Woodside Energy Ltd spudded the Ferrand 1 exploration well in WA-404-P, located in the North Carnarvon Basin, on 17 April 2018.Â  On 18 June 2018 the well was plugged and abandoned, after reaching a total depth of 5,035 m.Â  In mid-July 2018, Woodside reported that the well had made a gas discovery, encountering a 69 m gross gas column.Â  Assessment of the wells results is ongoing.   Woodside reported that the Ferrand well was targeting a âlargeâ volume of gas, within an anticlinal trap, which is considered to be over 100 MMboe. The well targeted a structural trap within Triassic units.Â  Within the region, successful targets have lain within the Upper Jurassic sands of the Jansz and Triassic Mungaroo formations. Ferrand is estimated to cost around AUD 50 million to drill. Â The well was drilled by the âEnsco MS1â S/S and had a planned total depth of 5,200 m.  The commitment to drill in WA-404-P lies in Term Five and as such the commitment to drill was required by the start of the term in February 2017. There have been no permit suspensions or changes to the original work programme since Woodside renewed the permit on 17 July 2013. Woodside has already submitted an Environmental Plan to the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).    WA-404-P, which covers an area of 1,377 sq km, was awarded on 17 July 2007 and is 100% owned and operated by Woodside Energy Ltd.
