The key players in the country's oil and gas industry are BSP, BLNG, Block B Joint Venture, Brunei Shell Marketing (BSM), Brunei Shell Tankers (BST), and Brunei Gas Carrier (BSC) according to the Petroleum Unit of the Prime Minister's Office in their paper at the Global LNG Summit in Washington DC last December 2003.
The biggest of the four is BSP, which is responsible for the exploration and oil production and natural gas as well as oil refining and crude oil trading.
BLNG, meanwhile, concerns with liquefying the gas it buys from BSP as well as arrangements of its transport and sale to customers in Japan and South Korea.
BST charters tankers to BLNG to transport gas to Japan while, BSM markets petroleum products, such as gasoline, diesel, lubricants, and jet fuel. BSM also MANAGES the import and distribution of lubricants, chemicals and bitumen into the country.
