Recovery process for improved combustion in situ using a single horizontal well to make the Oil and the combustion gas to surface

摘要

This procedure provides at least one vertical Production well which has a substantially vertical part which extends downward to the Interior part of the deposit and a horizontal Base that extends horizontally Outward of it, being the part of horizontal Base Comp Letada relatively low in the deposit.At least one injection Well oxidizing gas vertical placed above and in Spaced relationship with the horizontal well is placed laterally along a horizontal Borehole.At least one injection Well vertical oxidizing gas, placed above and in Spaced relationship with the horizontal well is placed laterally along a horizontal Borehole approximately in the Middle section of the same.Oxidizing gas is injected in it and makes the combustion fronts towards outside of the injection well in mutually opposite directions along a horizontal Borehole.Preferably, provides a Plurality of injection Wells along the direction of the horizontal well and injecting an oxidizing gas in each one, and makes the combustion fronts towards outside and in opposite directions to each other, and makes the Oil drains down to L inside the horizontal WellOil with hot combustion gases are pushed out to the surface
