Abstract This study examines the co-application of CO2 huff-n-puff (HnP) technology for enhanced oil recovery (EOR) and sequestration in Vaca Muerta shale rocks. The rock samples undergo a primary production stage to establish depleted sample before conducting HnP storage experiments. is performed using associated produced hydrocarbon gas under representative reservoir conditions. objective identify key oil-recovery mechanisms during quantify capacity matrix after both stages. conducted at 5,000 psig with soaking time 16 hours, while experiment slightly lower pressure 4,420 an extended duration 420 hours maximize diffusion into matrix. findings reveal that CO₂ HnP, despite its shorter interval, enhances incremental from matrix, though significantly higher. Solution-gas drive followed by vaporization are identified as dominant achieves 48% greater compared experiment, primarily due period reduced place. core estimated 96.1% pore volume 65.2% test, where follows soaking.

Aiming at the challenges of rapid heat dissipation, limited swept efficiency, and a water cut increase in steam huff puff development heavy oil reservoirs, an alternating CO2/viscosity reducer method for IOR was proposed. In this work, effect CO2 on physical properties evaluated, optimal concentration viscosity synergistic interaction between determined. Next, novel simulation experiments by three sandpack models different sizes series were analyzed. Then, difference pure steam-alternating compared. Finally, storage rate obtained based principle conservation matter. The results show that concentration, 0.8 wt%, can achieve 98.5% reduction after combining CO2. reached about 45 cm 80 °C fifth cycle due to effects. significantly reduces during cold production, with ultimate 15.89% higher than puff. alleviates blockages, decreases enhances elastic repulsion energy. highest 76.8% occurs initial stage, declining 15.2% sixth cycle, indicating carbon sequestration potential. These findings suggest improves reservoir provides theoretical guidance optimizing processes.
