Design a cycle to extract power from a geothermal well. The well is 14,000' deep and the water flow rate is at 45,000 Bbl/day. The downhole temperature and pressure are 325 F and 8000 psig, respectively. The reservoir brine is also saturated with dissolved natural gas. The brine may be re-injected into a reservoir that is 5000' deep. Assume hydrostatic pressure gradient, and an overpressure of 600 psi to inject into this reservoir. If any CO2 is produced in the cycle, it needs to be purified and sequestered. Please include an option for providing a clean CO2 stream at 1800 psig for injection into a subsurface reservoir.Design a cycle to extract power from a geothermal well.
