“…CO 2 is mostly delivered to the field at a high pressure (>1200 psi) and density (5 lb. /gal) into injection wells within a designed pattern based on computer simulation to optimize areal sweep of the reservoir [13,14]. Miscibility of CO 2 with the oil is important as it causes the physical forces (interfacial tension) holding the two phases apart to disappear.…”

“…Significant volumes of oil are produced during CO 2 -EOR. For example, the Wasson field, a Denver unit CO 2 -EOR has produced more than 120 million incremental barrels of oil through 2008, with more than 2 billion barrels of OOIP and 40% of oil remaining after Waterflooding [14,15,19]. All types of oil reservoirs, either carbonates or sandstone could be suitable for CO 2 -EOR provided the MMP can be reached [13,14].…”

“…The produced CO 2 with oil is separated and re-injected back into the reservoir, ensuring an increase in trapped CO 2 instead of being released to the atmosphere. In addition, CO 2 -EOR provides a market and revenues for the captured CO 2 from anthropogenic (industrial and power plants) sources [14,15]. As the project matures, the volume of injected CO 2 diminishes, while recycled volumes increase.…”

“…As the project matures, the volume of injected CO 2 diminishes, while recycled volumes increase. This indicates that CO 2 is being stored in the formation through a capillary trapping mechanism [10,13,14]. Colorado [10].…”

“…In so doing, subsequent projects employ CO 2 molecules from captured emissions to supply large quantities of CO 2 for EOR processes in oil fields. Technological advancement in CO 2 -EOR applications, such as 3D seismic and geomodeling reduce the rise of failures and improves the flooding efficiency [10,[13][14][15].

Carbon Capture, Utilization and Sequestration

Carbon dioxide (CO 2) has been injected into oil reservoirs to maximize production for decades. On the other hand, emitted CO 2 from industrial processes is captured and stored in geological formations to mitigate greenhouse gas effects. As such, greater attention is drawn to the potential of utilizing the captured CO 2 in EOR processes. A significant portion of the injected CO 2 remains trapped due to capillary forces and through dissolution in residual liquids. In organic-rich shales, the presence of isolated kerogen nanopores add to the sequestration process due to the adsorptive nature of the surface and its preference to CO 2 over methane (CH 4), in addition to the sealing capacities of these formations. This work summarizes the latest findings of the literature with the purpose of defining further areas of investigation to fully capitalize on the potential of CO 2 sequestration and utilization in kerogen nanopores.
