Shale oil and gas primarily exist in nanoscale pore-fracture networks. Thus, it is essential to
clarify the flow behavior of hydrocarbon in confined nanopores. This paper summarizes …

In recent years CO 2 injection in shale has been investigated with aim to enhance shale gas
recovery (ESGR) and permanently sequester CO 2. This paper reviews the state of research …

Studying the CO2–CH4 displacement process is of great importance to understand the CO2-
enhanced shale gas recovery technology. However, most studies have focused on the gas …

Nuclear magnetic resonance (NMR) has been widely used to evaluate the pore size
distribution (PSD) properties of coals. However, the NMR signal itself only provides a …

Abstract Evaluation of free and adsorption gas in the in-situ reservoir is extremely significant
for the exploration and production of coalbed methane. The adsorbed gas content is …

The complex and multiscale nature of shale gas transport imposes new challenges to the
already well-developed techniques for conventional reservoirs, especially digital core …

Water fracturing is widely employed as a reservoir-stimulating technology for the recovery of
unconventional oil and gas. However, the process suffers from massive water consumption …

Interactions between injected CO2 and shale formation during the process of CO2
sequestration with enhancing shale gas recovery (CS-EGR) may alter the physical and …

To better evaluate the reservoir quality and optimize shale gas extraction, it is necessary to
quantitatively characterize pore structure in shale reservoirs using complementary methods …

Nuclear magnetic resonance (NMR) has been widely used in petrophysical characterization
of coals. For NMR experimental data analysis, transverse relaxation time (T 2) cutoff value is …
