Offshore staff

LONDON  ̶  Primeline Energy Holdings says China National Offshore Oil Corp. has agreed to extend the exploration period for Primeline’s petroleum contract for block 33/07 in the East China Sea.

Phase one now runs until April 30, 2016, with the two remaining phases kept at two years each.

Minimum work program for the first period is 600 sq km (231 sq mi) of 3D seismic acquisition and drilling of two exploration wells.

Primeline fulfilled the seismic commitment last year and is currently drilling exploration well LS23-1-1, which should reach TD of 2,688 m (8,819 ft) by the end of this month.

China Oilfield Services Ltd. has completed drilling of the 17½-in. hole to 1,326 m RT and set the 13⅜-in. casing, and planned to start drilling the 12¼-in. section on Oct. 13.

The well is targeting several reservoir zones in this section. Based on the results, Primeline will finalize the drilling location of the second well in the block, which will be either LS30-3-1 or LS23-2-1.

Any resources discovered during this campaign could be developed through the LS36-1 gas field production infrastructure.

For the other two phases, the minimum work program is one exploration well.
