US patent 8967274 reviving depleted oil fields

It will get %80 of the oil out in very efficient flow rate and very low cost, for every $100 million you spend you will get back $5 billions.

Plus it is breakthrough Self-Priming Pump.

Buy using this invention we can make an average water pump with impeller to form a Cooling system, compressor or self priming pump, It is low cost less malfunctions easy to repair, long life.

Current recovery factors for oil fields around the world typically range between 10% & 60%

PV=nRT shows within few months the oil reservoir will start producing oil by just spending 20 to 100 million dollars. But when the oil starts to flow from tens of wells of  the reservoir, we will get $100 million dollars every month for tens of years.


We will get our money back within a month. & for 50 years we will get millions every month. From dead abandoned reservoir


Abandoned or depleted oil fields can contain enormous amount of oil as semi-solid rock or thick oil sludge, hundreds of meters below the surface. To lift this type of oil from such wells, it must be converted it into a runny liquid by heating and then the pressure above the reservoir of oil must be increased to drive the oil to the surface. Heat can be provided by underground combustion. Oxygen (or air) can be pumped into the underground reservoir. If there is sufficient volatile combustible material in the reservoir supplying oxygen can be sufficient to start combustion and the resulting heat and pressure can drive oil to the surface. In some reservoirs the residual oil may not readily combust, and additional fuel must be supplied, at least until sufficient heat is generated to vaporize some hydrocarbon fuel.

FIG. 15 shows an exemplary embodiment using two pumps equipped with tanks and magic pipe switchers. One pump is used to pump oxygen using the methods given in Example 1 deep into an abandoned or depleted oil reservoir. A second pump is used to pump a gas or liquid capable of reacting with oxygen to make a combustion reaction. The combustion reaction, deep inside the oil well, can generate super-heated gas and a tremendous rise of pressure inside the oil well. The heat can melt the semi-solid oil and converts it into a lower viscosity liquid, and the massive pressure can push the oil up the oil well pipe.

Any combustible gas can be used. In some embodiments a gas or liquid such as a hydrocarbon gas is selected which has gaseous products of combustion (e.g., CO.sub.2) to help increase the pressure in the oil field.

Initially, the flow of oil to the surface may be small, but as pressure builds inside the oil well, the recovery rate can increase substantially; it is estimated that about 7-10 barrels of oil can be recovered for every barrel-equivalent used to fuel the underground combustion. The useful life and total extractable oil from old oil fields can be extended dramatically by these methods.

Pumping oxygen or air into an oil reservoir and then starting combustion is a very good method for extraction of oil from abandoned oil reservoir. However, in some embodiments, any available gas such as CO.sub.2 or N.sub.2 or a gas mixture can be used without initiating combustion to pressurize an oil reservoir and push oil to the surface through a well pipe.

In some embodiments, the reactants necessary for combustion are all pumped into the oil reservoir from the surface. Such reactants can be two or more gases, a mixture of one or more gases and one or more liquids, or a mixture comprising gases and/or liquids with powders. Any suitable mixture can be used that can be ignited in the reservoir to generate heat and pressure in the oil reservoir.

In an oil reservoir with a plurality of abandoned oil wells, some wells can be used to pump oxygen into the reservoir and other wells can be used to extract the oil. No new wells are required--only a few pumping systems.
