In this study, effects of six bentonites on the viscosity and filtration loss characteristics of water-based drilling fluids have been investigated. Rheological properties of the drilling fluids prepared by API standards were determined by using high temperature (0-100 degrees C) rotational viscometer. The filtration losses of these drilling fluids were measured using high temperature (0-232 degrees C) and high pressure (0-2000 psi) filtration loss measurement equipment.
