“…Soaking and solubility period of CO 2 saturated with the liquid phase, eventually, miscible and trap in the reservoir (Lee et al 2019;Pranesh et al 2018;Mosavat and Torabi 2014). Supercritical CO 2 ooding changes the rock geomechanical property and yield a high amount of storage (Zhang et al 2019b;Zhang et al 2017;Sander et al 2014;Zunsheng et al 2014). Therefore, hysteresis modelling was successfully applied to the Neyveli lignite rock during WAG injection and more than 50% of supercritical CO 2 retention has been achieved.…”

A laboratory based investigation has been conducted on permeability damage and CO2 storage or retention in the lignite core during alternative injection of brine and supercritical carbon dioxide. Moreover, anthracite and bituminous coal beds were focused by the scientific community for effective production and reservoir formation damage study. But, now-a-days, lignite based coal bed methane reservoirs have attracted attention for productive exploitation and formation collapse investigation. Hence, for this purpose, a single component injection two phase (Brine + Supercritical CO2) coreflood test analysis under alternative injections were performed to investigate the occurrence of lignite structural collapse, permeability damage, injectivity decline and CO2 retention as well. The experimental study reveals that, due to gravity segregation there is a high rate of fluid saturation in lignite core and also, moderate level of heat transfer coefficient was also noted. Also, lignite core structural collapse under the brine and supercritical CO2 injection at different velocities resulted in huge volume of coal and kaolinite fines concentration. Kaolinite and coal fines migration resulted in pressure change and permeability decline in lignite core. The suspensions produced were passed to microstructural analysis and it revealed that kaolinite fine particle tends to possess a leaflet geometrical structure, which obstructed the cleats and restricted the fluid flow. Subsequently, hysteresis modelling (Pranesh 2018) was applied to this problem to quantify the amount of CO2 retention in lignite core. Additionally, statistical model, multiple linear regression was applied to this problem to validate the experimental model, which showed good agreement.

“…This project is not only the Chinese project among the 21 large-scale CCUS projects in operation in the world, but also the largest CCUS-EOR project in Asia [16]. Waterflooding is widely applied to many oilfields in China, but the technology of CO 2 flooding can enhance oil recovery remarkably (about 10~15%), which is greatly beneficial for the oil industry [17]. At present, there are hundreds of pilot tests or commercial projects in the world that are implementing CO 2 injection for enhancing oil recovery.…”

Carbon dioxide flooding is a strategic replacement technology for greatly enhancing oil recovery in low-permeability oilfields, which includes social benefits resulting from carbon emission reduction and economic benefits owing to the improvement of oil recovery. Therefore, it is of great significance to develop and apply the technology of CO2 flooding and storage in the petroleum industry. In reservoir conditions, CO2 is usually under a supercritical state, presenting both low viscosity and high diffusivity of a gaseous state and high density of a liquid state. The special phase behavior of CO2 directly affects its extraction capacity, resulting in the change of miscible behavior between CO2 and crude oil. In this paper, the ultra-high-pressure–high-temperature pressure–volume–temperature (PVT) system was used to evaluate the phase characteristics of CO2 during the process of reservoir development. The phase behaviors of the CO2/CH4/N2 crude oil system were compared and analyzed. Moreover, the matching mechanism between supercritical CO2 characteristics and oil–gas system miscibility was investigated and defined. This work deepened the understanding of the phase characteristics of CO2 in the process of miscible flooding, providing both theoretical guidance for the application of CO2 injection on oilfields and the essential scientific basis for the implementation of CCUS-EOR technology.
