The President of the Petroleum and Natural Gas Senior Staff Association of Nigeria, PENGASSAN, Festus Osifo, has explained that the country’s refineries were shut down due to inefficiency rather than being completely non-functional. “The refineries were shut down not because they were not working, but because the material balance was poor. For instance, if crude worth about $10 million was supplied, the refined products coming out were valued at about $9.5 million. “I listen to those that said it never worked, which is not correct, the refinery worked. That was exactly what happened, not that the refineries were not working.”Continuing, he said: “We paid a visit to the new GCEO of NNPC Limited, and we put that question to him, that why were the refineries shut down?
