Canada's Talisman Energy Inc. said on Monday it had won the right to explore oil and gas in block 15-2/01 in the Cuu Long Basin, off Vietnam's southern coast.
Details of oil and gas reserves in the block were not immediately available.
Block 15-2/01 is adjacent to Vietnam's second biggest producing oil field, the Su Tu Den (Black Lion), which churns out around 85,000 barrels per day (bpd).
Talisman is the operator of oil fields in the PM-3 CAA block and Block 46-Cai Nuoc that produce Vietnam's Bunga Kekwa crude, with output averaging 60,000 bpd.
