ADX Energy Ltd.: ADX HOCH-1 Well Operations Update
Wien (pta018/28.04.2026/09:46 UTC+2)
"HOCH-1 is the first of three shallow gas prospects to be drilled in Upper Austria. Two additional gas prospects are permitted for drilling in 2026."
Key points:
- The Hochfeld-1 ("HOCH-1") shallow gas exploration well commenced drilling on 16th of April 2026 at 9.00 pm CET in the ADX-AT-I exploration licence in Upper Austria.
- Operations at 6.00 am CET on the 27th of April 2026 were drilling ahead in 8 ½ inch hole at a measured depth ("MD") of 398 metres.
- Drilling operations since the last report were delayed due to severe mud losses in a gravel package at approximately 100 metres well depth. It was not possible to cure the losses with cement plugs. It was necessary to redrill the hole with a larger 12 ¼ inch hole size and run 9 5/8 inch casing to 111 metres to isolate the lost circulation zone before drilling ahead in 8 ½ inch hole.
- Future operations are drilling ahead in 8 ½ inch hole section TD of 430 metres, then running and cementing 7 inch casing. After cementing the 7 inch casing the well will be drilled to a total depth of approximately 1430 metres MD in 6 1/8 inch hole before running wire line logs. The time to reach well TD is approximately 7 days and wireline logging will be completed one to two days later.
- The HOCH-1 well is targeting highly productive shallow gas reservoirs within Miocene aged sandstones of the Hall formation. Similar Hall formation wells have recorded initial production rates of up to 9 mmscf/d (approx. 1,500 bpd oil equivalent).
- The HOCH prospect has a Mean Prospective Resource* potential of 8.0 BCF and a High Case Prospective Resource of 17.3 BCF (Refer to Prospective Resources Estimate, Figure 4 in the attached Appendix and ASX release dated 30 January 2026).
* Prospective Resources are those estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both a risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially recoverable hydrocarbons.
