Patent ID: 7845406

Claim:
A method for interfacing with a Geopressured-Geothermal (GPGT) conversion system, wherein said GPGT system separates gas and concentrates GPGT brine via distillation, said method comprising the steps of: a. flowing a portion of the gas separated from the GPGT conversion system, and/or other-source gas, to fire a Brayton-cycle power plant for the generation of shaft power to drive a vapor compressor to compress a quantity of low-pressure steam from a GPGT distillation process to be used for Thermal Enhanced Oil Recovery (TEOR); b. combining the compressed steam from step 16.a with a portion of the distilled water from the GPGT conversion system; c. heating further the TEOR fluid of step 16.b with a quantity of rejected heat from the Brayton-cycle power plant; d. heating further the TEOR fluid of step 16.c with any remaining gas; and, e. injecting the TEOR fluid of step 16.d to a suitable reservoir to promote TEOR thus achieving a fluid conditioning system (FCS) TEOR Mode 4 , wherein the FCS TEOR Mode 4 comprises: a GPGT well; a surge tank, wherein the surge tank is disposed to receive a quantity of unprocessed brine from the GPGT well and to separate the gaseous and liquid phases of the brine; a pelton turbine, wherein the pelton turbine is disposed to receive a quantity of exit brine from the surge tank and to remove a quantity of gas from the brine; a pre-heater, wherein the pre-heater is disposed to receive a quantity of degassed brine from the pelton turbine and to elevate the temperature of the degassed brine; a multi-effect distillation system (MED), wherein the MED is disposed to receive a quantity of the brine from the pre-heater and to concentrate the brine to near saturation; a system condenser, wherein the system condenser is disposed to receive a quantity of low-pressure end-effect steam from the MED and to condense the quantity of end-effect steam through heat exchange; a spray evaporation pond (SEP), wherein the SEP is disposed to provide heat exchange to a quantity of cooling water supplied by a quantity of the Thermal Enhanced Oil Recovery (TEOR) return fluid; a Brayton cycle, wherein the Brayton cycle is disposed to receive the gas separated from the brine to power the cycle; a vapor compressor, wherein the vapor compressor is disposed to receive the remaining end-effect steam from the MED and to compress the steam for use in TEOR collocated oil; an oil/gas/water separator, wherein the separator is disposed to receive a quantity of TEOR return fluid and to separate the quantity of return fluid into a quantity of oil, gas and water; and a heat exchanger, wherein the heat exchanger is disposed to receive a quantity of heat rejected from the Brayton cycle and to produce additional steam for TEOR.
