Lufeng 28-4-1 (LF 28-4-1) was plugged and abandoned (results TBC) in mid-February 2018 after having been spudded in late January 2018 using the "Nanhai 6" semi-sub. The oil exploration well was likely targeting the Zhuhai and Enping formations. SK Innovation was carrying out a two well exploration drilling programme in Block 17/03 PSC, making an oil discovery with the first exploration well Lufeng 12-3-1 which flowed 3,750 bo/d upon testing. Lufeng 28-4-1 is in Block 17/03 PSC in the offshore Pearl River Mouth Basin. Rightholders of Block 17/03 are SK Innovation (80%, operator) and CNOOC (20%), with CNOOC having the rights to back-in for a further 51% interest in the development and production phase.
