Highlights

Canyon-4 intersected 197 metres of net pay within a 589-metre gross oil- and gas-bearing sequence.
Canyon North-1 drilling commenced on 21 October 2026 under the ATP 2081 joint venture.
Cash stood at approximately $92.9 million at 30 September 2026.
Canyon-4 drilling observations do not constitute a measured production flow rate.

Omega Oil & Gas Limited (ASX:OMA) explores and appraises oil and gas resources in Queensland’s Taroom Trough, with the Canyon Project central to its current activities. During October 2026, the company reported new reservoir measurements from Canyon-4 and commenced drilling at Canyon North-1. These activities extend its appraisal program while it assesses the geological and commercial characteristics of the petroleum system.

Canyon-4 Adds Reservoir Data

Omega Oil & Gas Limited (ASX:OMA) reported that Canyon-4 reached a total depth of 4,017 metres. The vertical appraisal well intersected 589 metres of gross oil- and gas-bearing Permian strata, including 197 metres of net pay. The comparable net-pay measurements cited for Canyon-3 and Canyon-1 were 170 metres and 132 metres, respectively. These measurements indicate differences in the intervals interpreted as potentially productive across the drilled locations; they are not production volumes.

The company reported average Canyon Sandstone porosity of 12.1% at Canyon-4, compared with 7.4% at Canyon-1. Core recovery was 94.6%. Canyon-4 is situated approximately eight kilometres south of Canyon-3 and about 100 metres structurally updip. Together, the measurements add geological information about reservoir thickness and rock characteristics across the appraisal area.

Canyon North Drilling Extends the Program

On 21 October 2026, Omega Oil & Gas Limited (ASX:OMA) commenced drilling Canyon North-1, the first well under the ATP 2081 joint venture. The company holds a 45% operated interest in the venture, alongside partners holding 30% and 25%. The well is located approximately six kilometres from the Tasmania-1 well and around 250 metres structurally updip.

Canyon North-1 forms part of the company’s 2026–27 drilling program. A further well, Canyon North-2, was planned for the December 2026 quarter. As with any appraisal campaign, the drilling sequence provides information progressively: results from one location do not establish the flow performance or commercial viability of another.

September Cash and Appraisal Expenditure

Omega Oil & Gas Limited (ASX:OMA) reported approximately $92.9 million in cash at 30 September 2026, compared with $102.1 million at 30 June 2026. The change occurred as the company progressed its multi-well appraisal campaign. Omega has described the 2026–27 program as funded, although the reported cash balance will continue to change as drilling, evaluation and related expenditure proceed.

The distinction between reservoir observations and measured well performance remains important. Canyon-4’s net-pay, porosity and hydrocarbon indications describe subsurface characteristics, but the supplied October update did not include a formal flow-test rate for that well. Flow testing and further technical evaluation would provide different evidence from drilling measurements alone.

Upcoming Technical Milestones

For Omega Oil & Gas Limited (ASX:OMA), the next reported well results, further appraisal drilling and planned 2027 testing are central milestones. The company has identified a resource assessment for the first quarter of 2027 and one or two horizontal wells with flow testing during the first half of 2027 as intended activities. These remain plans rather than completed results, and timing may change with operational conditions.

Key Insights

The 2026 Canyon appraisal campaign has expanded Omega’s geological dataset through Canyon-4 and the commencement of Canyon North-1. Reported cash at September quarter-end provides financial context for the ongoing program. Reservoir measurements, future drilling results and measured flow performance are separate stages in determining the project’s development characteristics.
