West Africa's oil exports due for loading next month have struggled to sell, due to weak demand from the region’s regular customers in Asia and Europe and tougher competition from rival suppliers. (Bloomberg) -- West Africa’s oil exports due for loading next month have struggled to sell, due to weak demand from the region’s regular customers in Asia and Europe and tougher competition from rival suppliers. As much as half of Nigeria’s planned crude loadings for May haven’t yet found buyers, according to oil traders specializing in West African grades. The nation -- West Africa’s biggest oil producer -- is due to export around 1.68 million barrels of crude a day in May, the largest rate in three months, according to data compiled by Bloomberg.
