Primary Examiner-Marvin A. Champion Assistant Examiner-Jack E. Ebel Att0rneyThomas H. Whaley [57] ABSTRACT 22 Claims, No Drawings 1 METHOD FORTHE IGNITION OF lN-S'I'FU COMBUSTION F OR" THE RECOVERY OF PETROLEUM BACKGROUND OF THE INVENTION This invention relates generally to a method of igniting and initiating an in situ combustionina subterra nean hydrocarbon-bearing formation.
In modern day production of hydrocarbons from-subterranean formations, it is common practice to apply secondary recovery techniques to recover additionalquantities of hydrocarbons. One of the more common secondary recovery techniques currently employed is that of insitu combustion." in this method of producing hydrocarbons, in situ combustion is initiated in the hydrocarbon-bearing,formation near a well bore penetrating the formation and acombustion front is established. Once the formation has been successfully ignited, a combustion-supporting gas, e.g., an oxygencontaining gas such as compressed air, is injected into the wellbore to support and drive the combustion front through the formation, thereby displacing. the hydrocarbons in the formation toward aproduction well from which they" are produced.
Successful ignition is generally dependent upon gencrating a" temperature sufficient to support and propagate the combustionfront. Amongthe'techniques-used for initiating the in situ combustion included in the prior art are various types of ignitors such as downhole heaters, electrical heatingxdevices'and combustibles introduced into the well bore. Results from the utilization of many of these techniques have beenless-than satisfactory, primarily due to" the fact that sufficiently high temperatures were not generated to ignite successfullythe formation and establish a combustion front.
SUMMARY OF THE lN-VEN'IION The invention herein disclosed provides an improved method of'generatingsufficiently high temperatures in a well bore adjacent a hydrocarbon-bearing formation to initiate an in situ combustiontherein. A high temperature is attained by the reaction of a solution of hydrogen peroxide containing water in amounts of from to percent by weight, which solution is contacted" in the well bore with a substance that reacts with the hydrogen peroxide to producean-exothermic reaction. As a result of the high temperature generated thereby within the formation adjacent the. well bore, the ignition temperature of the hydrocarbons therein is attained and in situ'combustion is'initiated.
DESCRIPTION OF THE PREFERRED EMBOPIMENT I A broad aspect of the invention comprises introducing into a well bore penetrating a-hydrocarbon-bearing formation a substance capable of reactingwith hydrogen peroxide whereby the temperature of the formation will be raised at least to the ignition temperature of the hydrocarbons contained therein, and thereafter introducing a solution ofhydrogen peroxide and water containing from 10 to 20 percent by weight of water. By the heat set free as a result of the reaction of the .hydrogen peroxide with the aforementioned substance, the temperature increases until reachingat least the ignition temperature of the hydrocarbons and oxygen which is formed as a result of the thermal decomposiposing the hydrogen peroxide include catalytically active substances and hydrogen peroxide oxidizing or reducing substances. Examples of catalytically active substances are substances with large surfaces, manganese dioxide, ferrous salts, catalases and platinum metals finely divided on an inert supporting material. These substances do not undergo substantial changes in the reaction with. hydrogen peroxide or its decomposition process. Examples of hydrogen peroxide oxidizing substances are the permanganates. Examples of hydrogenperoxide reducing substances are hydrazine, hydroxylamine and derivatives thereof. By the reaction of these latter substances withhydrogen peroxide, heat of reactionis set free contributing advantageously to an additional increase of thetemperature.
In a preferred embodiment the hydrogen peroxide and the reacting substance are contacted within the formation well bore adjacent the hydrocarbon-bearing formation, for example, by lowering the reacting substance via tubing in the well bore and pumping hydrogenperoxide containing water into the formation through the tubing. If the reacting substance is in solid form, it is-first broken into pieces and may be introduced in a perforated container. If the reacting substance is in liquid form, the container is designed as a closedvessel provided with outlet closing means. The container may be lowered either hangingon' a rope or by permitting it to falldown. If the substance contains a liquid decomposing agent, it may be provided with a striker by which the closing or bursting disk or the striker itself is crushed causing the decomposingagent to flow out the underground end of the tubing. Prior to pumping the hydrogen peroxide containing water down the tubing, the tubing may be flushed by an agent such as paraffin oil to inhibit the decomposition of the hydrogen peroxide prematurely.
In a particular embodiment of the method of the invention an internal pipe is run through the tubing to the underground of said tubing. The hydrogen peroxide containing water is pumped down either through the annulus or through the internal pipe, while a liquid decomposing agent, e.g., hydrazine, is pumped down through the annulus or through a second tubing. Because of the lesser pipe diameter it is economically justified to treat the internal wall of the internal pipe with decomposition inhibiting substances, e.g., paraffin, polyethylene or bitumen.
By pumping water down the combustion rate may be reduced or the combustion process stopped.
Use is made under particular circumstances which have to be established by pilot tests ofthe petroliferous layer to serve as the hydrogen peroxide decomposing agent, thereby saving the need' for charging the decom posing agent from outside.
The steam developing during the decomposition of the hydrogen peroxide has the advantageous effectof acting as an additional driving agent for the petroleum.
Once the formation has been successfully ignited, a combustion supporting gas, e.g., air, is utilized to drive the combustion front forward toward an adjacent production well from which recovery of hydrocarbons is realized. Alternatively, it may be found advantageous to discontinue injection of the combustion supporting gas and use a water flood to.drive the combustion front toward the production well.
