignite and contains no asphalt or asphalt derivatives. Ven-Chem 208™ provides rapid and effective reduction of excessive fluid loss in diesel oil, mineral oils, and high bottom-hole temperatures. Secondary benefits of Ven-Chem 208™ treatments are improved emulsion stability, improved suspension, and more stable rheological properties.
Ven-Chem 208™ is for use in synthetics, oil bases and invert emulsion muds and can be added directly to the system through the hopper. Typical treatment levels are 2-10 lb/bbl depending on the desired level of control, the type of system used, and the bottom hole temperature. Ven-Chem 208™ can be used in many types of systems, such as synthetics, mineral oil muds, diesel muds, 100% oil phase muds, coring fluids and oil base workover and completion fluids. It is compatible with most types of emulsifiers, oil wetting agents and mud viscosifiers in current use.
Ven-Chem 208™ can be used effectively at bottom hole temperatures up to 400° F and applications at even hight temperatures are possible through use of a special “slug treatment” technique. Contact enventives, LLC. for further information.
