CO2 Flood: Field Operation: Reservoir Depth

Despite knowing the fact that

(a) start-up and field operating costs increase with reservoir depth;

(b) deeper wells resulting in higher drilling costs and enhanced operating costs to inject and pump out fluids;

(c) with reservoir temperature increasing with depth, resulting in a higher MMP, and in turn, requiring a larger volume of CO2 needed to achieve the same CO2 mobile pore volume slug; and

if deeper reservoirs are still preferred

with the hope that MMP would more likely to be reached,

does the effectiveness of an EOR project critically depend on pressure rather than temperature?
