In the greenhouse area of Paradajz, d.o.o. a well Re-1g was designed in 2011 to extract thermal water from the permeable layers of the lower Mura Formation. The Fi-5 well is a former well that today serves as a measurement well - reaching up to a depth of about 2400 m. To obtain thermal water from the Re-1g well, the company was granted a concession to use the thermal water from the well. The maximum permissible total annual volume of borehole water use was 236,520 m3/year until 2019 and from 2019 onwards 336,520 m3/year, while the maximum permissible total instantaneous groundwater volume of the well is 20,0 l/s.
The Re-1g well is located in the area of Renkovci – massif of Murska Sobota, which, in addition to Maribor-Radgona depression, Ptuj-Ljutomer depression and Ormož-Seniška anticline, make up the Mura depression. All four tectonic units differ significantly in terms of sediment thickness, type and age of tertiary sediments, and tertiary elongation and tectonic conditions.
The Fi-5 well is located southeast of Murska Sobota in the Filovci structure, which also belongs to the massif of Murska Sobota. The Fi-5 well is a former well that has been saturated with oil, gas and water, today is used as a measuring well
The aim of the master's thesis is to determine the fluid-dynamic and thermal parameters of sand layers in the area of the Re-1g geothermal well. Based on the data of logging measurements, pumping measurements, hydraulic pressures and temperatures in groundwater levels in the deep wells Re-1g and Fi-5, we will try to determine the permeability of the layer and its compression properties. At both wells we will measure and compare pressures and temperatures, and at well Re-1g also the flow of water.
