Claims

What is Claimed:

1. A process of stimulating hydrocarbon recovery comprising

(a) introducing a gas, a liquefied gas or vaporized liquified gas, into an underground formation containing hydrocarbons;

(b) permitting said gas to be absorbed by said hydrocarbons,

(c) withdrawing said hydrocarbons containing said gas, liquefied gas or vaporized liquified gas absorbed therein; and

wherein a pill of Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles is inserted into the underground formation containing hydrocarbons, before, during or after the introduction of the gas, liquefied gas or a vaporized liquified gas.

2. The process of Claim 1 wherein the injected gas, liquified gas or vaporized liquified gas and Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles may also include one or more injectants, selected from the group consisting of fresh water, KCl water, diverters and any other injectant currently used in oil field remediation as part of the treatment.

3. The process of Claim 1 wherein said pill of Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles is inserted into the underground formation containing hydrocarbons before the introduction of the gas, liquified gas or a vaporized liquified gas.

4. The process of Claim 1 wherein said pill of Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles is inserted into the underground formation containing hydrocarbons during the introduction of the gas, liquified gas or a vaporized liquified gas.

5. The process of Claim 1 wherein said pill of Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles is inserted into the underground formation containing hydrocarbons after the introduction of the gas, liquified gas or a vaporized liquified gas.

The process of Claim 1 wherein said gas is selected from the group consisting of carbon dioxide, nitrogen, natural gas, liquified natural gas, liquified carbon dioxide and/or mixtures thereof.

The process of Claim 1 wherein said gas is carbon dioxide.

The process of Claim 1 wherein said gas is nitrog

The process of Claim 1 wherein said gas is natural

The process of Claim 1 wherein said gas is liquified natural gas or liquified carbon dioxide.

11. The process of Claim 6 wherein said gas is a mixture of two or more gases selected from the group consisting of carbon dioxide, nitrogen, natural gas, liquified natural gas, liquified carbon dioxide and/or mixtures thereof.

The process of Claim 6 wherein said process is part of a huff and puff treatment process.

The process of Claim 12 wherein said process is a waterless fracturing process.

The process of Claim 13 wherein said process is a less water fracturing process.
