EFFICIENT SURFACE AND DOWNHOLE HEATING OF INJECTED CARBON DIOXIDE
A process for injection of CO2 in high-temperature reservoirs, where preheating of the injected stream is necessary. The process comprises producing hot water from a distant well, using the produced hot water in a surface heat exchanger for heating CO2. Alternatively, the produced hot water may be u...

| description | A process for injection of CO2 in high-temperature reservoirs, where preheating of the injected stream is necessary. The process comprises producing hot water from a distant well, using the produced hot water in a surface heat exchanger for heating CO2. Alternatively, the produced hot water may be used in a wellbore heat exchanger to heat the incoming CO2 as a counter-current heat exchanger. When the available CO2 is substantially cooler than the ambient, preheating via solar thermal is desirable prior to feeding to the heat exchanger. |
