Horizon Oil has advised that the WZ 6-12 M1 exploration well, Beibu Gulf, People’s Republic of China, spudded at 00:30am local time on 25 October 2019. The well is located in between the Weizhou 6-12 North and South Fields and is targeting the T40 - T42 stacked reservoirs.

The well objective is to evaluate the structure, sand and oil column thickness in the undeveloped WZ 6-12 Mid Prospect, which is located on the footwall side of a major east-west trending normal fault that separates it from the WZ 6-12 South field. In the event of a discovery, the intention is to integrate its development with the adjacent WZ 6-12 North and South fields.

The current operation is drilling the 12 ½ in. hole at 681 m MD, towards section TD at 1440 m MD. The well is anticipated to take about 17 days from spud to drill to a planned total depth of 2025 m MD.
