Rheological Additive Oil Based High-Temperature Viscosifier

BENTONE 42 is a specially designed organoclay, which was chemically engineered to maintain product performance when subjected to temperatures as high as 450ºF for as long as 600 hours. Additionally, as temperature increases, the viscosity profile at temperature remains flat and minimizes the tendency for barite sag while improving cuttings transport and hole cleaning.

Key Properties

• Stable to bottom hole temperatures in excess of 450ºF • Flat rheology with increasing temperature for antisag and improved carrying capacity • Shear thinning rheological profile for improved ROP • Optimized for use in synthetic oils • Tolerant to salt, high lime, cement and drill solid • Efficient hole cleaning and suspension properties • Environmentally acceptable
