Calima Energy Limited, an Australia-based oil and gas exploration and production company founded in 2005 and headquartered at 28 Station Street, Unit 103, West Leederville, Western Australia, focuses on assets in the Western Canadian Sedimentary Basin; it develops and operates conventional oil and natural gas plays targeting formations such as Sunburst, Glauconitic, and Sparky, with core operations historically encompassing the Brooks and Thorsby areas in Alberta comprising approximately 69,000 and 62,800 acres respectively, alongside production from over 75 wells at Brooks yielding about 2,600 boe/d and 14 wells at Thorsby producing over 1,100 boe/d, while retaining a 100% interest in the Paradise Field well in British Columbia that generates around A$350,000 in annual free cash flow. The company serves energy markets in North America through its Canadian projects, emphasizing environmentally responsible production. In January 2024, Calima agreed to sell its wholly owned Canadian subsidiary Blackspur Oil Corp., which held the Brooks and Thorsby assets, to Astara Energy Corp. for CAD 75 million (A$83.3 million) subject to shareholder and regulatory approvals expected by March 2024, enabling distribution of over 85% of proceeds to shareholders and retention of the Paradise asset for future exploration and operations.
