MCF Energy Update of Welchau-1 Testing: Well recovers gas at surface during unloading operations
The 128-meter thick Reifling Formation is the shallowest of four carbonate reservoirs intersected at Welchau-1. The well was stimulated by pumping six (6) 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. 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.
These initial results of testing are encouraging for the following reasons:
- The recovered well fluids include a hydrocarbon gas (methane) monitored at surface.
- The hydrocarbon recovery is the first from the Reifling Formation from within the Welchau anticline or the basin, and
- A relatively small amount of acid used for the stimulation of the Reifling Formation has resulted in flow from a previously unresponsive reservoir.
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. 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.
It should be noted that well work over operations are twelve hours per day during week days.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. The Reifling Formation is interpreted to be at or near the oil water contact for a light oil accumulation in the Welchau anticline which is mapped approximately 500 metres updip of the Welchau 1 well (refer to Figure 1 and 2).
The Welchau-1 well is located in the Northern Calcareous Alps hydrocarbon fairway. It was drilled to test gas and condensate potential within the Middle Triassic fractured carbonate reservoir sequences below the Triassic Lunz-Partnach regional seal complex. The well drilled through a hydrocarbon-bearing complex fractured carbonate reservoir interval with continuous hydrocarbon shows.
