Australia: Offshore Wildcat Spuds
BP’s much-anticipated Ironbark-1 offshore wildcat was finally spudded at the end of October 2020 offshore the North West Shelf of Australia. The well, in the Carnarvon Basin, Western Australia, is immediately north-east of the great Greater Gorgon LNG development fields, operated by Chevron and Shell. It is expected to take 70–90 days to drill and has a best estimate of 15 Tcf of prospective recoverable gas. Ironbark-1 has a TD of 5,500m and is targeting the Middle Triassic Mungaroo Formation, which is a fluvio-deltaic succession of sandstones and claystones. This formation is a common reservoir for other discoveries in the area.
