Synergistic Impact of Integrated Water Control and Screen Pipe Technologies on Oil and Gas Production in Advanced Well Completions

The global expansion of oil and gas exploration into increasingly deep and geologically complex reservoirs has intensified technical challenges, particularly the detrimental effects of water intrusion and sand production. These issues severely curtail well longevity and recovery...

Sequential SolventExtraction Reveals Lithofacies-DependentPore Accessibility, Wettability, and Hydrocarbon Partitioning in Organic-RichLacustrine Shales

Abstract Understanding the reservoir characteristics of shale oil formations is an essential workflow in petroleum exploration and development because it supports petroleum-reserve evaluation and guides production activities. Few studies have examined the coupled effects of pore...

FNO-Speed: Accelerate Fourier Neural Operators Training for Solving PDEs

Deep learning for solving partial differential equations (PDEs) has become increasingly prominent. The Fourier Neural Operator (FNO) architecture has been proven to be an efficient and high-precision method that is widely used in scientific research. However, FNO incurs significa...

Temperature-DrivenInterconversion of Shale Oil

Abstract Understanding the occurrence state and thermal mobilization mechanism of shale oil is essential for improving recovery efficiency from nanoporous shale reservoirs. In this study, a series of thermal volatilization experiments (40–80 °C) combined with NMR (T2 and T1-T2) w...

Phase Behavior and Critical Properties of Hydrocarbons in Shale Illite Nanopores

Clay minerals are significant constituents of shale reservoirs, yet the confinement-induced phase behavior of hydrocarbons within clay nanopores has received comparatively less attention than in carbonaceous materials. In this study, Grand Canonical Monte Carlo (GCMC) simulations...

Artificial Intelligence for Hydraulic-Fracturing Decision Support: A Workflow-Oriented Critical Review

Hydraulic fracturing is a critical technology for unconventional oil and gas development, but its performance is strongly affected by geological heterogeneity, complex fracture propagation, operational uncertainty, and nonlinear interactions among engineering parameters. Artifici...
