Conventional enhanced oil recovery (EOR) approaches are inefficient in unconventional
reservoirs. This paper provides a novel approach to enhance oil recovery from …

Focusing on vertical multi-layer superimposition of unconventional natural gas reservoirs in
coal-bearing strata, research on the co-production of tight gas and coalbed methane from a …

In this study, an in-house reduced black oil simulation model is used to investigate cyclic
produced gas rejection in Eagle Ford shale formation. Molecular diffusion may play a crucial …

Harsh subsurface environments limit the robust workability of on-site instrumentation to be
leveraged to track the Earth's dynamics. Distributed fiber-optic sensing (DFOS) enables the …

As a result of deep burial depth, small pore throat, poor connectivity between pores, different
clay mineral contents in reservoirs, and strong reservoir sensitivity, injection wells often have …

The accurate forecasting of oil recovery factors is crucial for the effective management and
optimization of oil production processes. This study explores the application of machine …

Confined phase behavior plays a critical role in predicting production from shale reservoirs.
In this work, a pseudo-potential lattice Boltzmann method is applied to directly model the …

Field data indicates that oil production decline quickly and the oil recovery factor is low due
to low permeability and insufficient energy in the tight oil reservoirs. Enhanced oil recovery …

Taking the low-permeability reservoir of complex sandy conglomerate reservoir of Kongdian
Formation in Bozhong structure as the research goal, the comprehensive discrimination …

Extremely small pore size, low porosity, and ultra-low permeability are among the
characteristics of shale rocks. In tight shale reservoirs, the nano-confinement effects that …
