Comet Ridge Limited and Vintage Energy Limited jointly announced that their Galilee Basin joint venture in central Queensland, has been awarded six Potential Commercial Areas (PCAs) by the Queensland Department of Resources (DoR). Two Authorities to Prospect (ATPs 743 and 744) were initially awarded to Comet Ridge Limited in 2009. Exploration was initially coal seam gas (CSG) focussed with Comet Ridge undertaking a significant 2D seismic survey, the drilling of nine CSG exploration and appraisal wells and a short term production test on the Gunn 2 well.

In 2018, Vintage Energy farmed into the "Deeps" section of the blocks by funding the Albany 1 well and additional 2D seismic, which was aimed at the deeper sandstone reservoir sections of the Permian aged Galilee Basin Sandstone. In exchange for this expenditure, Vintage Energy acquired a 30% interest in the "Deeps" whilst Comet Ridge retained 70%, along with its 100% interests in the CSG Shallows. The Albany 1 well flowed 230,000 cubic feet of gas per day and confirmed that these deeper sandstones could indeed be productive.

The joint venture participants have identified up to 20 leads and prospects in this deeper section of the basin for future appraisal. As part of the normal exploration process for natural gas in Queensland, towards the end of the ATP tenure term, Comet Ridge and Vintage Energy carried out a technical review to determine the parts of ATP 743 and 744 that are considered to be the most commercially prospective. The joint venture participants identified six separate areas, totaling approximately 4700 km2, for tenure to be secured under Potential Commercial Area (PCA) applications.

These areas, numbered by the Queensland Government as PCA 319 to 324 have been awarded to Comet Ridge and Vintage for a term of 15 years to enable further appraisal to be undertaken. The underlying permits, ATP 743 and 744 have also been renewed for a further term of 12 years.
