Abstract
An in situ combustion process entailing the simultaneous production of liquids and combustion gases that combines fluid drive, gravity phase segregation and gravity drainage to produce hydrocarbons from a subterranean oil-bearing formation, comprising initially injecting gas, steam or a fluid through a horizontal well placed high in the formation, and initially producing hydrocarbons through a lower, parallel horizontal well. Thereafter, in accordance with the method, production from the lower well is ceased, and a gas, liquid, or steam injected into such lower well, and an adjacent parallel well likewise low in the reservoir is used to produce the oil. Significant portions of a reservoir may thereby be exploited by continually drilling lower adjacent horizontal wells in a direction along the reservoir and converting penultimate lower production wells into injection wells and thereby driving hydrocarbons to an adjacent parallel production well for recovery to surface. The process may further employ in-situ combustion.
