This work aims to explore the use of stable graphene oxide (GO) dispersions for enhanced carbon capture and oil recovery. The objective of the study was to explore novel GO dispersions for effective carbon utilization. Initially, the GO particles were synthesized via the modified Hummers method and dispersed in a 1000 ppm PAM solution. These solutions (0.1 and 0.3 wt% GO) were observed visually and using a particle size analyzer in which they did not show any instability of agglomeration for 28 days. Given their superior stability, the GO dispersions were then used for CO 2  solvation in which the amount of CO 2  solvated in the solution (molality) was ascertained using the well-established pressure depletion method. Increasing temperature was found to reduce the CO 2  uptake while increasing pressure and GO concentration increased CO 2  uptake. The GO dispersions were also able to resist CO 2  escape from the system for over 200 h. Finally, the carbonated GO dispersions were used for EOR and were able to mobilize up to 61% of original oil in place (OOIP) from a sand-pack. The presented approach has potential for the development of a highly efficient CO 2 -based enhanced oil recovery method for sandstone reservoirs.
