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

MCF Energy Ltd. (TSXV: MCF) (FRA: DC6) (OTCQX: MCFNF) is pleased to report initial results from the resumption of testing of the Reifling Formation at the Welchau-1 well in Austria. MCF holds a 25% economic interest in the Welchau project, with ADX Energy (ADX) as the operator with the remaining 75% interest.

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:

1. The recovered well fluids include a hydrocarbon gas (methane) monitored at surface.
2. The hydrocarbon recovery is the first from the Reifling Formation from within the Welchau anticline or the basin, and
3. 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.

In addition, and without limiting the generality of the foregoing, this press release contains forward-looking information regarding the anticipated timing of development plans and resource potential with respect to the Company's right to assets in Germany. Forward-looking information typically uses words such as "anticipate", "believe", "project", "expect", "goal", "plan", "intend" or similar words suggesting future outcomes, statements that actions, events or conditions "may", "would", "could" or "will" be taken or occur in the future.

The forward-looking information is based on certain key expectations and assumptions made by MCF Energy's management, including expectations and assumptions noted subsequently in this press release under oil and gas advisories, and in addition with respect to prevailing commodity prices which may differ materially from the price forecasts applicable at the time of the respective Resource Audits conducted by Gaffney Cline Associates, and differentials, exchange rates, interest rates, applicable royalty rates and tax laws; future production rates and estimates of operating costs; performance of future wells; resource volumes; anticipated timing and results of capital expenditures; the success obtained in drilling new wells; the sufficiency of budgeted capital expenditures in carrying out planned activities; the timing, location and extent of future drilling operations; the state of the economy and the exploration and production business; results of operations; performance; business prospects and opportunities; the availability and cost of financing, labour and services; the impact of increasing competition; the ability to efficiently integrate assets and employees acquired through acquisitions, the ability to market natural gas successfully and MCF's ability to access capital. Although the Company believes that the expectations and assumptions on which such forward-looking information is based are reasonable, undue reliance should not be placed on the forward-looking information because MCF Energy can give no assurance that they will prove to be correct. Since forward-looking information addresses future events and conditions, by its very nature they involve inherent risks and uncertainties. MCF Energy's actual results, performance or achievement could differ materially from those expressed in, or implied by, the forward-looking information and, accordingly, no assurance can be given that any of the events anticipated by the forward-looking information will transpire or occur, or if any of them do so, what benefits that we will derive therefrom.
