MCF Energy Update of Welchau-1 Testing: Well recovers gas at surface during unloading operations

Executive Summary

• MCF Energy reported initial positive results from resumed testing of the Reifling Formation in the Welchau‑1 well, including surface recovery of methane gas.
• This marks the first hydrocarbon recovery from the Reifling Formation within the Welchau anticline or basin.
• Ongoing swabbing and pressure measurements will determine if continuous production can be achieved.

Key Details

• Welchau‑1 is a 25% economic interest held by MCF Energy; ADX Energy operates the project (75% interest).
• The Reifling Formation is ~128 m thick, the shallowest of four carbonate reservoirs intersected at the well.
• Stimulation involved pumping 6 cubic meters of acid followed by completion brine; acid was allowed to soak before flow‑back.
• Swabbing the well unloaded hydrostatic brine, resulting in surface flow of brine, methane gas, and CO₂ (the latter from acid–carbonate reaction).
• Initial testing confirmed:
• Presence of methane at surface – first hydrocarbon recovery from this formation in the area.
• Successful flow after a relatively small acid volume, indicating responsiveness of a previously unproductive reservoir.
• Current well status: shut‑in pending resumption of swabbing operations; work‑over activities run ~12 hours per day on weekdays.
• Planned next steps:
• Additional swabbing to clean the well and target continuous oil/gas flow.
• Sampling of produced fluids for hydrocarbon content/type analysis.
• Bore pressure measurements to verify connectivity of Reifling Formation with the broader Welchau anticline.
• If sustained production is achieved, measurement of well flow rate will be performed.
• Geological context: Welchau‑1 targets gas and condensate potential in Middle Triassic fractured carbonate sequences beneath the Lunz‑Partnach seal; intersected a hydrocarbon‑bearing fractured carbonate interval with continuous shows.
