CONCLUSIONS
The preliminary study of the OCDOPUS concept have shown that it is a promising concept and merits further studies. With a temperature at the turbine inlet of 1050°C, a pressure range of 7 to 100 bars, and a turbine efficiency of 85%, the efficiency becomes about 35%, and no exhaust gases are released from the plant. If the prediction of 10:1 oil-recovery to CO2-injection ratio is valid, daily extraction of 1000 tons of crude oil is possible; if the ratio is only 0.5:1 extraction becomes 50 tons. The daily fuel consumption (0.538 kg/s) of the I0 MW plant is just 50 tons. Tnerefore, a ratio of 0.5: I is admissible when gaseous fuel is used and prohibitively low in case of crude oil combustion.
