The heat produced in the gas to liquid conversion installation is used to produce energy () to pressurize () the nitrogen in the nitrogen rich stream () to produce a pressurized nitrogen rich stream (). The pressurized nitrogen rich stream () is passed into a natural oil reservoir () to enhance the recovery of oil () from the reservoir.
