Primeline Energy Holdings Inc. Wednesday announced the drilling of its LS23-1-1 exploration well, in the East China Sea, has started, tapping into resources near its LS36-1 gas field production facility.
As Primeline recently reported, its drilling contractor China Oilfield Services Ltd started to tow the drilling rig, HYSY941, on September 15. The rig arrived at LS23-1-1 on September 17 and the subsequent jack-up and loading operation was completed. LS23-1-1 was spudded on September 23, 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 2,688 m with several target zones in Palaeocene sediments.
Primeline says that 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.
LS23-1-1 is the first of two exploration wells in Primeline’s current campaign as part of the rolling development program. Based on the result of this well, Primeline will finalize the drilling location of the second well in Block 33/07, which will be either LS30-3-1 or LS23-2-1.
Primeline emphasized that any resources discovered in this drilling campaign could use or share the LS36-1 gas field production infrastructure to speed up development and optimize future development costs and economics.
