On 30 April 2020 Carnarvon Petroleum Ltd increased its interest holding in exploration permit WA-155-P, located in the North Carnarvon Basin, to 70% and took operatorship of the permit. Joint venture partner Skye Exploration Pty Ltd decreased its holding, from 71.5% to 30%.  Carnarvon reported that it is aiming to mature the prospect to enable future farm-out of interest.  A number of prospects, primarily within the Triassic Mungaroo, have been identified within the permit. The primary prospect, the Belgravia Prospect, has been outlined. Carnarvon reported, in May 2020, that the prospect could be part of a much larger structure, that it has identified as the Jurabi-Belgravia-Swell (JBS) structure, part of which lies in WA-155-P. Both the Swell and Jurabi wells, drilled in 2017 and 1982 respectively, exhibited low porosity, though Carnarvon reports the larger JBS structure could have a better average porosity. The top Triassic at Belgravia is thought to be around 4,500 m. If a significant commercial gas discovery was made there would be the option for a standalone development, or tie-back to the existing northwest shelf LNG projects.  The permit already contains the Outtrim oil discovery, which was made in 1984.  WA-155-P, which covers an area of 289 sq km was awarded on 1 March 1981. With the interest change complete, participants in the permit are Carnarvon Petroleum Ltd (70% + Operator) and Skye Exploration Pty Ltd (30%).
Carnarvon (Skye Explo->30%).  has taken over operatorship of WA-155-P while increasing its interest to 70% ('Outtrim project').
