Characterization of barite ores from selected locations in Nigeria for drilling fluid formulation

Barite is a non-metallic mineral composed of barium sulfate and is largely used by the oil and gas industry during drilling operations to control reservoir pressure. According to the American Petroleum Institute (API) standard, the specific gravity of barite should be a minimum of 4.1 to be applied...
