ADX Energy (ASX:ADX) reports Vienna Basin gas flow as Austrian well program advances
ADX Energy has reported gas flow from a recompleted production well at its 100% owned Vienna Basin Fields in Austria, with sales pipeline capacity constraining the rate available for production.
The result comes as the company undertakes a well work program covering production enhancement activities and further testing of its HOCH gas discovery in Upper Austria.
Highlights
GA-093 flowed at an initial rate of 1.8 MMSCFPD through an 8mm choke following recompletion and perforation of a gas zone.
Pipeline capacity will restrict sales gas production to 0.6 MMSCFPD, equivalent to 100 BOEPD.
The incremental production represents approximately a 40% increase against Austrian production averaging 242 BOEPD during the quarter ending 30 September 2026.
Further work includes pump replacement, completion of a new oil production interval and Phase 2 testing at HOCH-1.
The program is using the MB Well Services workover rig, with the remaining activities scheduled through November and December.
Within the Vienna Basin Fields, ADX has identified expected incremental production from work on existing wells, while the HOCH-1 program will evaluate slightly deeper gas reservoirs within the ADX-AT-I exploration licence.
The announcement places the timing of the work against high European gas prices and strong demand during the winter months, reporting a current European gas price of EUR 82.6 per MWh, equivalent to an oil price of US$162 per barrel.
As the announcement states:
“Undertaking the work at this time will generate elevated incremental cash flow due to high gas prices and strong gas demand during winter months in Europe.”
The next scheduled Vienna Basin activity is replacement of a downhole pump in the GA-072A production well during the week commencing 16 November, which ADX expects to deliver approximately 15 BOEPD of incremental oil and gas production.
Work on GA-087 is scheduled for the week commencing 14 December and involves perforation of a new production interval alongside installation of a sand retention completion, with expected incremental oil production of approximately 30 to 40 BOPD.
Separately, ADX operates the HOCH gas discovery and holds a 50% economic interest, with Phase 2 gas testing at HOCH-1 scheduled for the week commencing 7 December.
Approximately 2 weeks of well work is required before testing, including removal of the current completion, drilling out a cement plug to access the deeper reservoir and installation of a production completion before perforation.
HOCH-1 encountered up to 8 biogenic gas reservoirs within the Hall basin floor fan formation and Base Hall Channel formation, while Phase 1 testing recorded a commingled flow rate of 3.15 MMCFPD from 4 reservoirs, equivalent to 548 BOEPD.
The next testing phase will evaluate the Hall Channel zones, which have been mapped and correlated with nearby gas discoveries.
According to the release, those correlations indicate potential for a large lateral extension and resource potential, with the interpretation further supported by reserves data from nearby Hall Channel production wells.
The remaining program covers both the Vienna Basin production enhancement activities and evaluation of the HOCH-1 Hall Channel Zone #6 reservoir, with ADX to provide further updates as work and testing results become available.
