Performance of conversion plants for geopressured fluids has been predicted using realistic wellhead conditions and idealized thermodynamics. A method is developed for estimating the maximum output of a combined hydraulic-thermal recovery system. Performance of both flash and organic Rankine cycle schemes for thermal recovery is considered and the importance of hydraulic recovery is illustrated. Rankine cycle performance results for propane and isobutane are presented. Results are also given which illustrate the extreme importance of recovering dissolved methane due to its effect on both energy production and related economic viability.
