SEE How Drastically Nigeria’s Oil Revenues Declined
  The Nigerian National Petroleum Corporation’s report  shows why Nigeria’s economy experiences difficulties – and if the trend  continues the situation may get even worse.        Nigeria’s oil revenues sharply declined within a year by over two thirds, says the report, recently published by the NNPC.   The NNPC report shows that oil revenues declined more than 67 per  cent over a period of time since September 2014 till July 2015, and that  had “ dire consequences to the federation “. However, if that  rends continues, the situation in Nigeria’s economy, heavily dependent  on oil revenues, may get even worse. Nigeria derives more than 90 per  cent of its foreign exchange earnings from crude.
