The Yemeni government announced, on Saturday, two modifications to two governorates' crude oil to raise Masila crude oil price to $77.49 for barrel and Marib's to $79.24.
Minister of Oil and Minerals Khalid Bahah said that increasing prices is the highest since Yemen started exporting crude oil .

This increase is due to stopping oil production in Nigeria and the low supply of OPEC which engender fears of shortage of international oil supply.
