Underground hydrogen storage (UHS) is a promising technology with which large quantities
of H 2 can potentially be stored in the subsurface safely, economically and efficiently. As …

Small-angle scattering (SAS) is a technique that is able to probe the structural organization
of matter and quantify its response to changes in external conditions. X-ray and neutron …

The complicated flow behaviors of multiphase fluids in shale reservoirs are significantly
influenced by fluid-fluid and fluid-rock interactions due to the non-negligible intermolecular …

Different from the conventional oil reservoirs, the primary storage space of shale is
micro/nano pore networks. Moreover, the multiscale and multi-minerals characteristics of …

Tight sandstone reservoirs typically contain a wide pore throat sizes ranging from the nano-
scale to micro-scale, and have complex pore geometry and pore throat structure …

Abstract Scanning Electron Microscopy (SEM) and Atomic Force Microscope (AFM), two
easily acquired and widely applied image acquisition and analysis methods, have rarely …

Carbon dioxide (CO2)-enhanced coalbed methane recovery (CO2-ECBM) is a critical way to
increase methane production and reduce greenhouse gas (CO2 and CH4) emissions. As …

In this study, to clarify the role of water during thermal maturation on organic porosity
evolution, pore structure characteristics of the Qingshankou shale (type I kerogen) were …

Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and
gas fields and geothermal systems, and the extent and connectivity of the pore structure …

This paper reviews the significance of solid bitumen with emphasis on source-rock
reservoirs. We discuss difficulties and discrepancies with terminology, especially those …
