Single well vapor extraction process

摘要

A method of producing hydrocarbons from a subterranean formation comprising the steps of: forming a well having a horizontal section located between the midpoint and the bottom of the formation and having a raised end; and continuously injecting a fluid through said raised end to induce hydrocarbons to flow towards the horizontal section in response to gravity drainage while continuously producing hydrocarbons through the horizontal section of the well-bore, so that the injection of fluids occurs simultaneously with the production of hydrocarbons.
