OVL plans 3D at prize Vietnam block
By the end of this year, OVL and partner Rosneft are hoping to carry out a blanket 3D survey across 955-sq km Vietnamese offshore block 06.1 in the Nam Con Son basin.
They will use the survey results to decide how many additional wells to drill at the producing block which contributes around 12% of Vietnam's gas needs. Right now the consortium is using Japan Drilling Company's semi-submersible Hakuryu-5 to drill exploratory well PLDD-1X which was spud on March 9 in water depths of 162 metres and reached 650 metres by May 21.
This well will be drilled to 1380 metres TD. Block 06.1 is OVL's first overseas asset and has held the exploration license since 1988.
Its PSC area has two gas condensate fields - Lan Tay and Lan Do. Of the 68-bcm in-place gas around 46-bcm was produced by June 2015 after commercial production began in 2002.
Gas is supplied to a 720-MW power station through a 370-km pipeline. Recoverable gas reserves from the PLDD geological structure stand at 12.6-bcm.
