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...

Preparation andEvaluation of Biopolysaccharide-BasedTemperature-Resistant Drilling Fluid Additives

Abstract Xanthan gum (XG), valued for its environmental friendliness and multifunctionality, has been extensively utilized in drilling fluids. However, its inadequate thermal stability at elevated bottomhole temperatures encountered in deep drilling operations has constrained its...

Evolution of Coupling Coordination Between Artificial Intelligence and High-Quality Energy Development: Evidence from China

The coordinated development of artificial intelligence (AI) and high-quality energy development (HED) is essential for advancing digital transformation and energy transition. However, existing research primarily explores the unidirectional impact of AI on HED, neglecting their bi...

Silica-Inspired Aerogel Thermal Metamaterials with Gradient Porosity: High-Temperature-Induced Pore Sintering Evolution via Nanoindentation

Localized densification of nanoporous silica under combined mechanical compression and elevated temperature involves coupled pore collapse, skeletal rearrangement, and thermally activated sintering. Clarifying how local pre-compression regulates these processes is important for u...

Research on the Microscopic Residual Oil Activation Mechanism of Heavy Oil in Different Water Content Stages

This paper investigates the occurrence characteristics, mobilization behavior, and controlling mechanisms of microscopic remaining oil in heavy-oil systems at different water-cut stages by using a visual microfluidic platform. A series of displacement and pressure-ramping experim...

Diagenetic controls on reservoir quality and heterogeneity of eocene red-bed sandstones: a case study from the Shahejie Formation, southern Bohai Bay basin, China

The lower sub-member of the fourth member of the Eocene Shahejie Formation (LSm-ESF) in the southern Bohai Bay Basin hosts red-bed sandstones that are increasingly targeted as deep hydrocarbon reservoirs, yet the quantitative controls of diagenesis on their reservoir quality rema...
