Method and apparatus for a downhole gas generator
First Claim
1. A downhole steam generation apparatus for injecting a heated fluid mixture into a reservoir, comprising:
- an injection section including a housing, a plurality of injector elements disposed in the housing, and an injector plate coupled to the housing;
a combustion section including a body coupled to the housing and forming a combustion chamber, wherein the injector elements are in fluid communication with the combustion chamber; and
an evaporation section including a nozzle coupled to the body, wherein the nozzle is operable to inject fluid droplets into the combustion chamber.

Abstract
A downhole steam generation apparatus and method of use are provided. The apparatus may include an injection section, a combustion section, and an evaporation section. The injection section may include a housing, injector elements, and injector plate. The combustion section may include a liner having channels disposed therethrough. The evaporation section may include conduits in fluid communication with the channels and the combustion chamber, and a nozzle operable to inject a fluid from the channels to the combustion chamber in droplet form. A method of use may include supplying fuel, oxidant, and fluid to the apparatus; combusting fuel and oxidant in a chamber while flowing the fluid through a plurality of channels disposed through a liner, thereby heating the fluid and cooling the liner; and injecting droplets of the heated fluid into the chamber and evaporating the droplets by combustion of the fuel and the oxidant to produce steam.

16. A method for injecting a heated fluid mixture into a reservoir, comprising:
-
positioning an apparatus in an injection wellbore that is in communication with the reservoir, wherein the apparatus includes a liner having a chamber; supplying a fuel, an oxidant, and a fluid to the apparatus; combusting the fuel and the oxidant in the chamber while flowing the fluid through a plurality of channels disposed through the liner, thereby heating the fluid and cooling the liner; injecting droplets of the heated fluid into the chamber counter flow to injection of the fuel and oxidant into the chamber; and evaporating the droplets by combustion of the fuel and the oxidant to produce the heated fluid mixture. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
