Abdul Hussain Bin Ali Mirza, chairman of Bahrain's National Oil and Gas Authority (NOGA), has said that in the coming 20 years Bahrain will spend about $13 billion in the oil and gas industry. NOGA expects that of this amount up to $8 billion will be spend on oil and gas exploration, development and production. The remaining amount of $5 billion will be invested on the upgrading and modernization of the Bahrain refinery, including the construction of a new unit at a cost of $1 billion. There is also a plan to increase kerosene and diesel output by eleven per cent and to modernize existing units, which if everything goes according to plans will be reduced from five to two or three. NOGA also plans to build a new pipeline to convey Saudi Arabian crude oil to be refined in the country's refinery. Crude oil imported from Saudi Arabia through the oleo ducts also increased by 6.1 percent, Oil Minister and NOGA Chairman Dr Abdulhussain Mirza said. Crude oil pumped to Bahrain Refinery increased 4 percent to top 49.407 million barrels. Exports of oil byproducts include naphtha, petrol, kerosene, air fuel, diesel, fuel oil, limestone and asphalt.
