As a promising method of carbon emission reduction, carbon capture, utilization and storage
(CCUS) is an important technology to achieve carbon neutrality. CO 2 geological storage is …

In this work, we developed and systematically evaluated a novel dual-network CO 2-
responsive preformed particle gel (DN-CRPPG) to address CO 2 channeling and leakage in …

CO2 foam injection has been shown to be effective under reservoir conditions for enhanced
oil recovery. However, its application requires a certain stability and surfactant absorbability …

Foam flooding can effectively suppress CO 2 channeling, improving oil recovery and CO 2
storage efficiency. However, elevated reservoir temperatures can considerably impair the …

As one of the most widely used technology to ameliorate the reservoir's heterogeneity,
polymer gels have been applied for more than 60 years. However, how to plug fractured …

Acrylamide-based polymer gels have been applied to control the preferential flow in the
subsurface for decades. However, some commonly used crosslinkers, such as Cr (III) and …

A novel CO 2-resistant dispersed particle gel (CR-DPG) for gas channeling control was
successfully prepared by shearing an organic–inorganic composite bulk gel. The basic …

The injection of CO 2 into oil reservoirs to enhance oil recovery (EOR) has become a widely
accepted and effective technical method, which, however, remains subject to the gas …

Polymer flooding is the most commonly used method to enhance oil recovery. Due to the
harsh stratum environment, it is particularly important to prepare polymer systems with high …

Since the higher cost of epoxy resin, its application in reservoir plugging at high temperature
and high salinity was seriously restricted. Herein, the expensive epoxy resin was used as …
