RIO DE JANEIRO, May 14 (Reuters) - Brazil's OGX and Britain's BG Plc won offshore oil and gas explorationblocks in a frontier region of Brazil's Barreirinhas offshorebasin at an auction on Tuesday conducted by oil regulator ANP.
The companies won the rights to blocks off the Brazilianstate of Maranhão. The area is part of a swath of the country'sfar northern coast known as the "Equatorial Margin."
Brazil's ANP believes the Equatorial Margin blocks on offermay contain about 30 billion barrels of oil in place. Whileactual production would probably be far less, that's enough oilfor nearly 11 months of global oil demand.
