Omega Oil & Gas has unveiled exceptionally strong results from its Canyon-3 well, revealing a thick, high-quality oil and gas-bearing Permian interval that significantly expands the scale of its resource base in Queensland’s Taroom Trough.
- Canyon-3 well reveals 526m thick hydrocarbon-bearing interval with 170m net pay
- Canyon Sandstone shows 14% thickness and 55% higher porosity than previous well
- Evidence supports continuous, regionally extensive oil and gas system
- Next drilling phase to start with Canyon-4 well in days
- Fully funded 2026/27 appraisal program includes multiple vertical and horizontal wells
Canyon-3 Well Exceeds Expectations with Thick Oil and Gas Reservoirs
Omega Oil & Gas Limited (ASX:OMA) has delivered a major boost to its Queensland Taroom Trough exploration campaign with the Canyon-3 well confirming a large, oil and gas-bearing Permian interval that far surpasses earlier estimates. The well reached a total depth of 3,792.6 metres, revealing a 526-metre thick hydrocarbon interval containing an aggregate net pay of 170 metres. Notably, the primary target, the Canyon Sandstone, was found to be 14% thicker and exhibited 55% better porosity compared to the original Canyon-1 well, with 18 metres of net oil-bearing sands averaging 11.5% porosity within a 42-metre gross reservoir interval.
Expanding the Known Oil and Gas Province in the Taroom Trough
The Canyon-3 results provide compelling evidence of a continuous and regionally extensive hydrocarbon system in the eastern Taroom Trough, extending at least 20 kilometres east-west towards the Cabawin Oil Field. Regional data further suggest the Canyon Sandstone spans more than 40 kilometres north-south and beyond, reinforcing Omega's interpretation of a large-scale, commercially significant oil and gas province. This well data, combined with seismic and petrophysical analysis, enhances understanding of six stacked Permian reservoirs and their hydrocarbon saturation, with indications of overpressure that could support repeatable commercial flow rates.
Pathway to Commercial Development and Resource Maturation
Omega’s 2026/27 appraisal program is designed to establish the scale and commercial potential of these resources. The company plans to drill four vertical wells followed by one or two horizontal wells with flow tests to better define reservoir continuity and fluid distribution. The upcoming Canyon-4 well is scheduled to commence shortly after a rig move, continuing the campaign that is fully funded and supported by multiple rig options. Modelling based on Canyon-1 and Canyon-1H data suggests that a single 2,000-metre horizontal well could deliver an estimated ultimate recovery of approximately 0.95 million barrels of oil equivalent (MMBOE) over 10 years, implying a robust inventory of development wells across the prospective area.
Technical Insights and Hydrocarbon Distribution
Advanced surface logging and wireline data from Canyon-3 have confirmed the presence of oil fluorescence across all six reservoir intervals, providing visual confirmation of hydrocarbons. The well also encountered an additional high-quality gas and condensate-bearing reservoir interval, the Lower Kianga Sandstone, with enhanced properties compared to previous wells. These findings refine Omega’s geological model and support the identification of zones with the most favourable reservoir quality and hydrocarbon saturation, critical for future commercialisation strategies.
Next Steps in the Drilling Campaign
With Canyon-3 data now integrated into the company’s existing datasets, Omega is poised to reduce subsurface uncertainties and mature its resource base. The rig is moving to the Canyon-4 well location to continue the appraisal program, with further updates anticipated as drilling progresses. The company’s strong cash position and technical expertise underpin its confidence in unlocking the Taroom Trough’s potential as a key contributor to Australia’s energy future.
Bottom Line?
Omega’s Canyon-3 results mark a pivotal step in confirming a major oil and gas province, but upcoming flow tests and further drilling will be crucial to validate commercial viability.
Questions in the middle?
- How will flow test results from upcoming horizontal wells influence resource valuation?
- To what extent will the enhanced reservoir properties in Lower Kianga Sandstone impact development plans?
- Can Omega maintain operational momentum and funding through the full 2026/27 appraisal program?
