ADX Energy Ltd (ASX:ADX) Reports Progress on Welchau-1 Testing

Operations Update

ADX Energy Ltd (ASX:ADX) provided an update on the production testing of the Welchau-1 well. The results show that perforation of the upper part of the Reifling formation has not yet yielded sufficient flow to assess the reservoir fluid composition.

The testing has resulted in the recovery of black solid particles, classified as “Solid Contaminants,” which may hinder well flow. Additional flow analysis and sampling are planned to evaluate the situation further before deciding on reservoir acidization.

Well Testing Details

The company holds a 75% economic interest in the Welchau Investment Area, including the Welchau discovery, located in the ADX-AT-II licence in Upper Austria. The RED Drilling & Services W-102 workover rig has been employed to install necessary well completions for testing.

Following the earlier testing of the Triassic Steinalm formation, the upper section of the Reifling formation was perforated on November 28, 2024. Of three intervals perforated, limited inflow was noted, with only completion brine and the previously mentioned solid particles present. The well has been closed to observe potential natural flow and is awaiting a thorough analysis of the fluid composition.

Future Program Planning

The forward program for the Welchau-1 well will be developed following the collection and assessment of further well flow information. This may include options for reservoir acidization to enhance productivity in the carbonate reservoirs.

Ian Tchacos, Executive Chairman of ADX Energy Ltd, stated, “The results from the ongoing testing of the Welchau-1 well are critical as we work towards understanding the reservoir’s capability and planning our next steps.”
