Document Type : Review Article


Department of Chemical Engineering, University of Port Harcourt, Port Harcourt, Nigeria


The authors reviewed the global technologies for baryte processing, and highlighted its potential application in meeting global standards with emphasis on Nigeria. Baryte (BaSO4) an exceptional industrial mineral has various applications based mostly on its physical properties. Over 80% of the world’s baryte is applied as a weighting agent in drilling fluids. Nigeria has an estimated reserve of over 20 million metric tons .of baryte ore scattered in different parts of the country, yet loses over ₦5billion annually in foreign exchange to the importation of baryte by the oil and gas companies (IOC) operating in the country. Presently, the total national demand for barytes in Nigeria is estimated at 10,000,000 ton per annum. The IOC’s import baryte, on the grounds that the locally produced baryte has lower quality compared to the imported baryte. The Nigerian Content Development and Monitoring Board (NCDMB) has currently approved the implementation of a set of measures geared towards enforcing a ban on the use of imported baryte and drilling fluids in the Nigerian Oil and Gas Industry in line with the provisions and aspirations of this Guideline and the NOGICD Act of 2010. Such measures are design to bring about an optimal production and huge patronage of locally produced baryte in oil and gas operations within Nigeria.
