• Potential development opportunities in Simpson Group sands and Caney Shale formations
• Leasing activity and early drilling results support commercial viability
• Builds on SWISH AOI's 'stacked pay' potential and strategic location

Brookside Energy has announced the identification of two emerging sub-plays within its SWISH Area of Interest (AOI) in the Anadarko Basin, Oklahoma. Recent industry activity has highlighted the potential of targeting previously underdeveloped zones, the Simpson Group sands and the Caney Shale, using modern horizontal drilling and completion techniques. Leasing activity and encouraging early results from scout drilling across the region support the view that these formations can yield commercial production. These developments further enhance the appeal of the SWISH AOI's 'stacked pay' potential, where multiple hydrocarbon-bearing formations can be accessed from a single surface location, improving capital efficiency and long-term recovery. Oklahoma's largest independent E&P company, Continental Resources, is actively advancing these plays, leading a wave of renewed interest in the area. Notably, Kolibri Energy has demonstrated consistent success in the Caney Shale formation nearby, further validating the commerciality and productivity of this reservoir. In addition to the compelling geology, the region offers exceptional access to markets, with extensive existing oil and gas infrastructure. Brookside holds a strategic acreage position in the SWISH AOI and is closely monitoring this activity with a view to potentially expanding its development program into these emerging zones as the plays mature and early commercial success is confirmed.

Brookside is closely monitoring the progress of these new sub-plays within the SWISH AOI and positioning itself to capitalize on these emerging opportunities as they mature and demonstrate commercial viability.
