Impact of pressure on tertiary-CO2 flooding in a fractured chalk reservoir

Comparing these results with our previous work at lower reservoir pressure shows the positive effect of pressure on increasing the efficiency of the tertiary-CF in recovering more oil from a matrix-fracture system. Also, the tuned capillary pressure and relative permeability during WF indicate an active imbibition drive and a strongly water-wet system. Our findings are an important step towards modeling the tertiary-CO2 flooding in an actual fracture-chalk system.
