Furthermore, co- and counter-diffusion processes are simulated to investigate CO 2 /CH 4 flux from and CO 2 injection into organic-rich shale and coal samples, representing moderate and high adsorption capacity...

... Abstract Smart Water (SW) can be defined as brine that has been chemically adjusted/optimized in terms of salinity and ionic composition or carbonation (CO 2 enrichment). The aim is to create a brine with an optimum chemical & ionic composition such that it changes the equilibrium...

... Abstract: The tight reservoir exhibits pronounced heterogeneity and possesses complex physical properties, thereby constraining crude oil exploitation. Water and CO 2 injection for enhanced oil recovery encounter challenges related to low sweep efficiency and viscous fingering, resulting...

... the mobility of heavy components, leading to their confinement. Consequently, heavy components within nanopores are difficult to extract during primary production processes. During the CO 2 injection period, the injected CO 2 induces a significant alteration in fluid composition within both macropores...

...% for the conventional waterflooding. During an ECWI process, a voltage of 10 V achieves the highest oil recovery, but that of 15 V has the best water injectivity and CO 2 storage capacity. It is found that the underlying recovery mechanisms result from both electroosmosis and enhancement of carbonized water-rock...

... Abstract Foam injection into naturally fractured reservoirs unequivocally has superior merits over pure gas injection. In this study, we present a novel foam generation strategy that incorporates the co-injection of surfactant and supercritical CO 2 with huff-n-puff technique for the efficient...

... Summary CO 2 flooding is emerging as a pivotal technique extensively utilized for carbon capture, utilization, and storage (CCUS) strategies. Acid stimulation is one common technique widely employed to improve well-formation connectivity by creating wormholes. This work is motivated...

The field underwent a first phase of GAGD from 1992 through 2000 restoring the oil-water contact down to the discovery depth of +1050 feet above sea level (ASL). Several steps were taken to quantify the transition zone target...
