Rigorous characterizations of fluid contents, rock/fluid interactions, and pore-size
distributions are crucial in the development of unconventional resources. As a nonintrusive …

Understanding the heterogeneity of the nanoscale pore structure is critical for assessment of
hydrocarbon flow and storage in porous reservoirs. Multifractal theory is a powerful method …

After flowback, the residual fracturing fluid will reduce the gas seepage space and influence
natural gas production, which attracts widespread attention. In this study, the irreducible …

Organic matter (OM)-hosted pores are the most prevalent pores in organic-rich shale, in
which shale gas is generated and stored. Ascertaining the pore structure of OM and its …

Impacts of water molecules on subsurface shale gas adsorption is a challenging topic in the
assessment of shale gas resources and the selection of optimized exploitation plans. And …

Shale oil is the main field of unconventional hydrocarbon exploration and exploitation.
Additionally, deep (> 4500 m) petroleum exploration in sedimentary basins is a worldwide …

The evaluation of pore-throat structure is essential for the exploration and exploitation of
tight oil and gas reservoirs. In this study, various experiments such as casting thin section …

Rock fabric and its influence on residual oil distribution are key issues to the highly efficient
development of shale oil. This study targeted the rock fabric and residual oil distribution, and …

Pore–throat structure is a key factor that influences the storage and fluid flow capacity of tight
sandstone reservoirs. By performing petro-physical characteristic tests, scanning electron …

Assessment of movable fluid is a key topic in production of tight formations. Evaluation of the
movable fluid was usually conducted on tight sandstone formations while rarely on black …
