Investigation of Local Weighting Materials as a Substitute To Barite In Drilling Mud Formulation
Abstract: Weighting materials are important components needed to increase the density of drilling mud in order to provide enough hydrostatic pressure to balance abnormalpore pressures. In Nigeria, millions of dollars are spent annually in importing barite to serve this purpose. However, there exists large reserves of weighting materials such as barite, hematite, dolomite, calcite, ilmenite in Nigeria hence the need to investigate the suitability of these materials as substitute for imported …
