Brookside Energy (ASX:BRK) banks on Gapstow success as SWISH play delivers production punch

When it comes to drilling for value, Brookside Energy (ASX:BRK) is proving there’s more than one way to tap into opportunity.

The Perth-based energy junior has revealed robust early production results from its non-operated Gapstow Wells in Oklahoma’s prolific Anadarko Basin, with the wells turning out 1.65 million barrels of oil equivalent (BOE) in their first three months—nearly three-quarters of which was liquids.

For Brookside Energy, this equates to approximately 27,500 BOE net.

Operated by US heavyweight Continental Resources, the Gapstow Wells are part of a full-field development program targeting the Sycamore Lime and Woodford Shale formations in tandem—an approach designed to maximise hydrocarbon recovery while improving operational efficiency.

With a net revenue interest of around 16% across eight of the Gapstow wells, Brookside isn’t just a bystander.

The company is reaping the rewards of its exposure to the SWISH Play, a sweet spot within the broader Anadarko Basin that’s earning a reputation for high recoveries per drilling spacing unit (DSU).

Brookside Managing Director David Prentice noted,

“We are very pleased with the outstanding performance of the Gapstow Wells and proud to be partnering with Continental on this exciting project. These results continue to validate our strategic focus on the SWISH Play and the value of participating in high-quality, non-operated projects.”

The numbers back up the optimism: an average initial production over 90 days (IP90) of 1,792 BOE per well (normalised to a 10,000-foot lateral), with 73% of that figure coming from liquids.

This IP90 metric is widely regarded in the industry as a key indicator of longer-term well productivity.

While Brookside continues to grow its operated well portfolio through subsidiary Black Mesa Energy, this non-operated position complements its cash flow and strengthens its working capital base.

It’s a textbook case of the company’s “exploitation over exploration” mantra—leveraging partnerships and disciplined investment to generate value without shouldering the full burden of operational execution.

With more updates to come across its Anadarko Basin portfolio, Brookside’s recent run serves as a timely reminder: sometimes the smartest play is knowing who to work with—and when.
