Rosneft spuds Vietnam well

Offshore spud: the semi-submersible Hakuryu-5

Russian operator Rosneft has spudded the first of back-to-back exploration wells in Vietnam’s Nam Con Son basun within close proximity of its Lan Tay production platform.

The PLDD-1X well is located in 162 metres of water in Block 6-1, which contains the producing Lan Tay and Lan Do gas fields.

Rosneft said the pre-drill potential of the PLDD structure is 12.6 billion cubic metres of gas and 5.4 million barrels of condensate that can be developed by subsea completion and tie-back to the Lan Tay platform.

The Russian company has hired Japan Drilling's semi-submersible Hakuryu-5 for the two wells.

The second well will be in adjoining Block 5-3/11, which is owned 100% by Rosneft.

Rosneft said it also plans to shoot 3D broadband seismic in Block 6-1 later this year “to enhance ongoing production recovery and explore potential in deeper prospects”.
