Brookside Energy’s two new Suttles Pad wells have exceeded 1,200 BOEPD in combined gross production, with liquids making up about 78% of output. The wells remain in flowback, but the development is tracking 15% below its original AFE.
- Sabres and Whalers exceed 1,200 BOEPD combined gross production

- Confirmed working interests rise to 72.4% and 71.3%
Suttles production clears 1,200 BOEPD
Brookside Energy Limited (ASX:BRK) has reached an early operational milestone at its Suttles Pad, with the Sabres and Whalers wells producing more than 1,200 barrels of oil equivalent per day combined over a 24-hour period.
The result arrives only weeks after the company began first sales from the wells. The pair now takes Brookside’s operated SWISH producing well count to 11, following the Suttles wells first sales. Liquids account for approximately 78% of the reported output, although the company’s BOE calculation includes estimated natural gas liquids and converted gas volumes under stated assumptions.
Development costs track below the original AFE
The other notable number is on the cost side: the complete two-well development, covering pad construction, drilling, completions and facilities, is tracking approximately 15% below its original authorisation for expenditure. Brookside described the combination of lower development costs and rising production as an encouraging early indication of the pad’s economics.
That assessment is not yet a settled production case. Both wells remain in flowback and clean-up, with load recovery estimated at about 20% for each well. Peak production rates have not been established, meaning the current figure is an early operating snapshot rather than a demonstrated steady-state rate.
Different reservoirs produce different early profiles
Sabres, targeting the Sycamore formation, and Whalers, targeting the Woodford, are showing different early production profiles. Brookside said that divergence was expected because the reservoirs have contrasting characteristics, but provided no well-by-well production split or stabilised-rate guidance.
The update also confirms slightly higher working interests than previously reported: 72.4% in Sabres and 71.3% in Whalers, after final Oklahoma Corporation Commission hearings and completion of mop-up pooling. The wells followed the Suttles completion program, which included planned stimulation work across the two laterals.
Stable rates will determine the next read
For Brookside, the immediate test is whether production holds as flowback ends and the wells move towards more representative operating rates. The next useful evidence will be stabilised output, decline behaviour, realised liquids and gas pricing, and operating costs alongside any later reserve or economic update.
Bottom Line?
The early Suttles numbers are encouraging, but the investment case still depends on what remains after flowback and clean-up are complete.
Questions in the middle?
- What production rates will Sabres and Whalers achieve once flowback is complete?
- How will the two reservoirs’ different early profiles translate into decline rates and recoveries?
- Will the 15% development cost saving persist once the pad reaches normal operating conditions?
