LONDON, Aug 27 (Reuters) - Refineries in Nigeria, Africa's
top oil exporter, processed almost no crude oil in the 13 months
to end June, according to the latest data published by the
Nigerian National Petroleum Corporation (NNPC) on Thursday.
In the same period, operating costs for the country's three
main oil refineries, which the NNPC has shuttered pending
revamps, were $367 million.
