Brookside Energy (ASX:BRK) positions for growth as new sub plays emerge in the SWISH AOI

Brookside Energy (ASX:BRK) is sharpening its strategic edge in the Anadarko Basin with the identification of new productive intervals in the SWISH Area of Interest (AOI).

These new sub plays, including the Simpson Group sands and the Caney Shale, could represent a fresh wave of development opportunity for the company.

Market Open sat down with Brookside Energy Managing Director David Prentice to explore what this means for the company’s development strategy, how infrastructure is supporting growth, and what investors should watch as the basin’s momentum builds.

What is the significance of identifying new sub plays in the SWISH AOI?

This development is highly significant for us because the SWISH Area of Interest, already regarded as one of the most attractive parts of the Anadarko Basin due to its stacked pay potential, is now revealing two additional productive intervals: the Simpson Group sands and the Caney Shale.

These zones have not been developed to the same extent as the more mature targets in the basin, but modern horizontal drilling and completion techniques are beginning to unlock their potential.

Early scout well results and increased leasing activity across the region are very encouraging.

“For Brookside, holding a strategic land position in an area that continues to generate new sources of value means these emerging sub plays could add fresh development inventory and allow us to boost future production without the need to materially expand our footprint.”

How does this update fit into Brookside’s broader development strategy?

The update aligns perfectly with the strategy we have pursued over the past several years, which is to create value through disciplined development rather than high risk exploration.

By focusing on areas where multiple hydrocarbon bearing formations can be accessed from a single drill site, we enhance capital efficiency and long term returns. The identification of these sub plays strengthens that approach.

“If the intervals prove commercially viable, they could allow us to accelerate new development phases, extend the life of our acreage, and maximise returns from existing infrastructure and past investment.”

We are not simply chasing new targets. We are assessing which ones align with our technical and economic criteria, and these sub plays are showing real promise.

Who else is active in these sub plays, and what does their success mean for Brookside?

One of the most encouraging aspects is the calibre of operators involved.

Continental Resources, the largest and most successful independent exploration and production company in Oklahoma, is leading the charge in these zones, which strongly endorses both the geology and the underlying economics.

Kolibri Energy has also demonstrated consistent success in the Caney Shale approximately 60 miles southeast in the Tishomingo Field, their work further supports the commercial potential of the Caney when developed with the right approach.

This is not a theoretical opportunity, it is happening on the ground, and Brookside is well positioned to benefit from that activity.

How does infrastructure in the Anadarko and Ardmore Basins support development of these new plays?

Existing infrastructure is a major advantage because the basin is already serviced by pipelines, gas processing plants, and refineries.

This eliminates long delays in connecting to market and translates into lower upfront costs, faster development timelines, and improved netbacks.

For Brookside, the ability to access this infrastructure provides a level of flexibility and cost control that is not always available in other basins, it also enhances our pricing power by offering multiple market access points.

This infrastructure backbone continues to attract investment and reinforces our confidence in the long term value of our position.

What are the next steps for Brookside in terms of these sub plays?

Our current focus is on monitoring activity and results across the basin, particularly where operators are targeting the Simpson Group sands and the Caney Shale.

We are conducting technical due diligence, reviewing data from scout wells, and closely tracking leasing and permitting trends.

“Because we already hold a strategic position within the SWISH AOI, we can afford to evaluate the commercial potential as it unfolds and then act decisively at the appropriate time.”

If early production data aligns with our geological interpretations, we will determine how best to incorporate these zones into our broader development program.

This could include new well planning, revised spacing strategies, or selective partnerships that support shareholder value.

Looking ahead.

Brookside Energy’s methodical and technically driven approach continues to deliver upside in the Anadarko Basin.

With strategic land holdings, access to world class infrastructure, and validation from leading operators in the region, the company is positioned to move swiftly and efficiently as new opportunities emerge.

The evolving sub play potential in the SWISH AOI could represent the beginning of Brookside’s next growth phase, underpinned by commercial discipline and long term value creation.
