Ven-Chem 215™ is an oil-dispersible, powdered organophilic lignite engineered for filtration control in oil base and invert emulsion mud systems. Ven-Chem 215™ is a chemically modified, organophillic lignite and contains no asphalt or asphalt derivatives. Ven-Chem 215™ provides rapid and effective reduction of excessive fluid loss in diesel oil, mineral oils, and high bottom-hole temperatures. Secondary benefits of Ven-Chem 215™ treatments are improved emulsion stability, improved suspension, and more stable rheological properties.
Ven-Chem 215™ is used in oil based, synthetic based, 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 in use, and the bottom-hole temperature.
Ven-Chem 215™ is recommended for use at static bottom-hole temperatures of up to 300°F, although use at temperatures of up to 350°F is feasible in certain instances. The performance is highly dependent on the type oil, the emulsifiers and the wetting agents. For prolonged drilling at bottom-hole temperatures over 300°F, use of either Ven-Chem 208™ or Ven-Chem 222™ is recommended.
