Uniquely occurring carbonated geothermal waters are not well known in their origin-evolution process, geologic settings of deep ground water systems, and their flow behaviors in response to the unique physicochemical properties. Through deep-borehole data, and field samplings of various isotope and aqueous geochemistry data, we characterized these carbonated and generic geothermal waters, and analyzed water-rock reactions in relevant silicate rocks. Carbonated waters have high contents of HCO₃⁻ and dissolved CO₂, and enhance their leaching effect in such a way consequently leading to much higher major ion concentrations than non-carbonated thermal waters. According to δD and δ¹⁸O data, both carbonated waters and non-carbonated waters are of local meteoric origin and recharge from the hilly areas scattering throughout the study area at elevations ranging from 492 to 602 m (masl). The δ¹³C results confirm that the high DIC contents in carbonated waters have their deep sources of both mantle and carbonate rock thermal metamorphism genesis. Thermal reservoir temperatures are estimated for water samples, yielding a temperature range of 48.2 to 134.8 °C, based on chalcedony and quartz geothermometers. A 3500-m-deep borehole for carbonated water has revealed the relatively low geothermal gradient (2.35 °C/100 m) in the carbonated water convergence zone, which is related to the localized depression of the granitic-igneous basement within the study area. Relatively low-temperature environments have formed in localized basement depressions with thick cover of sedimentary rocks, and thus have provided excellent storage condition for deep-derived CO₂ rising along deep faults, forming carbonated waters when combined with groundwater systems. The deep crustal groundwater flow was further examined for the crustal thermo-structure, showing the heat flow and temperature distribution in each layer of the crust. The findings and insights could provide further understanding of deep ground water flow systems and deep groundwater circulations. The implications involve effective exploitations and utilizations for carbonated water and non-carbonated thermal water. This study is the first of the kind to study the deep ground water systems including carbonated waters and non-carbonated thermal waters in deep fault-basin systems, in terms of the deep sourcing, ground-water circulation, and thermal structure of the deep crust, and deep groundwater circulation in deep fault settings.</div></div>","PeriodicalId":55095,"journal":{"name":"Geothermics","volume":"131 ","pages":"Article 103390"},"PeriodicalIF":3.5,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geothermal energy potential exists in Pakistan; however, these resources have not yet been fully tapped because of a lack of research. The present study aims to utilize 2D seismic and well data to explore the geothermal potential of the Lower Indus Basin, specifically in the Sanghar Block, and the target was the Lower Goru Formation sandstone reservoir. The 2D seismic structural interpretation confirms that the area has normal faulting with the horst and graben structure, indicating extension tectonics. A seismic attributes analysis was performed on 2D seismic data, such as spectral decomposition, similarity variance, trace envelop, and instantaneous frequency. It also confirms the presence of geothermal anomalies, such as high frequency and reflectance, at the Lower Goru Formation. Two wells, Sono-2 and Sono-5, were utilised for studies in which heat production, formation temperature, average porosity, shale volume, and permeability were computed. Seismic inversion was performed to assess the impedance in the overall study block. Model-based seismic inversion analysis results indicated that 98 % and 92 % correlation were achieved at the Sono-2 and Sono-5 wells, respectively. Probabilistic Neural Network (PNN) techniques were employed for geothermal reservoir properties and interpolated in the seismic section to assess geothermal potential.

We compared the intrinsic attenuation distribution and the S-wave velocity structure of a region of the Javanese back-arc basin against its shear wave velocity structure. Our study highlights that Lusi’s plumbing system features two distinct fluid flow regimes, one across the shallow sedimentary units and one developing sub-vertically across the deeper domains of the basin. We show that ambient noise and intrinsic attenuation tomographies are complementary tools that should be performed routinely when studying geothermal systems. For decades, this region has been considered a hydrocarbon province as shown by the dozens of wells extracting hydrocarbons form the reservoirs. However, we instead highlight that such a basin is rich in geothermal resources. In particular, we argue that since the hydrocarbon extraction is declining and the energy transition is becoming imperative, the available hydrocarbon facilities should instead be repurposed for the extraction of geothermal resources. The high geothermal gradient, the steep topography of the nearby volcanic arc driving fluid flow and the well-studied subsurface, make this portion of the Kendeng basin an excellent geothermal site. Furthermore, the abundant geothermal resources at depth could be harnessed by re-purposing the dozens of wells drilled in the depleted oil and gas fields.

This paper proposes a method for detecting hidden geothermal resources by focusing on near-surface thermal anomalies.

Geothermal resources in the western areas were confirmed through drilling, which produced hot water at 50 °C and a flow rate of 40 L/h from an 800-meter deep basement reservoir. The slight thermal anomaly in the eastern area is likely due to the Urban Heat Island effect rather than deep heat.

Electromagnetic surveys indicate the presence of a large high conductivity anomaly towards the north of the caldera and very high resistivity where the deep wells were drilled, which is probably related to the intense silicification observed in the core samples from the deep wells.
