Brookside Energy Completes 64 Frac Stages at Suttles Pad in Oklahoma
Key Takeaways
- Brookside Energy has completed all 64 stimulation stages across the two-well Suttles Pad zipper-frac program, with every stage executed safely and per design.
- Both the Sabres (Sycamore Formation) and Whalers (Woodford Formation) laterals are now secured and transitioning to plug drill-out, production tubing installation, and flowback.
- Brookside holds approximately 70% working interest in both wells, meaning it captures the majority of production revenue once the wells reach sales.
- Surface infrastructure is already well advanced — the sales line is installed and two compressors are in place, reducing timeline risk in the final commissioning phase.
- The next material catalyst for investors is initial production (IP) rates, which will be disclosed once the wells are brought to sales.
Suttles Pad stimulation program wraps up with all 64 stages pumped per design
Brookside Energy (ASX: BRK) has successfully completed the two-well zipper-frac stimulation program at the Suttles Pad, located in the SWISH Area of Interest in Oklahoma’s southern SCOOP. All 64 planned stimulation stages were safely pumped per design across the Sabres 2-11S-3W SXH1 and Whalers 2-1-1S-3W WXH2 laterals, with the frac spread now released from location.
Sabres targets the Sycamore Formation and Whalers targets the Woodford Formation. Brookside holds an approximate 70% working interest in both wells, and operations are now transitioning toward first production.

David Prentice, Managing Director & CEO, Brookside Energy
“This is another good example of the operating discipline we have built across the business. The team has executed a two-well drilling and completion program safely and efficiently, and we are pleased with how the operation has been delivered so far.
“Our job is straightforward: develop our inventory safely, control costs and cycle times, and bring wells online efficiently.”
What a zipper-frac completion means for investors
A zipper-frac is a completion technique where two adjacent horizontal wells are fractured in alternating sequence. Rather than stimulating each well independently, the process alternates between wells in successive stages, maximising efficiency and reducing overall completion time on site.
The phrase “pumped per design” carries real weight for investors. It means all 64 stages were executed safely and according to plan. Clean execution at the completion phase signals disciplined cost control and reduces the risk of delays moving into production.
What comes next follows a defined sequence: plug drill-out (removing the temporary plugs separating each frac stage), production tubing installation, and then flowback, where fluids return to surface before the well stabilises into gas and oil production. Once the wells clear these steps and surface facilities are commissioned, they are brought to sales.
Working interest is straightforward: Brookside bears approximately 70% of costs from these two wells. The completion-per-design outcome de-risks the path to first production. The next material catalyst for investors will be initial production (IP) rates, which will be disclosed once the wells are brought to sales.

Path to production: what comes next at the Suttles Pad
The Suttles Pad is progressing through the final stages before revenue-generating production. Based on the announcement, the near-term operational sequence is:
- Plug drill-out
- Production tubing installation
- Flowback operations
- Final surface facility commissioning (running in parallel)
- Wells brought to sales
The surface infrastructure is already well advanced. The sales line is installed and two compressors are in place, which reduces timeline risk in the final commissioning phase. This is not a project waiting on infrastructure to catch up with the wells.
Geologically, the Suttles Pad offers a degree of diversification within a single operated location. Sabres targets the Sycamore Formation while Whalers targets the Woodford Formation, two distinct pay zones stacked within the same pad. Both formations sit within Brookside’s operated position in Oklahoma’s southern SCOOP, part of the broader Anadarko Basin.
Brookside’s stated strategy is clear: grow production, build scale, and return capital through disciplined development. The Suttles Pad completion milestone moves that strategy forward in a measurable way.
| Well | Formation Target | Stimulation Stages | Status |
|---|---|---|---|
| Sabres 2-11S-3W SXH1 | Sycamore | 64 combined (per-well breakdown not disclosed) | Plug drill-out / flowback pending |
| Whalers 2-1-1S-3W WXH2 | Woodford | 64 combined (per-well breakdown not disclosed) | Plug drill-out / flowback pending |
No production rates or financial outcomes have been disclosed at this stage. The next update of substance will be IP rates once the wells reach sales, and that will be the moment investors can assess the commercial result of this completion program.
