08:39 AM EST, 02/17/2026 (MT Newswires) -- MCF Energy ( MCFNF ) on Monday reported initial results from the resumption of testing of the Reifling Formation at the Welchau-1 well in Austria.

In a statement the company noted that the 128-meter thick Reifling Formation is the shallowest of four carbonate reservoirs intersected at Welchau-1. It added that the well was stimulated by pumping six cubic meters of acid followed by a completion brine volume into the well ensuring that all the acid was injected into the reservoir and allowed to soak before the well was flowed back.

"To initiate flow in the well it was necessary to unload the hydrostatic column of brine by swabbing the well," said the company. "Swabbing resulted in brine, methane gas and CO2 being flowed to surface. The CO2 was the result of a reaction between the injected acid and the carbonate reservoir."

The company stated that the ongoing testing operations will include further swabbing to clean up the well with a view to achieving continuous flow of oil, gas or oil and gas. Produced fluids will be sampled to determine hydrocarbon content and type, said the company.

MCF Energy ( MCFNF ) added that well bore pressure measurements will be taken to confirm the pressure connectivity of the Reifling Formation with the remainder of the Welchau anticline. If continuous production is established the well flow rate will be measured, added the company.

It said that the well is currently shut in until swabbing operations resume.

"The primary testing objectives are to determine the hydrocarbon content and flow characteristics of the Reifling formation," added the company.

A statement noted that MCF holds a 25% economic interest in the Welchau project, with ADX Energy (ADX) as the operator with the remaining 75% interest.
