Austrian oil & gas giant OMV has conducted a production and injection test in fall 2022 to analyze the geothermal potential in the Vienna Basin, Lower Austria. The test took place in the basement of the Vienna Basin, in the “Hauptdolomit”. A workover prepared the OMV well Aderklaa 96 for testing at a depth of about 2,900 m. Formation water was produced, temporarily stored above ground in sealed containers, and then fed back into the formation. The aim of the geothermal test was to determine important reservoir parameters and to obtain samples of the formation water in order to decide whether this formation is suitable for producing geothermal energy for direct heat use. The actual testing has been completed and the testing facility is being dismantled again. The OMV experts are satisfied with the initial results: Water could be produced with temperatures of 102 degrees Celsius at a rate of up to 40 cubic meter per hour and has been reinjected successfully. In the coming months, the next step is to analyze various parameters of the data obtained to check the technical feasibility and subsequently the economic viability.In its Strategy 2030, OMV, the international integrated oil, gas and chemicals company headquartered in Vienna, has set itself the goal of expanding its low carbon business and thereby its range of low carbon energy. OMV’s energy production from geothermal energy is expected to grow to up to 9 TWh by 2030.
