The Lam Son Joint Operating Company (Lam Son JOC) has found commercial oil while drilling two wells at the Thang Long field Lot 02/97 about 160 km to the east off shore the southern Ba Ria-Vung Tau province.
The new oil field is located in Cuu Long sediment basin, 27km southeast of the Ruby oil field and 80km northeast of the Bach Ho (White Tiger) oil field.
As the Thang Long field has oil-bearing bed lying in a record shallow level in the Cuu Long sediment, it is considered to be a convenient place for oil exploitation.
According to General Director Nguyen Quyet Thang of Lam Son JOC , a joint venture between PetroVietnam and Petronas Carigali Overseas Sdn. Bhd of Malaysia, his company has discovered oil in all three wells it has drilled so far. They are Thang Long-1X, Thang Long-2X, and Thang Long-3X wells.
