Suttles Completions Underway

• Completion operations underway on Sabres and Whalers wells
• Both wells drilled and cased, targeting Sycamore and Woodford formations
• Company holds approximately 70% working interest in the Suttles development

Brookside Energy Limited (ASX: BRK) has announced that completion operations are underway on the Sabres 2-1-1S-3W SXH1 and Whalers 2-1-1S-3W WXH2 wells at the Suttles Pad in the Company's SWISH Area of Interest in Oklahoma's Anadarko Basin. The commencement of completion operations follows the successful drilling and casing of both wells and marks the final major phase of the Suttles development before the wells are brought into production. The frac spread and associated equipment have been mobilised to location, with water handling and surface systems commissioned and high-pressure frac lines successfully tested. The team has now moved into stimulation operations, with a total of 64 stages planned across the two wells. Sabres targets the Sycamore Formation and Whalers the Woodford Formation. The two wells will be completed using a continuous zipper-frac program, moving from well to well as the team works through the planned stimulation stages across both laterals. Following the stimulation program, the wells will progress through drill-out and clean-up operations before commencing flowback. Production facilities are being readied in parallel ahead of first sales. Brookside holds an approximately 70% working interest in the Suttles development.
