ADX Energy Ltd (ASX:ADX) has disclosed that its GA-093 production well in the Vienna Basin has flowed at an initial rate of 1.8 million standard cubic feet per day (MMSCFPD) through an 8mm choke following recompletion and perforation of a gas zone, with the well to be restricted to a sales gas rate of 0.6 MMSCFPD due to sales pipeline capacity constraints.

Key Points

  • GA-093 well flowed at an initial rate of 1.8 MMSCFPD through an 8mm choke after recompletion and gas zone perforation
  • Well restricted to 0.6 MMSCFPD, equivalent to 100 barrels of oil equivalent per day (BOEPD), due to sales pipeline capacity constraints
  • Incremental production represents approximately a 40% increase to ADX Austrian production, which averaged 242 BOEPD in the quarter ending 30 September 2026
  • Current European gas price is EUR 82.6 per MWh, equivalent to US$162 per barrel
  • HOCH-1 Phase 2 gas testing scheduled for the week commencing 7 December, with ADX holding a 50% economic interest in the HOCH gas discovery

GA-093 Well Recompletion Results and Sales Rate

The GA-093 production well, located at ADX's 100% owned Vienna Basin Fields in Austria, was recompleted using the MB Well Services workover rig. Following perforation of a gas zone, the well flowed at an initial rate of 1.8 MMSCFPD through an 8mm choke. The well will be restricted to a sales gas rate of 0.6 MMSCFPD, which is equivalent to an oil rate of 100 BOEPD. The filing states that 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.

Remaining Vienna Basin Well Work Program Schedule

ADX disclosed a schedule of further well work activities. A Vienna Basin oil well pump replacement is scheduled for the week commencing 16 November. The replacement of a downhole pump in the GA-072A production well is expected to deliver approximately 15 BOEPD of incremental oil and gas production. A Vienna Basin well new oil zone completion is scheduled for the week commencing 14 December, with perforation of a new production interval in the GA-087 well and installation of a sand retention completion expected to deliver approximately 30 to 40 BOPD of incremental oil production.

HOCH-1 Phase 2 Gas Testing Program

HOCH-1 Phase 2 gas testing is scheduled to commence the week of 7 December, with approximately two weeks of well work required at HOCH-1 prior to testing. The Phase 2 program will evaluate the Hall Channel zones, which have been mapped and correlated to nearby gas discoveries, indicating potential for a large lateral extension. ADX is the operator of the HOCH-1 well and holds a 50% economic interest in the HOCH gas discovery, located within the ADX-AT-I exploration licence in Upper Austria. Further updates will be provided as they become available, the filing stated.
