20.500.12556/RUL-183962 Določitev prepustnosti in ocena povezljivosti geotermalnega vodonosnika v Moravskih Toplicah magistrsko delo Determination of permeability and assessment of connectivity of the geothermal aquifer in Moravske Toplice master's thesis Terme 3000 Moravske Toplice ležijo v severovzhodni Sloveniji in so eno večjih središč zdraviliškega turizma. Termalna voda na tem območju izteka iz hidravlično zaprtega geotermalnega vodonosnika. Za potrebe Term 3000 imajo od leta 2015 koncesijsko pogodbo za pridobivanje podzemne vode iz vrtin Mt-1/60, Mt-4/74, Mt-6/83 in Mt-7/93, medtem ko se vrtina Mt-5/82 uporablja kot opazovalna. Termalno vodo v Moravskih Toplicah izkoriščajo tudi v Termah Vivat, ki pridobivajo vodo iz vrtine Mt-8g/05. Obravnavani podatki zajemajo obdobje med januarjem 2024 in aprilom 2025 ter vključujejo merjene pretoke iz črpalnih vrtin Mt-6/83 in Mt-7/93 ter spremembe gladine podzemne vode v najnovejši reinjekcijski, ki zaenkrat služi kot opazovalna vrtina Mt-9/23. Za oceno hidravličnih parametrov so bili uporabljeni kvazi-interferenčni preizkusi, pri katerih se je spremljal odziv gladine podzemne vode v opazovalni vrtini na povečanje črpanja v črpalnih vrtinah. Transmisivnost je bila določena z analitičnima pristopoma po Theisu in Cooper-Jacobu, pri čemer so rezultati pokazali dobro skladnost med metodama, saj sta obe metodi podali rezultate v istem velikostnem razredu. Na podlagi dobljenih transmisivnosti smo izračunali koeficient prepustnosti za štiri scenarije, ki upoštevajo različne debeline vodonosnika: dolžina filtrskega odseka, skupna dolžina odprtih filtrskih odsekov, skupna debelina peščenih teles znotraj deltnega čela Murske formacije in celotna debelina Murske formacije. Kot najbolj reprezentativen se je izkazal scenarij, ki upošteva debelino peščenih teles (K = 3,68 x 10-5 m/s), saj najbolje odraža hidravlično obnašanje vodonosnika na regionalnem nivoju. Analiza povezljivosti je pokazala dobro hidravlično povezanost med obravnavanimi vrtinami na razdaljah do najmanj enega kilometra. Kljub temu heterogenost vodonosnika povzroča lokalne razlike v intenzivnosti odziva. Rezultati potrjujejo, da Murska formacije predstavlja hidravlično odziven geotermalni vodonosnik, kar ob ustrezni rabi omogoča učinkovito in trajnostno rabo termalne vode na območju Moravskih Toplic. Ugotovitve tako prispevajo k boljšemu razumevanju hidravličnega obnašanja vrtin in podpirajo nadaljnje načrtovanje reinjekcije. Terme 3000 Moravske Toplice are located in northeastern Slovenia and are one of the larger centres of spa tourism. The thermal water in this area flows from a hydraulically confined geothermal aquifer. Since 2015, Terme 3000 have held a concession agreement for abstracting groundwater from wells Mt-1/60, Mt-4/74, Mt-6/83 and Mt-7/93, while well Mt-5/82 is used as an observation well. Thermal water in Moravske Toplice is also exploited by Terme Vivat, which obtain water from well Mt-8g/05. The analysed data cover the period between January 2024 and April 2025 and include measured pumping rates from wells Mt-6/83 and Mt-7/93, as well as groundwater level changes in the newest reinjection well, which currently serves as an observation well, Mt-9/23. To estimate hydraulic parameters, quasi-interference tests were used, monitoring the groundwater level response in the observation well to increased pumping in the production wells. Transmissivity was determined using the analytical approaches of Theis and Cooper–Jacob. The results showed good agreement between the two methods, as both yielded values within the same order of magnitude. Based on the obtained transmissivities, the hydraulic conductivity was calculated for four scenarios that consider different aquifer thicknesses: the length of the screened interval, the total length of open screened intervals, the total thickness of sandy bodies within the delta-front of the Mura Formation, and the full thickness of the Mura Formation. The scenario considering the thickness of the sandy bodies (K = 3.68 × 10⁻⁵ m/s) proved to be the most representative, as it best reflects the hydraulic behaviour of the aquifer at the regional scale. Connectivity analysis indicated good hydraulic connection between the studied wells at distances of at least one kilometre. Nevertheless, aquifer heterogeneity causes local variations in response intensity. The results confirm that the Mura Formation represents a hydraulically responsive geothermal aquifer, which—when managed appropriately—allows for efficient and sustainable use of thermal water in the Moravske Toplice area. The findings contribute to a better understanding of the hydraulic behaviour of the wells and support further reinjection planning.Key words: Moravske Toplice, interference test, pumping test, thermal water, geothermal energy.
