HOCH-1 is the first of three shallow gas prospects 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. Operations at 6.00 am CET on the 19th of April 2026 were drilling ahead in 8 ½ inch hole at a measured depth (“MD”) of 96 metres. Future operations are drilling ahead to 430 metres, then running and cementing 7 inch casing (refer to Well Plan, Figure 5 in attached appendix).
- HOCH-1 will be drilled to a depth of approximately 1430 metres MD and will take approximately 14 days to drill and evaluate. The HOCH-1 well will target 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).
ADX Energy has advised the commencement of drilling of the Hochfeld-1 ('HOCH-1') well with the MND Drilling & Services MD-150 drilling rig on the 16th of April 2026 at 9.00 pm CET. Operations at 6.00 am CET on the 19th of April 2026 were drilling ahead in 8 ½ inch hole at a measured depth (“MD”) of 96 metres.
The HOCH-1 shallow gas exploration well will be drilled in the ADX-AT-I exploration licence in Upper Austria (refer Figure 1 in the attached Appendix). ADX is the operator and holds a 50% economic interest in the HOCH prospect.
The HOCH-1 well is expected to take approximately fourteen (14) days to drill and evaluate assuming a success case scenario. A successful well will be cased and suspended for production testing to determine the reserves potential. The total measured depth (“MD”) is approximately 1430 metres with a true vertical depth (“TVD”) of 1145 metres.
Future Operations
Future operations are drilling ahead to 430 metres, then running and cementing 7inch casing (refer to Well Plan, Figure 5 in attached appendix).
