The Woodside-BG alliance was awarded the A4 and A7 (both Woodside 45%, BG 45%, Myanmar Petroleum Exploration and Production 10%) shallow water blocks and the AD2 (BG 55%, Woodside 45%) and AD 5 (Woodside 55%, BG 45%) deepwater blocks.
Queensland Curtis LNG project operator BG said the blocks were in the Rakhine Basin of western offshore Myanmar.
"BG Group and its bidding partners have committed to a 3D seismic acquisition program in each block, which we expect to begin in 2014/15 with options for future drilling," it said.
"This award is in line with BG Group's strategy to focus on securing prospective frontier acreage and enter, on average, one new basin each year."
The Burmese sovereign state offered 30 blocks in November last year, 11 in shallow water and 19 in deep water in its maiden offshore licensing round with the likes of Shell, Eni, Chevron, Statoil and ConocoPhillips also making successful bids.
The latter two won a deepwater exploration block in the Bay of Bengal, where they will undertake a joint venture, representing a new country entry for Statoil.
"This is a large and virtually unexplored area in a basin with a proven petroleum system and thick sedimentary deposits," Statoil eastern hemisphere senior vice president Erling Vagnes said.
"With this award, we have accessed at scale in another frontier acreage with significant upside, in line with our exploration strategy."
Smaller players such as Hawkley Oil and Gas were unsuccessful in their bids, with the junior trying to expand its efforts outside of the Ukraine.
Hawkley applied for three shallow water licences in partnership with Azimuth Resources but was advised it had been outbid by the majors.
"While HOG submitted a highly competitive bid, the blocks were hotly contested, evidenced by the fact the vast majority of the licences were awarded to global major energy companies," Hawkley managing director Richard Reavley said.
"This highlighted the fact that we are assessing viable acquisition opportunities in the right neighbourhood."
Other smaller companies got lucky, with Australian explorers Tap Oil and Roc Oil taking the M-7 shallow water lease.
"Myanmar contains a number of established and producing hydrocarbon basins and is a potentially world-class petroleum province, which will benefit significantly from the introduction of recent advances in exploration and development technologies," Roc Oil CEO Alan Linn said.
Chevron made a winning bid for the A5 shallow water block in partnership with Unocal Myanmar Offshore Company.
Eni Myanmar won the MD-2 and MD-4 deepwater blocks.
