Abstract Carbon Capture and Storage (CCS) has been widely recognized as an effective
strategy that may significantly contribute to achieving the net zero emission target by 2050 …

Supercritical fluids find use in various areas in oil and gas production operations due to their
unique properties. Supercritical CO 2 (sc-CO 2) with its reduced viscosity, increased …

Global shale oil is abundant in geological reserves, but there are widespread problems of
difficult exploitation and unsatisfactory oil recovery. CO 2 injection in shale reservoirs can …

The development of hydraulic fracturing and horizontal drilling techniques has promoted the
exploitation of shale gas resources. However, using water has several potential drawbacks …

CO 2 geo-sequestration is a promising technology to permanently store CO 2 in geological
formations to control the atmospheric carbon footprint. In addition, CO 2 is frequently utilized …

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 …

Due to the complexity of sedimentary rocks, especially the fine-grained and highly-
heterogeneous nature of some argillaceous caprocks in the subsurface, it is challenging to …

To better understand and implement the CO 2 sequestration project, it is of significance to
investigate the interaction of shales with CO 2 and its potential effects on the pore …

A significant amount of carbon dioxide (CO2) is being released into the atmosphere as a
result of the acceleration of industrialization and increased energy consumption, which are …

Shale is a source rock for hydrocarbon recovery that can be stimulated by CO 2-based
fluids, as well as a caprock for CO 2 geological sequestration due to its extremely low …
