Ven-Chem 222™ is a non-asphaltic, oil dispersible fluid loss additive designed specifically for oil muds and invert oil mud systems. Ven-Chem 222™ is a high performance fluid loss additive based on chemically modified, organophilic lignite. Ven-Chem 222™ is specifically designed for high temperature, oil base mud systems. It provides rapid and effective reduction of excessive fluid loss in diesel oil, mineral oil and synthetic-based systems. Ven-Chem 222™ treatments generally provide some secondary benefits such as improved emulsion stability, increased tolerance to contamination, and more stable rheological properties.
Ven-Chem 222™ is recommended as an HTHP fluid loss additive for oil based, synthetic based and invert oil mud systems, particularly where bottom hole temperatures exceed 400°F. If lower temperatures are encountered, better cost/performance might be obtained with Ven-Chem 208™ or Ven-Chem 215™. Typical concentrations vary from 2 lb/bbl to 20 lb/bbl.
Ven-Chem 222™ can be added directly to the mud system through the hopper. Actual concentrations of Ven-Chem 222™required will depend on the type of system used, type and concentration of emulsifiers, type of oil, mud weight, type of gelling agent, temperature conditions, etc.
