Omega Oil & Gas Drills Canyon-4 to Prove Reservoir Across 400km² Acreage
Key Takeaways
- Canyon-4 drilling is now underway, targeting approximately 3,900m depth and located 8km south of Canyon-3, with results expected around end of September 2026.
- Canyon-3 delivered 526m of oil and gas-bearing Permian interval with 170m aggregate net pay across six stacked reservoirs — 14% thicker and 55% higher average porosity than the Canyon-1 equivalent.
- Canyon Sandstone reservoir continuity has now been demonstrated over more than 40km, with Canyon-4 designed to extend that evidence across approximately 400km² within PCA Areas 342 and 343.
- Omega is fully funded for its 2026/27 programme, with a structured catalyst pipeline running through late 2026 — Canyon-4, Canyon North-1, Canyon North-2, and an updated resource assessment.
- Normalised production from Canyon-1H reached 987 BOPD and 1.45 MMscf/d, underpinning the commercial productivity case ahead of planned flow-tested horizontal wells with laterals up to 2,000m.
Canyon-4 drilling underway as Omega extends its Taroom Trough appraisal campaign
Omega Oil & Gas (ASX: OMA) has commenced drilling at Canyon-4, the second well in its fully funded 2026/27 appraisal programme. Located approximately 8km south of the recently completed Canyon-3 well, Canyon-4 is targeting a total measured depth of approximately 3,900m, with results expected around the end of September 2026.
The well is designed to test the continuity and quality of Permian oil and gas-bearing sandstone reservoirs across Omega’s acreage. With Canyon-3 having exceeded pre-drill expectations, this campaign is systematic appraisal of a petroleum system already demonstrating consistent results — not speculative exploration.

What Canyon-3 proved — and why Canyon-4 matters
Canyon-4’s importance is best understood through the lens of what Canyon-3 delivered. The preceding well set a high bar, and Canyon-4 is now positioned to extend that evidence further south.
Canyon-3 results set a high bar
Canyon-3 intersected a standout Permian interval with metrics that exceeded pre-drill expectations across several measures:
- 526m thick oil and gas-bearing Permian interval
- 170m aggregate net pay across six stacked, regionally correlatable reservoirs
- Canyon Sandstone primary target 14% thicker than the equivalent interval in Canyon-1
- 55% higher average porosity than the Canyon-1 equivalent
- An additional gas and condensate-bearing interval identified in the Lower Kianga Sandstone
The broader petroleum system case
Cumulative drilling across the campaign has now built a consistent body of evidence pointing to a petroleum system of meaningful scale:
- Six stacked hydrocarbon-bearing reservoir layers confirmed
- Canyon Sandstone reservoir continuity demonstrated over more than 40km
- Very high reservoir overpressure measured at 0.79 psi/ft in the Canyon Sandstone in Canyon-1H
- Normalised production rate from Canyon-1H of 987 BOPD and 1.45 MMscf/d (rate normalised for a 2,000m section)
Each new well adds a data point to this growing continuity case. Canyon-4 is not a standalone bet — it is the next step in a systematic programme already showing consistent results across the acreage.
Understanding stacked Permian reservoirs — why geology drives the value case here
Stacked reservoirs refer to multiple separate layers of hydrocarbon-bearing rock sitting on top of one another within the same geological column. Rather than a single pay zone, you have several — which means a well can potentially access multiple sources of oil or gas, increasing total resource volumes without requiring additional wells.
Overpressure refers to reservoir fluid pressure that is higher than normal for a given depth. In practical terms, that additional pressure helps push hydrocarbons to surface more readily, which can support stronger flow rates. Omega measured very high overpressure in the Canyon Sandstone at Canyon-1H, which is a positive indicator for productivity.
The Taroom Trough sits within Queensland’s Bowen Basin, an emerging oil and gas province that has attracted growing attention from explorers. Appraisal drilling — the type Omega is conducting — progressively de-risks a resource by confirming that what was found in one location is consistent and present across a broader area. With each well, the uncertainty around scale and quality reduces, and the investment thesis becomes better supported by data.
A pipeline of catalysts through to late 2026
Omega remains fully funded for its 2026/27 appraisal programme and retains flexibility to exercise further rig contract options as operational results warrant. For investors, what this creates is a structured pipeline of data-release events over the next several months.
Upcoming milestones — what to watch and when
- Canyon-4 results — expected around end of September 2026
- Canyon North-1 results — approximately one month after Canyon-4, subject to drilling progress
- Canyon North-2 results — approximately one month after Canyon North-1
- Updated resource assessment — anticipated late 2026
- One or two flow-tested horizontal wells with lateral lengths up to 2,000m — following the vertical appraisal programme
Canyon North-1 and Canyon North-2 are located in ATP 2081 and are subject to land access, well results, and Joint Venture approval.
The table below summarises the four vertical wells in the 2026/27 campaign:
| Well | Location/Area | Key Objective | Expected Timing | Status |
|---|---|---|---|---|
| Canyon-3 | PCA 342/343 | Permian reservoir continuity | Completed | Results released |
| Canyon-4 | ~8km south of Canyon-3, PCA 342/343 | Reservoir continuity and quality over ~400km² | End September 2026 | Drilling underway |
| Canyon North-1 | ATP 2081 | Extend resource evidence north | ~1 month after Canyon-4 | Planned |
| Canyon North-2 | ATP 2081 | Extend resource evidence north | ~2 months after Canyon-4 | Planned |
Integration of Canyon-4 results with existing well and seismic data is aimed at providing clear evidence of the Permian reservoir system across approximately 400km² within PCA Areas 342 and 343 — part of Omega’s 1,800km² total operated eastern Taroom Trough acreage.

CEO perspective — building toward a resource expansion
Trevor Brown, CEO and Managing Director, Omega Oil & Gas
“Canyon-4 is positioned to provide further evidence of the vast scale of the oil and gas resources across our eastern Taroom Trough acreage… We look forward to sharing Canyon-4 results around the end of September as we continue to systematically evaluate the huge commercial potential of our acreage and progress our assets.”
With the programme fully funded and a clear sequence of catalysts mapped out to late 2026, Omega’s appraisal strategy is built around systematically building the resource case across its acreage. The near-term focus is confirming Permian reservoir quality and continuity across approximately 400km² in PCA Areas 342 and 343, with the broader 1,800km² operated acreage representing the longer-term prize. An updated resource assessment is anticipated in late 2026, which would draw on the full dataset from the four-well vertical programme.
