Mixing of injected gas and reservoir oil will change the initial saturation pressure, affect the deliverability of the oil.

The exergy analysis of an intercooled reheat steam injected gas turbine cycle has shown that such a cycle has a significantly higher exergy efficiency as compared with a simple STIG cycle.

But instead of coating the carbon cylinders with fuel, a liquid fuel could be stored in the car's gas tank and get injected onto the carbon nanotube battery when needed.
