MCF Energy prepares for Welchau-1 well flow testing

2024-11-13 14:19 ET - News Release

Mr. Jim Hill reports

WELCHAU-1 PRODUCTION TESTING UPDATE

MCF Energy Ltd.'s preparations for flow testing the Welchau-1 well, located in the ADX-AT-II licence in Upper Austria, are progressing as planned.

Since mobilization of the Red Drilling & Services W-102 workover rig, together with ancillary equipment on Nov. 4 and Nov. 5, 2024, the workover rig has been set up on the Welchau-1 well and surface testing equipment as well as materials have been mobilized to the well site. The planned program is to test the 450 metres of hydrocarbon shows, starting with the two major reservoirs -- the deeper Steinalm formation and then the shallower Reifling formation.

A well completion assembly has been run in the well (tubing, packer and perforating system) and current operations include continuing well completion work in preparation for flow testing as well. Flow testing facilities are being installed and rigged up, which includes a test separator, the necessary pipework and production storage tanks.

Flow testing of the Steinalm formation will commence in approximately one week after well perforation as well as flow testing facilities rig-up, pressure testing of facilities and function testing.

Testing program

The environmental clearance is for continuous (24-hour) flow testing operations up to March 31, 2025. This allows provides the company with ample time to carry out an extensive testing program. This detailed flow testing is key and typical method industry wide for determining reservoir porosities and permeabilities carbonates reservoirs, which are often highly dependent on fractures.

A testing program has been developed focusing on the following objectives:

  • Determine reservoir fluid type present in key reservoirs;
  • Determine the flow capacity in key reservoirs;
  • Determine the reserves potential of the reservoirs.

The planned program includes the testing of the two major reservoirs of a total of four, starting with the deeper Steinalm formation and then the shallower Reifling formation. For each test, a number of flow periods and shut in periods are planned to determine the pressure response with downhole gauges. Well performance will be monitored to determine the potential reservoir damage from drilling and cementing of the well. In each test, the well may be stimulated, if necessary, to enhance well performance. Data collection during testing will include flow measurement, surface and downhole pressure measurement, as well as both surface and downhole sampling. The expected testing program duration for the Steinalm formation alone is between six and 10 weeks.

If good flow performance is achieved, the Steinalm test may be extended to obtain longer-term flow data. The workover rig used for the Welchau-1 test program was previously utilized at ADX Energy Ltd.'s Vienna basin fields and then for the completion of the successful oil Anshof-2A oil appraisal well. Together with other synergies for equipment and personnel, continued access to the work over rig gives the company the operational flexibility to vary the program without a significant increase in costs.

Background

The Welchau-1 well encountered hydrocarbon shows over a 450-metre interval intersecting three primary carbonate reservoirs that are considered promising for testing and continuing appraisal. The well was suspended for future evaluation on March 28, 2024, after running and cementing seven-inch casing. Operations were suspended to comply with the conditions of environmental permits limiting drilling and testing operations to the Austrian winter months from Oct. 1, 2023, to March 31, 2024.

Data recovered from the well during the drilling and evaluation phase included hydrocarbon shows, wellbore inflows, drilling mud losses, formation cuttings, petrophysical borehole log data, formation fluid sampling and formation coring. These data have been used to assess the potential of the Welchau discovery and design the planned test program.

On Sept. 26, 2024, the company announced that the hydrocarbons discovered at Welchau are likely to be a high-gravity (43.6-degree API) light oil with associated gas rather than a liquids-rich gas discovery as it was predicted prior to drilling.

Other exploration potential near Welchau-1

MCF Energy notes that there is exploration potential at the nearby and farther north of the Rossberg lead as well as the deeper potential at Welchau in reservoirs below the seven-inch casing at the well's total depth (1,733 metres) that have yet to be drilled.

Economic participation in the Welchau investment area

MCF has executed an energy investment agreement with ADX to finance 50 per cent of Welchau-1 well costs up to a well cost cap of 5.1 million euros to earn a 25-per-cent economic interest in the Welchau investment area, which is part of ADX Energy's ADX-AT-II licence in Upper Austria. The Welchau investment area contains the Welchau discovery well and other emerging oil and gas prospects. MCF has met its financing and earning obligations to ADX and it holds a 25-per-cent economic interest in the Welchau investment area with MCF obliged to pay 25 per cent of continuing well costs.

James Hill, chief executive officer and director of MCF Energy, stated: "We continue to move forward with the testing program at Welchau in Austria. I am very optimistic that this discovery could provide significant resources to Austria and increase the country's energy security. We expect to be providing many updates in the coming months as these projects proceed."
