Enhanced oil recovery system for use with a geopressured-geothermal conversion system

A method for interfacing with a Geopressured-Geothermal (GPGT) conversion system, wherein said GPGT system separates a quantity of 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 an internal combustion reciprocating engine 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 49.a with a portion of the distilled water from the GPGT conversion system;
• c. heating the TEOR fluid of step 49.b further with a quantity of reject heat from said internal combustion reciprocating engine;
• d. heating further the TEOR fluid of step 49.c with a quantity of rejected heat from the internal combustion reciprocating engine;
• e. heating further the TEOR fluid of step 49.d with a quantity of remaining gas;
• and,
• f. injecting the TEOR fluid of step 49.e suitable reservoir to promote TEOR thus achieving a fluid conditioning system (FCS) TEOR Mode 4, wherein 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 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;
• an internal combustion reciprocating engine, wherein the reciprocating engine is disposed to receive the gas separated from the brine to power the engine;
• 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 reciprocating engine and to produce additional steam for TEOR.
