Primeline spuds LS23-1-1 well

Primeline Energy Holdings Inc. (Primeline) has announced the drilling of its LS23-1-1 exploration well has commenced to tap into resources near its LS36-1 gas field production facility.

Primeline’s drilling contractor, China Oilfield Services Ltd, started to tow the drilling rig, HYSY941, on 15 September. The rig arrived at LS23-1-1 on 17 September and the subsequent jackup and loading operation was successfully completed. LS23-1-1 was spudded on 23 September 2015.

The LS23-1-1 well is in 81 m of water in Block 33/07 in the East China Sea and is 24 km from the LS36-1 gas field platform. The planned total depth of the well is designed to be 2688 m with several target zones in Palaeocene sediments.

LS23-1-1 is the first exploration well (of two) in Primeline’s current campaign as part of the rolling development program. Based on the result of this well, Primeline will finalise the drilling location of the second well in Block 33/07, which will be either LS30-3-1 or LS23-2-1. Any resources discovered in this drilling campaign can use or share the LS36-1 gas field production infrastructure to speed up development and optimise future development costs and economics.

The drilling is scheduled to take approximately 30 days including logging. If hydrocarbons are discovered, additional logging or drill stem tests will be carried out.
