Brookside Energy (ASX:BRK) is an Australian-listed oil and gas company focused on developing production Assets in Oklahoma’s Anadarko Basin. The company is advancing a two-well drilling program at its Suttles pad, with activities designed to increase production from its US-based acreage position.

At the time of writing on 14 August 2026, Brookside Energy (ASX:BRK) was trading at AUD 0.38, unchanged on the day.

The company’s near-term focus remains completing the Whalers well, conducting fracture stimulation activities and progressing both wells toward production.

What Just Happened?

On 5 August 2026, Brookside confirmed completion of drilling and casing activities at the Sabres well, formally known as Sabres 2-1-1S-3W SXH1, located on the Suttles pad within the SWISH Area of Interest.

The well reached a total measured depth of approximately 4,328 metres and targeted the Sycamore Formation. Production casing was installed to the bottom of the well, cemented and pressure tested.

Following completion of Sabres, Brookside commenced drilling the second well, Whalers 2-1-1S-3W WXH2, targeting the deeper Woodford Formation.

Both wells are being drilled by Kenai Drilling’s Rig 18, with Brookside holding approximately 70% interest in each well. The company has also progressed surface infrastructure activities, including production facilities and tank battery preparation.

Why It Matters

The two-well drilling program represents an important stage in Brookside’s strategy of growing production through development drilling rather than exploration alone.

Each well includes approximately 1.5-mile horizontal laterals designed to access additional reservoir exposure and support potential production volumes.

Brookside’s ownership interest of approximately 70% in both wells means successful production outcomes could have a direct impact on the company’s production profile.

The company plans to fracture-stimulate both wells after completion of drilling activities, with the approach designed to coordinate operations and move the wells toward first production.

The key measure of success will ultimately be production rates, operating performance and the ability to convert drilling Investment into Revenue generation.

The Bigger Picture

Brookside Energy is focused on oil and gas assets within Oklahoma’s Anadarko Basin, including areas associated with the SCOOP and STACK plays.

The company’s strategy combines existing production with ongoing development drilling, allowing Operating Cash Flow from producing assets to support future activity.

The Anadarko Basin is an established petroleum region with existing infrastructure and a history of oil and gas development. Brookside’s approach is focused on building production through a sequence of development wells rather than relying on exploration discoveries.

The Suttles pad and SWISH acreage represent key parts of the company’s current growth strategy. As a smaller producer, Brookside remains focused on operational execution, production growth and efficient Capital deployment.

What Could Drive the Shares Next?

The next key milestone is completion of the Whalers well, followed by fracture stimulation and production testing of both Sabres and Whalers.

Initial production rates from the wells will provide important information on whether the drilling program achieves targeted outcomes. First sales from the Suttles pad will also be an important operational milestone.

Beyond the current drilling campaign, further development opportunities across Brookside’s Anadarko Basin acreage could support future activity.

Investors will also monitor quarterly production updates, cash receipts and Commodity prices, as oil and gas market conditions influence revenue generation.

Risks Investors Should Watch

Brookside faces risks associated with drilling performance, commodity prices, funding requirements and operational execution. Individual wells may underperform expectations, encounter technical challenges or experience cost increases during completion activities. Oil and gas prices can affect revenue regardless of production performance. As a smaller producer, Brookside may require additional funding to support future development, creating potential dilution risks. Additional considerations include US regulatory requirements, currency movements between Australian and US dollars, and liquidity risks associated with smaller ASX-listed companies.

Bottom Line

Brookside Energy (ASX:BRK) is progressing a two-well development program in Oklahoma’s Anadarko Basin, with the Sabres well completed and the Whalers well underway.

The company is moving closer to the production phase, with fracture stimulation and flow testing expected to provide further insight into the performance of the Suttles pad.

Future value creation will depend on production outcomes, oil and gas prices, funding capacity and continued execution of its US development strategy.
