Geological CO 2 sequestration in deep saline aquifers has been extendedly investigated to
reach the goal of carbon neutral as large amount of CO 2 can be reduced in a short time …

The largest Precambrian gasfield in China has been found in the central Sichuan Basin. It
has been assumed as an Ediacaran (Sinian) mound–shoal, microfacies-controlled, dolomite …

Numerical reservoir simulation of CO 2 storage in geological formations is computationally
expensive due to the complex, and often coupled, multiphase flow phenomena, and the …

Evaluating irreducible water saturation is crucial for estimating reservoir capacity and
develo** effective extraction strategies. Traditional methods for predicting irreducible …

The micropore structure of tight sandstone affects the efficiency of CO2 displacement of
crude oil. As the pressure changes, the oil displacement efficiency (E d) in segments with …

CO 2 huff-n-puff has been accepted as an effective technique to improve oil recovery in tight
oil reservoirs. Even though CO 2 EOR mechanisms were extensively investigated from …

It is generally believed that conventional hydrocarbon accumulates in sandstone traps after
migrating at a certain distance. Unconventional hydrocarbon only migrates at a short …

Quantification of methane content in shales is a critical parameter for estimation of their
potential gas production capacity. Traditional gravimetric methods for estimation of this …

Carbonate fractured vuggy reservoir in Tahe oilfield belongs to fractured vuggy reservoir
with strong heterogeneity. After a period of production, the elastic energy of the cave …

During the gas production process, the evaporation of formation water leads to an increase
in the water content of the gas and increases the salinity of the remaining formation water …
