Key Highlights

Canyon North-1 has reached a total depth of 4,700 metres measured depth in basement, making it the deepest well drilled in Queensland according to the company.
Gas influx from the unstimulated Muggleton Formation was flared at surface in a controlled manner, with no flow rates measured.
The Joint Venture extended the well beyond its planned depth of about 4,000 metres to fully penetrate the Muggleton Formation.
Wireline logging is the next step, with Canyon North-2 to follow immediately and flow testing of horizontal appraisal wells targeted for the first half of 2027.

Omega Oil & Gas Limited (ASX:OMA) has provided an operational update on the Canyon North-1 well in ATP 2081 in the Taroom Trough, Queensland. The Joint Venture comprises Omega with 45% and operatorship, Tri-Star E&P with 30% and Beach Energy with 25%. The company says the well has reached total depth after drilling was extended beyond its original planned depth.

Drilling Progress and the Decision to Deepen

Canyon North-1 reached total depth of 4,700 metres measured depth in basement, drilled using a H&P FlexRig 648. The original planned total depth was about 4,000 metres. The Joint Venture chose to continue deepening the well, based on the results recorded in the Muggleton Formation at Canyon-4, a well in Omega’s 100%-owned PCA 342, and on high gas shows recorded from deeper sections of Canyon North-1.

Since reaching total depth, gas influx into the wellbore while drilling the unstimulated Muggleton Formation has been flared off at surface. The company describes this as an observation made during drilling operations only. It states that no flow rates have been measured and that the flare should not be taken as an indication of future flow rates or commercial productivity. Omega also reports that pressures encountered are consistent with high pore pressures obtained in the Canyon-1H diagnostic fracture injection test (DFIT), which the company previously announced in January 2025.

Next Steps and Logging Program

Operations are focused on preparing the well for a comprehensive wireline suite across the entire Permian sequence, including the Canyon Sandstone and Lower Kianga Formation. If gas levels cannot be reduced sufficiently in the wellbore, the lower section will be plugged and the Muggleton Formation isolated. Wireline logging would then be undertaken over the remaining five regionally extensive reservoir levels. Results will be released once logging and evaluation are complete.

The indicative timetable is set out as follows. Canyon North-2 is to follow immediately after Canyon North-1. Core analysis results are expected to be incorporated into geological assessments during the fourth quarter of 2026 and the first quarter of 2027. An upgraded resource assessment is targeted for the first quarter of 2027. Following Canyon North-2, the company plans to drill at least one, and potentially two, horizontal appraisal wells across its operated acreage, with laterals of up to 2,000 metres and flow testing in the first half of 2027, subject to well results and Joint Venture approval.

Context from Company Announcements

The company refers to its earlier announcement of 12 October 2026 on Canyon-4, which it describes as its best Canyon well result to date. CEO and Managing Director Trevor Brown said the decision to take the well deeper has proven successful, and that gas influx from unstimulated rock at these depths in an over-pressured well supports the company’s view of a large, regionally extensive petroleum system in the Taroom Trough. Those statements are the company’s own assessment, and the company notes that the results and forward-looking statements are subject to uncertainties and risks.

Closing Perspective

The update describes drilling observations at total depth, with logging and evaluation still to come. Gas flaring during drilling is not a measure of commercial flow, and the company has stated that no flow rates have been established. The results of wireline logging, the Canyon North-2 drilling and the upgraded resource assessment will indicate how the observations translate into reservoir properties and into the planned appraisal and flow testing program.
