Key Highlights

  • Combined gross production from the Sabres and Whalers wells has exceeded 1,200 barrels of oil equivalent per day over a 24-hour period.
  • Liquids account for about 78 percent of total production, according to the company.
  • The two-well development is tracking about 15 percent below the original authorisation for expenditure.
  • Both wells remain in flowback, with load recovery of about 20 percent each and peak rates not yet established.

Brookside Energy Limited (ASX:BRK) has provided an update on flowback and production from the Sabres and Whalers wells at its operated Suttles Pad in the SWISH Play, southern SCOOP area of the Anadarko Basin in Oklahoma, according to a news release dated 12 November 2026. The wells have been brought into production, taking the company's operated SWISH producing well count to eleven. Combined gross production has exceeded 1,200 barrels of oil equivalent per day over 24 hours.

Production and liquids mix

Liquids represent about 78 percent of total production. Production from both wells has increased since first sales as flowback and clean-up operations progress. The company says the two wells bring two further locations within its independently certified reserve base into production.

The wells are exhibiting different early profiles, which the company links to the contrasting characteristics of the two reservoirs. Sabres is completed in the Sycamore formation, while Whalers is in the Woodford. Peak production rates have not yet been established, and both wells remain in flowback with about 20 percent load recovery.

Cost performance and working interests

Current estimates indicate that the complete two-well development, including pad construction, drilling, completions and facilities, is tracking about 15 percent below the original authorisation for expenditure. Following final hearings and pooling, the company's working interests were confirmed at 72.4 percent in Sabres and 71.3 percent in Whalers, compared with approximately 70 percent previously reported.

Final Word

The Suttles Pad wells have reached more than 1,200 barrels of oil equivalent per day during early flowback, with costs below budget and a higher working interest. The sustained rate, the peak production level and the decline profile will only become clear once the wells have stabilised. Until then, the early production figures indicate the start of production rather than its long-term performance.
