Australian independent Beach Energy is commencing a significant 12-well appraisal and development drilling campaign on the Western Flank of the prolific Cooper basin, targeting gas and oil prospects.

Campaign Objectives and Targets

The primary objective of this campaign is to target undeveloped oil reserves within the McKinlay and Birkhead reservoirs, with the specific aim of arresting the production decline observed in recent years. The program is expected to include wells across the Bauer, Callawonga, Kalladeina, and Snatcher fields.

Operational Strategy and Efficiency

Beach Energy has emphasized a key focus on operational efficiencies and cost savings for this campaign. The planned strategies to achieve this include:

• Utilizing dual laterals to reduce the number of wellheads, connections, and pumps.
• Drilling from common drill pads.
• Employing slimbore drilling techniques to reduce the amount of casing and cementing required.

Future Exploration and Geological Context

An oil exploration campaign is being developed and is expected to follow the 12-well appraisal and development program. The Cooper basin itself is a Permian to Triassic-aged geological sequence deposited in a terrestrial fluvial-lacustrine environment. The major source rock units are the Permian-aged coals and carbonaceous shales found in the Patchawarra and Toolachee formations.

Recent Drilling Context and Future Plans

This new campaign follows the recently completed Hercules wildcat in the Otway basin offshore Victoria, which was a moderate to high-risk target that failed to intersect hydrocarbons. Looking ahead, the second phase of the Equinox rig's drilling campaign is scheduled to commence in the first quarter of 2026. This phase includes:

1. Drilling and completing the La Bella 2 development well.
2. Completing the Artisan discovery.
3. Performing a well intervention at Thylacine.
4. Abandoning the Trefoil-1 and Yolla-1 wells in the Bass basin.

Company's Market Position and Other Developments

Beach Energy currently supplies 19% of Australia's East Coast gas demand, following approximately A$2 billion (US$1.3 billion) of investments over the past five years. In a separate but significant development, the company announced that its much-delayed Waitsia gas plant has achieved the ready for start-up milestone. The delivery of sales gas into the Dampier-to-Bunbury natural gas pipeline in Western Australia is expected imminently. The Waitsia plant has a gross nameplate capacity of 250 terajoules per day, representing about 20% of Western Australia's current domestic gas demand. Initially, volumes from this plant will be directed to the Woodside Energy-operated North West Shelf project for processing and sale as liquefied natural gas to international customers, with the plant eventually supplying gas directly to the Western Australian domestic market.
