Summary: Geothermal energy is an important source of renewable energy, providing stable and secure electricity and heat production. In Croatia, the development of geothermal energy is closely linked to the oil industry, as geothermal deposits were discovered during oil and gas exploration. This research aims to determine the heat potential of the Croatian part of the Pannonian Basin System (CPBS) by analyzing well data.

Summary: The Wagner basin in the northern Gulf of California has the potential for geothermal energy. Through seismic and heat flow surveys, researchers have found relatively high heat flow and large variability in the basin, which is believed to be caused by upward fluid flow along the Wagner fault zone. In contrast, the western flank of the basin has lower heat flow, suggesting conductive heat transfer without faults.

Summary: This research identifies the geothermal characteristics and control factors of the Gulf of Suez, and determines areas with high geothermal potential through three-dimensional interpolation of temperature, geothermal gradient, and heat flux borehole data. It also highlights the influence of faults on the geothermal resource and provides insights for efficient management of binary power generation and enhanced geothermal systems in the region.

Summary: The recently discovered Alarc'on Rise (AR) hydrothermal system in the Southern Gulf of California is characterized by black smokers, high-temperature fluids, metalsulfides, and H2S. Through isotopic signatures, the study determined the trophic structure and energy flow in the vent community, revealing a wide range of carbon sources, the position of different fauna in the food chain based on nitrogen isotopes, and the assimilation of sulfur in vent fauna and organic matter in non-vent organisms indicated by sulfur isotopes.

Summary: This study quantifies the stored energy in different geological units in the subsurface of Hesse, Germany, and demonstrates how conductive, advective, and convective heat transport mechanisms affect the thermal field. The results show that the highest deep geothermal potential is found in the Cenozoic unit of the northern Upper Rhine Graben and the Rotliegend layer.

Summary: Engineering case studies have shown that multi-well enhanced geothermal system is effective for large-scale geothermal energy utilization. However, there is currently a lack of fast and accurate prediction method for the productivity and lifespan of this system. To address this, a new empirical formula based on numerical simulation and previous formulas for double-well enhanced geothermal systems is proposed. The formula is tested in the Rehai geothermal field and the results indicate higher heat production and lifespan with six wells compared to three wells arrangement. Additionally, the productivity and lifespan are better with lower injection pressure and temperature of the thermal medium. This research provides a valuable prediction method for evaluating the heat transfer performance of large-scale multi-well EGS, beneficial for commercial use.

Summary: A novel enhanced super-long heat pipe system (ESLHPS) is proposed to improve the heat transfer rate and thermal performance of the super-long gravity heat pipe (SLGHP) in a single-well geothermal system. An insulation layer is set around the heat pipe to reduce heat loss. The thermal performance of the ESLHPS is found to be dependent on the thermal conductivity, length, and radius of the heat transfer enhanced region.

Summary: Fixed-plane-perforation fracturing (PFFP) has been introduced to enhance geothermal system (EGS) and has shown potential to stimulate longer fractures and achieve higher heat extraction compared to single-perforation fracturing (SPF). By using an improved sensitivity indicator, the injection rate is found to significantly affect the fracture network area, while the in-situ stress difference has the greatest impact on heat extraction.
