barite - Schlumberger Oilfield Glossary
Pure barium sulfate has a specific gravity of 4.50 g/cm 3, but drilling-grade barite is expected to have a specific gravity of at least 4.20 g/cm 3 to meet API specifications. Contaminants in barite, such as cement , siderite , pyrrhotite , gypsum and anhydrite , can cause problems in certain mud systems and should be evaluated in any quality assurance program for drilling-mud additives.
Effect of barite and gas oil drilling fluid additives …
25-6-2016 · This research presents a study of the effect of drilling fluid on the reservoir rock properties. The interactions between the clay minerals existing in the formations and the drilling fluids have been studied. Two types of drilling fluids, which are water-based ferrochrome lignosulfonate base mud and lime mud, were prepared for the study. About 100 core plugs were prepared from seven oil wells ...
