Summary: Varied concentrations of H2S have been discovered in the carbonate reservoir of the Puguang gas field in China, where thermochemical sulfate reduction (TSR) is considered the primary process for H2S generation. The study conducted reactive transport modeling to simulate TSR and H2S generation processes, indicating that mineralogical composition and gas saturation in the reservoir affect the efficiency and extent of TSR reactions. The modeling results were reliable, with predicted H2S and CO2 concentrations comparable to observed values after calibration.

Summary: Petrography, petrophysics, and geochemistry are used to study the dolomitization and reservoir quality of an Upper Cretaceous carbonate reservoir in Abu Dhabi, United Arab Emirates. The dolomitization in highstand systems tracts is attributed to tidal and evaporative pumping as well as seepage reflux during relative sea-level fall. Dolomitization in bioturbation sites is attributed to localized geochemical conditions. The porosity and permeability of the dolostones are strongly controlled by depositional textures and subsequent diagenesis, including dolomite cementation and dissolution. The study highlights the importance of dolomitization in controlling reservoir lithology and heterogeneity in carbonate successions.

Summary: Geothermal energy is considered environmentally friendly, but geothermal fluids often contain high CO2 content which can be mitigated by re-injecting and mineralizing the captured CO2 underground. A 3D reactive transport modeling study was conducted in a geothermal field in western Turkey to evaluate the geochemical interactions and mineralization process under different scenarios with varying injection rates. The results showed stable CO2-charged fluid mixtures and limited mineralization due to differences in mineral content and CO2 mass fraction between the injected fluid and the reservoir, as well as the impact of temperature, pH, and convective dispersive fluxes. Comparisons with the CarbFix project in Icelandic geothermal reservoirs also showed differences in the mineralization process.

Summary: This study investigates the impact of in-situ and migrated oil on diagenesis and reservoir quality of microporous intra-shelf basinal lime mudstones in Abu Dhabi. The results show that the presence of oil delays calcite cementation, resulting in higher porosity and permeability in the oil zone. Other factors, such as grain-size variations and calcite cementation, also play a role in the reservoir quality. A conceptual model is developed to understand the diagenetic pathways and improve exploration of tight hydrocarbon reservoirs.

Summary: This study investigates the geochemical system of the Rosebank field in the Faroe-Shetland Basin, focusing on the dissolution and precipitation effects at the basalt-sandstone interface. The results show that the dissolution and precipitation processes control the basalt dissolution rate, while diffusion has minimal impact on reservoir quality.

Summary: The present study focuses on the depositional facies, diagenetic processes, and sequence stratigraphy of shallow marine carbonates in the Samana Suk Formation, Kohat Basin, to understand its reservoir quality. The study reveals that the formation was deposited in peritidal, lagoonal, and carbonate shoal settings on a gentle homoclinal ramp. The formation experienced various diagenetic processes, and the petrographic analysis shows the evolution of porosity. The study suggests that the reservoir potential varies among different facies, with shoal facies having good potential, lagoonal facies having moderate potential, and peritidal facies having poor potential.

Summary: The Lower Jurassic reservoir in the Niudong area of the northern margin of Qaidam Basin is a typical low permeability sandstone reservoir. The reservoir quality is mainly influenced by diagenesis, with compaction and cementation causing porosity loss and dissolution increasing porosity. Structural features of the study area, like nose uplift structure and developed fractures, provide favorable conditions for reservoir space and migration channels, ultimately improving the reservoir permeability.
