Primeline Energy Holdings Inc. has announced that its drilling contractor China Oilfield Service Ltd. (COSL) has started the mobilization of the rig for the drilling operation of LS23-1-1 well in the East China Sea.
Following the signing of the drilling contract by Primeline with COSL on August 17, 2015, COSL has completed the site survey of the well locations and other preparations for the drilling operations, including the applications for the required operation permits, Primeline said in a press release issued Wednesday.
“Primeline held a pre-spud meeting with COSL and all main subcontractors on September 14. COSL started to tow drilling rig HYSY941 toward the well LS23-1-1 location on the evening of September 15,” the company added.
According to Primeline, the towing operation is expected to last three to five days, subject to weather and sea conditions, followed by jack up, with drilling operations expected to start around September 22.
The COSL HYSY941 is a self-elevating jack up rig built in 2006 by Dalian Shipbuilding. The rig has a maximum drilling depth capacity of 9,150 m and is capable of operating in up to 122 m water depth. The rig can accommodate 145 personnel and has full international certifications.
