Prediction of gas production for shale matrix–fracture systems using deep operator network-ensembled physics-informed neural networks
Shale gas production forecasting remains challenging because flow is governed by strong nonlinearity, matrix–fracture interaction, and regime-dependent transport behaviour, while available production histories are often limited and erratic. Purely data-driven machine learning models can approximate…

Comparative study of the geological characteristics of sedimentary basins in Ghana: Implications for hydrocarbon generation potential
Ghana has four sedimentary basins, but attention has mostly been concentrated on the Tano Basin. This preference among potential investors is largely due to the fact that it has been extensively studied and also its established oil and gas reserves, which have facilitated the discovery and…

Fault sealing evolution in complex fault zones of the Houxia Basin, China
Fault sealing capacity is controlled by present-day geometry and clay content, with current research focusing on enhancing the accuracy of capacity estimates. The mechanisms for evaluating both present-day and paleo-sealing are consistent, where the current sealing capacity representing the final…

A rock physics model-based approach to delineate deep and tight sand reservoir heterogeneity in the Bohai Bay Basin, China
Delineating sweet spots is critical for the exploration and production of oil and gas in deep and tight sand reservoirs. The lack of advanced and reliable methods makes this a challenge for geologists and geophysicists. This study introduces, for the first time, an integrated workflow that combines…

A reservoir rock wettability modifier for ultra-high temperature and high salinity environment
During drilling process, the water phase in drilling fluids infiltrates rock fractures through capillary action. The surface wettability of dolomite is governed by multiple factors, resulting in an unstable wetting state. Studies have shown that altering the surface wettability of reservoir rocks…

Unconventional rare earth element archives in the energy transition era: The Cenozoic organic sediments from west coast of southern India
Organic-rich sediments represent vital components of Earth's geochemical cycles, acting both as potential hydrocarbon and coal reservoirs and as unconventional archives for critical metals such as rare earth elements (REEs). With the growing emphasis on clean energy technologies, the Cenozoic…

Assessment of carbon dioxide storage in the Gulf of Gabes, Tunisia: Analytical and numerical modeling
Significant hydrocarbon accumulations in the offshore Gulf of Gabes, Tunisia, remain largely undeveloped due to elevated concentrations of carbon dioxide (CO2), nitrogen (N2), and hydrogen sulfide (H2S), which compromise commercial viability and have delayed field development. Addressing these…

Multi-source and multi-attribute collaborative fracture network modeling of a sandstone reservoir in Ordos Basin
The effective channeling of fluid flow by fractures is a liability for enhanced oil recovery (EOR) methods like CO2 flooding or CO2 storage. Developing a distributed fracture model to understand the heterogeneity of the fracture network is essential in characterizing tight and low-permeability…

Carbon dioxide plumes, pressure space and legacy well risk for Southern North Sea CO2 storage projects
Unsecured legacy wells pose significant risks to carbon capture and storage (CCS) as they present potential leakage pathways for stored CO2 to return to the atmosphere. In the UK, legacy wells must be assessed for a carbon storage permit to be granted and high-risk wells require costly remediation…
