Rosneft begins exploration drilling in Block 06.1 offshore Vietnam
Rosneft's subsidiary Rosneft Vietnam has commenced drilling at exploration well PLDD-1X located in at Block 06.1 of the Nam Con Son Basin, about 365km offshore of the southern coast of Vietnam.
The start of the drilling marks Rosneft's first individual international offshore drilling project as an operator.
With a design depth of around 1,380m and a sea depth of around 162m, the well is planned to be drilled using Japan Drilling-owned HAKURYU-5 drilling rig.
The well is estimated to have recoverable natural gas reserves of 12.6 billion cubic meters, with 0.6mt of gas condensate in the PLDD geological structure, the firm said.
Upon completion of the PLDD-1X well drilling, Rosneft plans to drill another exploration well located in Block 05.3/11, also in the Nam Con Son basin.
Owned completely by Rosneft Vietnam, the block 05-3/11 has an estimated hydrocarbon potential of 40 billion cubic meters of gas and 9 million tons of gas condensate.
The company said that by incorporating the two wells into the same program would reduce timelines for implementation of the works.
Rosneft management board chairman Igor Sechin said: "I am sure that the experience gained in Vietnam will be used by the company not only in its activity in the southern seas; these competences will find application in planning and implementation of upstream projects in remote areas.
"I would especially like to emphasise that this project is an example of advanced cooperation with the company's partners in the Asia-Pacific: Petrovietnam and ONGC."
Rosneft operates the block 06.1 as part of a production sharing contract (PSC) with 35% stake. The PSC area comprises two gas condensate fields including Lan Do and Lan Tay.
In an effort to boost production recovery and explore potential in deeper prospects, the firm plans to undertake broadband 3D seismic at Block 6.1 later this year.
Rosneft also has oil and gas assets in Venezuela and Canada as well as exploration prospects in several other countries.
