Evaluation of the Effectiveness of CO₂ Nanobubbles as an Enhanced Oil Recovery Method on Low Permeability Artificial Core

Background: Low-permeability reservoirs, characterized by limited pore connectivity and dominance of capillary forces, present significant challenges to conventional Enhanced Oil Recovery (EOR) methods. Water flooding often fails to mobilize residual oil in such reservoirs, which typically results in low recovery factors. Objective: This study aims to evaluate the effectiveness of the Enhanced Oil Recovery (EOR) method based on CO₂ nanobubbles in low-permeability artificial cores with matrix-sup
