“…Building upon this, the study of the composition, temperature-pressure conditions, fluid environments, and origins of fluids in calcite veins can elucidate fluid activity in the overlapping basin (Cao et al, 2010;Nomura et al, 2014;Jia et al, 2022;Rddad et al, 2022;Wei et al, 2023). It provides evidence for the migration of fluids within source rocks and reservoirs and, to some extent, indicates the geological fluid activity patterns and the influence of structural activity on fluid movement (Yu et al, 2017;Jaya et al, 2021;Zhu et al, 2022;Fornero et al, 2023). The Frontiers in Earth Science 03 frontiersin.org fluid inclusions in calcite veins preserve information about temperature, pressure, fluid type, and composition during mineralization, making them a crucial source of information for understanding the timing, temperature, pressure, and processes of oil and gas accumulation (Wang et al, 2020;Ping et al, 2023;Song et al, 2023;Zhou et al, 2023) This study focuses on the northern thrust fault zone of the Fuman Oilfield, utilizing analyses such as petrographic examination of calcite vein rock phases, fluorescence spectroscopy of oil inclusions, micro-area trace element analysis, Sr isotope analysis, micro-thermometry, and U-Pb isotope dating.…”

Marine deep Ordovician reservoirs are significantly controlled by strike-slip fault zones, which govern reservoir fluid evolution during various activity periods. Such fluid evolution elucidates the process underpinning ultra-deep oil and gas accumulation and delineates the pivotal role of strike-slip fault zones in hydrocarbon aggregation. This method can improve the understanding of the mechanism of hydrocarbon accumulation in deep to ultradeep carbonate rocks. The findings indicate that the Ordovician reservoirs in the northern thrust fault zone of the Fuman Oilfield predominantly exhibit two stages of calcite vein formation. The distribution patterns of rare earth elements and Sr isotope characteristics suggest that both stages of vein formation were sourced from Middle to Lower Ordovician marine strata, with no evidence of oxidizing fluid infiltration. This indicates that late-stage oil and gas charging in deep-ultradeep formations has good sealing properties. In these calcite veins, early-, middle-, and late-stage fluid inclusions were primarily entrapped. By examining the development of primary oil inclusions and combining the U‒Pb isotope data of host minerals, this study confirms the occurrence of three stages of oil and gas charging in the deep Ordovician strata of the northern thrust fault zone in the Fuman Oilfield. These stages correspond to approximately 459 ± 7.2 Ma (mid-Caledonian), 348 ± 18 Ma (early Permian), and 268 Ma (late Permian). The key accumulation period of oil and gas reservoirs in the study area is the middle and late Caledonian, and there is a good correspondence between oil and gas charging and fault activity.

“…Fractures, faults, or other geological features provide a conduit for the heated water to ascend toward the surface. These pathways may be created by tectonic activity or the natural fracturing of rocks [8,9]. As the pressurized hot water reaches the surface, it emerges through openings known as hot springs.…”

Numerous present-day hot springs in the Sulawesi region are divided into two, generally associated with non-volcanic and tectonics geothermal systems, only a small number are associated with active volcanoes, but most do not yet have data to support their utilization.Here we have conducted research at Makula Hot Springs South Sulawesi, the method used is combined geochemical analysis with an estimation of subsurface temperature by using the geothermometer at three sites at Makula Hot Springs. The percentage values of HCO³ˉ, Clˉ, and SO₄²ˉ ion content in hot water samples were analyzed, indicating that the hot springs area was included in the chloride water type. While the results of the estimation of subsurface temperature by using the geothermometer Na -K from the three sites each show the following temperatures: Site I is 124.69℃, Site II is 122.65℃, and Site III is 114.75℃. All sites result in estimations suggested including the low enthalpy which has a temperature limit of <125℃. Furthermore, using the geothermometer Na -K -Mg is known, and the hot springs in the area are included in the partial equilibrium. Geothermal energy in the study area is used for public swimming baths, the development of a tourist attraction, and potentially for a power plant. However, it is still necessary to investigate the geothermal characteristics to maximize the utilization of the hot springs in this area.
