	abstract = {The Upper Pannonian (UP) sandstone formation has been utilised for thermal water production in Hungary for several decades. Although sustainable utilisation requires the reinjection of cooled geothermal brine into the host rock, only a fraction of the used water is reinjected in the country. UP sandstone formation is reported to exhibit low injectivity, making reinjection challenging, and its petrophysical properties are poorly known, which increases uncertainty in designing operational parameters. The goal of the study is to provide experimental data and to gain a better understanding of formation characteristics that control injectivity and productivity issues in Upper Pannonian sandstone layers. Petrographical characterisation and petrophysical laboratory experiments are conducted on cores retrieved from two wells drilled in the framework of an R&D project at the depth of between 1750 m and 2000 m. The experiments, such as grain density, porosity, permeability, and ultrasonic velocity, as well as thin section, grain size distribution, XRD, and SEM analyses, are used to determine Petrophysical Rock Types (PRT) that share distinct hydraulic (flow zone indicator, FZI) and petrophysical characteristics. These are used to identify well intervals with lower potential for injectivity issues. The results imply that fines migration due to formation erosion is one of the key processes that must be better understood and controlled in order to mitigate injectivity issues at the study area. Future investigation should include numerical and experimental characterisation of formation damage, including water–rock interaction tests, critical flow velocity measurements, and fines migration analysis under reservoir conditions.},

	abstract = {Our recent knowledge about the role of different fluid driving forces in the response of groundwater flow systems to climate change is still limited. This current study aimed to evaluate possible spatial and temporal changes in complex, gravity- and overpressure-driven groundwater flow systems induced by climate change and look for general trends and characteristics of the flow field using 2D transient groundwater flow simulations. Results showed significant large-scale changes in the transient subsurface flow field and flow dynamics due to recharge reduction. Local gravity-driven flow systems are the most vulnerable to atmospheric processes, while overpressured regimes are expected to be independent of direct climatic variability. By the involvement of different degrees of overpressure, it was revealed that, as the degree of overpressure increases, the penetration depth of the topography-driven local flow systems decreases. The higher the overpressure, the lower the climate change-induced groundwater level decrease over time, suggesting the buffering effect of overpressure as a fluid driving force in the flow systems’ response to the changes in hydrologic parameters. The main novelty of the study is the involvement of different fluid driving forces in the evaluation with the combination of a regional scale investigation, which is unique in the context of climate change effects on groundwater systems.},
