Well completion and related methods for enhanced recovery of heavy oil

摘要

A well completion for use in enhanced recovery of heavy oil includes a compressor for pressurizing natural gas captured from a heavy oil formation to a specified pressure while maintaining the pressurized gas at a specified temperature by controlling conduction from the pressurized gas of adiabatic heat produced in its pressurization. The pressurized and heated natural gas is then reintroduced to the heavy oil formation to enhance production therefrom.
