The exploitation of oil from unconventional reservoirs remains a challenging engineering
project, and enhanced oil recovery by imbibition is a crucial approach to tackle this problem …

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 …

The breakthrough of shale oil in North America led to a worldwide energy revolution. Shale
reservoirs show multiscale properties and a large proportion of nanopores compared to …

Initial water saturation has a significant influence on spontaneous imbibition, and it impacts
the imbibition rate and imbibed liquid dynamic distribution among pore networks. At present …

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 …

Spontaneous imbibition is an important mechanism for develo** fossil hydrogen energy.
However, the research of imbibition micromechanisms and scaling methods in tight …

Shale is featured by nanometer pores and ultralow permeability. Enhancing shale oil
recovery after primary production is challenging as a result of the low injectivity of water …
