Brookside Energy Ltd (ASX:BRK) shares gained 1.08% to AUD 0.47 during the afternoon session on 21 May 2026 after the company released a progress update on its upcoming two-well development campaign in Oklahoma’s Anadarko Basin. The stock has also remained approximately 23.68% higher over the past year.

Investor attention appeared to focus on the company’s continued advancement of operational preparations within its SWISH Area of Interest (AOI), where Brookside confirmed that its two-well development pad is now ready to receive the drilling rig.

The latest update outlined several milestones already completed ahead of drilling operations, including conductor installation, pad construction, lease access works, vendor contracting and the commencement of surface production infrastructure.

The announcement represents another step in Brookside’s ongoing development activities across its operated acreage in the SWISH Play, where the company continues to pursue production and reserve growth through a repeatable multi-well development strategy.

Operational Preparations Progress Ahead of Drilling

Brookside stated that preparations for the upcoming drilling program have continued following the commencement of earthworks and access activities announced earlier.

According to the company, the 20-inch conductor has now been set for both the Sabres and Whalers wells, marking another operational milestone before drilling begins.

The company also confirmed that pad construction and lease access works have been completed, allowing the location to be prepared for the arrival of Kenai Drilling Rig 18 once the rig finishes its current commitments.

In addition to the physical site preparation, Brookside advised that key operational vendors have now been contracted for the project. This includes service providers associated with drilling, completions and infrastructure installation.

Construction activities are also underway for the surface production facilities that will support production operations and future first sales from the wells.

The company noted that aligning the drilling schedule, infrastructure work and vendor contracts ahead of mobilisation is intended to support a smoother operational transition from drilling into completion and production phases.

Two-Well Program Targets Sycamore and Woodford Formations

The SWISH AOI development pad will host two separate wells — the Sabres Well and the Whalers Well.

Brookside advised that the Sabres Well is targeting the Sycamore Formation, while the Whalers Well will target the Woodford Formation. Both formations are established hydrocarbon-bearing zones within the Anadarko Basin.

Each well is planned with an approximately 1.5-mile lateral section, designed to maximise reservoir exposure across the targeted formations.

The wells are also being drilled in a similar orientation to nearby development projects operated by Continental Resources, specifically the Courbet and Gapstow development areas located immediately south of Brookside’s acreage position.

The company’s approach reflects its broader development strategy of using repeatable drilling and completion models across its SWISH acreage.

Brookside indicated that the current program forms part of the next stage of its operated development activity in the region and is intended to build on the production base already established within the SWISH AOI.

Program Designed to Support Production and Cash Flow Growth

The company stated that the two-well development program is expected to contribute toward future production growth, reserve expansion and cash flow generation.

Brookside has continued to focus on growing its operated footprint in the Anadarko Basin, one of North America’s more active hydrocarbon-producing regions.

Management noted that the Sabres and Whalers wells are part of the company’s broader strategy aimed at increasing production scale while maintaining a disciplined development approach.

The operational update also highlighted the company’s intention to move efficiently through the various phases of the development process, including drilling, casing, completion, production Facility tie-in and eventual first sales.

Once drilling operations commence, Brookside expects activities to continue without interruption through the drilling and casing stages for both wells on the shared pad.

This multi-well pad approach is intended to support operational efficiencies while allowing the company to continue expanding development activity across its core acreage position.

Infrastructure Work Advances Alongside Drilling Preparations

A notable aspect of the update was the progress being made on associated infrastructure before drilling operations begin.

Brookside confirmed that surface production facilities are currently under construction, including infrastructure required to handle future production volumes and sales operations from the Sabres and Whalers wells.

By progressing infrastructure installation ahead of rig mobilisation, the company appears focused on minimising delays between drilling completion and production startup.

The coordinated timing of drilling, infrastructure development and vendor mobilisation is a common feature of Brookside’s operational model within the SWISH AOI.

The company indicated that this alignment is designed to support operational continuity across all stages of development.

Investors often monitor these early-stage operational updates closely because they can provide insight into project timelines, execution readiness and future production schedules.

SWISH AOI Remains Central to Brookside’s Strategy

Brookside continues to position the SWISH AOI as a core component of its U.S.-focused growth strategy.

The company has built a concentrated acreage position within the SWISH Play in Oklahoma’s Anadarko Basin, where it has been progressively expanding its production base and reserve inventory.

Brookside describes its broader strategy as centred on increasing production, building operational scale and generating Capital returns over time through disciplined development activity.

The Anadarko Basin itself remains one of North America’s established oil and gas producing regions, containing multiple stacked formations that support horizontal drilling programs.

Brookside’s focus on repeatable multi-well development programs reflects the company’s strategy of applying operational consistency across its acreage portfolio.

The Sabres and Whalers development campaign forms part of this broader effort to extend production growth while maintaining operational efficiency.

Management Commentary Highlights Operational Momentum

Brookside Managing Director and CEO David Prentice stated that momentum within the SWISH AOI continues to build as the company transitions from site preparation into operational readiness.

According to management, the current stage of development represents another practical step in converting the company’s broader development plans into future production growth.

The company also emphasised that having the drilling location, contractors and infrastructure preparations aligned ahead of rig mobilisation should assist in keeping the program moving efficiently through each operational phase.

Management reiterated that the development campaign builds on the operational foundation already established across Brookside’s SWISH acreage.

The company further noted that the Sabres and Whalers wells align with its repeatable development model targeting both the Sycamore and Woodford formations.

What This Means for Investors

Brookside Energy’s latest operational update provides further visibility into the company’s upcoming drilling activities within its core SWISH AOI position in Oklahoma.

The market response suggests investors viewed the continued progress toward rig mobilisation and drilling readiness as a favourable operational milestone.

The completion of pad construction, conductor installation, vendor contracting and infrastructure work indicates that the company is moving steadily toward the next phase of development operations.

Investors are also likely monitoring the program because it is expected to contribute to future production, reserve and cash flow growth if drilling and completion activities progress as planned.

The Sabres and Whalers wells additionally represent another test of Brookside’s multi-well development strategy in the Anadarko Basin, where the company continues expanding its operated activity.

As operations move into drilling and completion phases, the market may continue focusing on future updates linked to production timing, first sales and overall well performance.
