Brookside Energy Advances Sabres Well Into Lateral Section at Suttles Pad
Brookside Energy has advanced its Sabres 2-1-1S-3W SXH1 well into the lateral section after successfully setting intermediate casing and landing the curve in the Sycamore Formation at the Suttles pad in Oklahoma’s Anadarko Basin. The well, part of a two-well development programme announced 7 July 2026, has reached a measured depth of approximately 9,800 feet as drilling continues through the approximately 1.5-mile lateral. Brookside holds an approximate 70% working interest in both Suttles pad wells.
The drilling milestones achieved so far
The Sabres well has progressed through several critical construction phases, systematically retiring key wellbore risks:
- Drilled to the planned intermediate casing point
- 9⅝-inch intermediate casing run and cemented to designed depth
- Successful pressure test confirmed installation integrity
- Drilling resumed through the casing shoe into the curve section
- Curve landed at the planned point in the Sycamore Formation
- Now drilling ahead through the ~1.5-mile lateral (~9,800 ft measured depth)
The intermediate casing secures and isolates the upper wellbore, with the successful pressure test confirming the integrity of the installation. Drilling then resumed through the casing shoe and into the curve section, subsequently landing the curve at the planned point to place the well on its planned trajectory through the target formation.
David Prentice, Managing Director & CEO
“We have set and tested the intermediate casing, successfully landed the curve and are now drilling ahead in the lateral as planned. These milestones have now retired several key well-construction and drilling risks. From here, the team is focused on reaching the planned target depth, running and cementing the production casing string and then moving directly to Whalers.”

Understanding the drilling process: why these milestones matter
A horizontal well involves three major sections: a vertical wellbore drilled down to depth, a curved section that transitions the wellbore towards horizontal, and a lateral section that extends through the target formation. Setting intermediate casing and landing the curve are critical checkpoints because they lock in wellbore integrity and confirm the well is positioned correctly in the formation before drilling the productive lateral.
For investors, “retiring drilling risk” means each successfully completed stage reduces the chance of costly delays or wellbore problems, keeping the programme on budget and schedule. The Sabres well is progressing as planned, de-risking the development as it advances towards production casing installation.
What comes next: production casing and the Whalers well
Following completion of the Sabres lateral, production casing will be run and cemented before the rig skids across the Suttles pad to drill the Whalers well, targeting the Woodford Formation. Sabres is the first well in the two-well Suttles pad development programme.
| Well | Pad | Target Formation | BRK Working Interest | Status |
|---|---|---|---|---|
| Sabres | Suttles | Sycamore | ~70% | Drilling lateral (~9,800 ft MD) |
| Whalers | Suttles | Woodford | ~70% | Next to drill |
