Oil migration in shale formations across multiple scales from nanometers to meters, a topic
without receiving sufficient attention, is of great significance to the accumulation and …

Hydrogen can be a renewable energy carrier and is suggested to store renewable energy
and mitigate carbon dioxide emissions. Subsurface storage of hydrogen in salt caverns …

Spontaneous coal combustion (SCC) seriously threatens the safety production of coal
mines. A neoteric irreversibly thermo-sensitive composite gel based on konjac glucomannan …

Underground porous media are complex multiphase systems, where the behavior at the
macro-scale is affected by physical phenomena occurring at the pore (micro)-scale. The …

Coupled pressure-driven (viscous) flow and spontaneous imbibition are the main regimes
during shale oil production. Revealing the unclear mechanisms of this coupled flow is a …

This study developed a shale hydration inhibitor using a citric acid-based deep eutectic
solvent (Cit-DES) and hexadecylammonium bromide (cetyltrimethylammonium bromide) to …

The carbonate reservoir plays a pivotal role in conventional oil and gas reservoirs. However,
due to limited knowledge of fluid flow characteristics in fractured-vuggy carbonate formations …

A relatively large number of pH-sensitive minerals (eg, calcite, dolomite, siderite) and redox-
sensitive compositions (eg, organic matter, siderite, pyrite, and chlorite) are present in gas …

Water-based working fluids are widely applied in the development of tight gas formations.
However, these fluids' flowback rate is generally low than 50%, resulting in a large amount …

This study utilized anthracite coal samples from Zhijin Block and applied NaClO as the
oxidant to investigate the effects of oxidation treatment on permeability enhancement and …
