This operation is part of the step-out drilling campaign that Primeline is implementing as part of its rolling exploration and development strategy. Primeline and CNOOC are preparing for the development of Lishui 36-1 gas field following signing of development agreements with CNOOC in March.

The Lishui 35-3-1 well is one of the main prospects in the exciting new play concept in the vicinity of the Lishui 36-1 gas field. Any resources that may be discovered in these prospects will benefit from the infrastructure to be built as part of the development program, the company said.

Primeline is an exploration and development company focusing exclusively on China resources. It has a 75% contractor’s interest in the petroleum contract with CNOOC for block 25/34, an offshore exploration area of 5,221sqkm in the East China Sea, where the Lishui 36-1 discovery is located.
