LF 7-3-1 completed in early July 2020 without result reported.   CNOOC â Shenzhen spudded a new-field wildcat in the Pearl River Mouth Basin, South China Sea, on 17 June 2020. Lufeng 7-3-1 (LF7-3-1) is located in the Lufeng Sag, in the north of LF 7-2, in a water depth of 120 m area. The well is believed to be targeting the Mio â Oligocene clastic play. âNanhai 5â S/S is used for the drilling operation.   The Lufeng Sag is one of the important exploration focuses for CNOOC in the Pearl River Mouth Basin. For the past few years extensive drilling progress has been carried out.  In early 2020, CNOOC drilled LF 7-8-1 and LF 9-8-1, both wells completed without result reported.   In June 2019, CNOOC made two discoveries in the Lufeng Sag, LF 9-4-1 and LF 7-10-1d completed as an oil discovery well.   In 2018, SK Innovation made LF 12-3-1 discovery. The well was drilled to a TD of 2,014 m and encountered 34.8 m net oil pay. Test rates from the well was up to 3,750 bo/d from the Lower Miocene Zhujiang Formation.  In 2017 CNOOC made discovery in LF 14-8-1 and tested oil from the Oligocene Enping Formation.   In 2016, LF 7-9-1 was drilled and completed as a dry hole.   In 2014, CNOOC made discovery of LF 8-1-1 and LF 14-4-1. LF 14-4-1 penetrated about 150 m of oil pay and tested 1,320 b/d of oil from the Lower Tertiary Zhuhai Formation  Background Information  There are several fields on production in the Lufeng Sag:   LF 7-2 field is operated by Newfield and it was on stream in 2014. The field is producing from the Zhujiang reservoir at a rate of 10,300 bo/d in 2018.   LF 13-2 field, operated by CNOOC, also has reservoir in the Zhujiang Formation and on stream in 2006. It is produced at a rate of 3,500 bo/d in 2018.   LF 13-1 field has primary reservoir in the Zhujiang Formation and secondary one in the Oligocene Enping Formation. The field has been producing since 1993 and produced at a rate of 5,200 bo/d in 2018.   LF 22-1 field - The field was officially shut down in June 2009 after nearly 12 years production as the field depletion.  In 2019, CNOOC is preparing to launch a new overall development plan for Lufeng oil fields cluster in the South China Sea oil fields cluster.  The Lufeng oil fields cluster, including Lufeng 14-4/14-8/8-1, Lufeng 15-1 and Lufeng 22-1, lies in the east or southeast part of the existing Lufeng oil fields group Lufeng 7-2 and Lufeng 13-1 fields. The Lufeng 22-1 field SPS will be connected to the drilling/production platform in the Lufeng 15-1 field via a 19 km of pipeline. A drilling/production platform will be built in the Lufeng 14-4 field and linked with the platform in the Lufeng 15-1 field via a 23.8 km pipeline.
China (Pearl River Mouth B.), Lufeng 7-3-1 (LF7-3-1) operated by CNOOC LTD (100%) in Huizhou 05 block, WD = 120 m, without result reported.
