Omega Oil & Gas is drilling ahead at the Canyon-3 appraisal well in Queensland’s Taroom Trough, targeting extensive Permian reservoirs that could define a significant new oil and gas province.
- Canyon-3 drilling on schedule, currently at 2,570m depth
- Targets laterally extensive, overpressured Permian sandstone reservoirs
- Aims to confirm a large new oil and gas province in eastern Taroom Trough
- Potential for 75 development wells over a 200km² area
- Results expected within two weeks to refine geological models
Canyon-3 Well Progress and Geological Target
Omega Oil & Gas Limited (ASX:OMA) is pressing forward with its Canyon-3 appraisal well, the first of its fully funded 2026/27 drilling campaign in Queensland’s Taroom Trough. Drilling is progressing on schedule, currently ahead at 2,570 metres in the intermediate hole section, with the top of the targeted Permian sandstone section expected around 3,200 metres and total depth planned near 3,900 metres. This well, situated 10 kilometres southeast of the earlier Canyon-1/1H well, is designed to test the lateral extent of a large oil and gas-bearing petroleum province.
Distinct Eastern Flank Reservoir Characteristics
The Canyon-3 well targets a geological setting on the eastern flank of the Taroom Trough that contrasts sharply with the western flank’s more variable reservoir quality. Here, Omega is focusing on laterally extensive, overpressured Permian sandstone reservoirs that have shown stacked oil and gas intervals in previous drilling. This eastern flank setting offers a more consistent reservoir presence, which could underpin a more reliable development scenario. The well’s results will provide critical data to refine Omega’s geological model and better understand reservoir distribution and thickness across the acreage.
Potential Scale of the New Oil and Gas Province
Integration of data from Canyon-3 and the upcoming Canyon-4 well with existing wells Canyon-1 and Canyon-2, alongside 2D seismic surveys, aims to establish clear evidence of the oil-bearing Canyon sandstone reservoir spanning approximately 200 square kilometres between Canyon-1, Canyon-2, and the Cabawin Oil Field. According to modelling by SLB, this single reservoir layer could support an inventory of about 75 development wells, each roughly 2,000 metres long and spaced at 1,000-metre intervals, suggesting a significant commercial opportunity.
Strategic Importance and Next Steps
Omega’s appraisal program is positioned to unlock what may be the largest new commercial oil and gas province in Australia in decades, with the eastern Taroom Trough emerging as a rare opportunity to secure domestic supplies of gas and liquid fuels. The Queensland Government’s support and proximity to existing infrastructure enhance the project’s appeal and potential speed to market. The company expects to receive the first important results from Canyon-3 within two weeks, which will be pivotal in guiding subsequent drilling and development decisions.
Omega’s CEO Trevor Brown emphasised the well’s role in improving understanding of the hydrocarbon distribution updip from Canyon-1, highlighting the company’s technical and operational expertise demonstrated in prior wells. The ongoing campaign builds on the momentum from Omega’s recent funding and strategic positioning in the basin, aiming to mature the resource base and confirm commercial flow potential.
Bottom Line?
Canyon-3’s imminent results will be a crucial milestone in assessing the scale and commercial viability of Queensland’s emerging oil and gas province.
Questions in the middle?
- Will Canyon-3 confirm the lateral extent of the reservoir as modelled?
- How might the eastern flank’s reservoir consistency influence development plans?
- What timeline can investors expect for follow-up drilling and potential production?
