Special Issue Information

Dear Colleagues,

With global petroleum exploration being conducted in deep water, ultra-deep and super-complex parts of basins and the emergence of shale oil and gas, advances in petroleum exploration and application have been marked by significant technological and methodological innovations aimed at improving the efficiency, accuracy, and environmental sustainability of the industry. These advances highlight the dynamic nature of the petroleum industry and its ongoing efforts to adapt to changing energy demands and environmental challenges. The integration of cutting-edge technologies and sustainable practices is crucial for the industry's future success and its role in the global energy landscape. This Special Issue will cover, but not be limited to, the following theoretical and technological advances in petroleum exploration and development: (1) Earth System Science and/or Deep-Time Digital Earth (DDE)-based basin evolution with a particular focus on the coupling of deep mantle/crustal processes and sedimentary basin evolution, (2) deep-learning and big data in reservoir modeling, (3) innovative unconventional resource development, (4) novel reservoir simulation and modeling, (5) carbon capture, utilization, and storage (CCUS), and (6) energy transition and integration, with a particular focus on integrating renewable energy sources and exploring the role of hydrogen in the future energy mix.

Hydrocarbon-Bearing Hydrothermal Fluid Migration Adjacent to the Top of the Overpressure Zone in the Qiongdongnan Basin, South China Sea

The Qiongdongnan Basin constitutes a sedimentary basin characterized by elevated temperatures, significant overpressures, and abundant hydrocarbons. Investigations within this basin have identified hydrothermal fluid movements linked to overpressure conditions, comprising two vertically separated overpressured intervals. The shallow overpressure compartment is principally caused by a combination of undercompaction and clay diagenesis. In contrast, the deeper high-pressure compartment results from hydrocarbon gas generation. Numerical pressure modeling indicates late-stage (post-5 Ma) development of significant overpressure within the deep compartment. It is proposed that accelerated subsidence in the Pliocene-Quaternary initiated substantial gas generation, thereby promoting the formation of the deep overpressured system. Multiple organic maturation parameters, combined with fluid inclusion microthermometry, reveal a thermal anomaly adjacent to the upper boundary of the deep overpressured zone. This anomaly indicates vertical transport of hydrothermal fluids ascending from the underlying high-pressure zone. Laser Raman spectroscopy confirms the presence of both hydrocarbons and carbon dioxide within these migrating fluids. Integration of fluid inclusion thermometry with burial history modeling constrains the timing of hydrocarbon-carrying fluid charge to the interval from 4.2 Ma onward, synchronous with modeled peak gas generation and a phase of pronounced overpressure buildup. We propose that upon exceeding the fracture gradient threshold, fluid pressure triggered upward migration of deeply sourced, hydrocarbon-enriched fluids through hydrofracturing pathways. This process led to localized dissolution and fracturing near the top of the deep overpressured system, while simultaneously facilitating significant hydrocarbon accumulation and forming preferential accumulation zones. These findings provide critical insights into petroleum exploration in overpressured sedimentary basins. Full article

To increase the reliability of three-dimensional (3D) geological models in areas characterized by sparse well data and poor seismic quality, a sedimentary dynamics simulation was conducted on the J7 tidal delta sedimentary reservoir in the Y gas field, which is located in the West Siberian Basin. A 3D sedimentary model of the study area was developed by defining parameters such as bottom topography, water level, tidal range, river discharge, and wave amplitude. By integrating the reservoir characteristics, the sedimentary dynamics simulation results were transformed into a three-dimensional training template for multipoint geostatistical modeling. Simultaneously, the channel and bar parameters derived from the sedimentary dynamics simulation served as variable inputs for attribute modeling. Combined with well data, a 3D geological model of the reservoir was constructed and subsequently validated using verification wells. The results demonstrate that the reliability of reservoir lithology modeling—when constrained by three-dimensional training templates generated through sedimentary dynamics simulation—is significantly higher than that achieved using sequential Indicator simulation. Three-dimensional modeling of tidal delta reservoirs, employing coupled sedimentary dynamics simulations and multipoint geostatistical methods, can effectively enhance the reliability of reservoir geological models in areas with sparse well data, thereby providing a robust foundation for subsequent well deployment and development.
