Methods of increasing oil production from a subterranean formation, method of hydraulic fracturing, and surface treatment compositions used therein

A method of increasing oil production from a siliceous or metal (M) oxide-containing subterranean formation penetrated by a well, the method comprising:

• (1) injecting into the well a surface treatment composition at an injection pressure wherein the surface treatment composition comprises:
• (a) a fluid comprising a hydrocarbon liquid, a supercritical fluid, and/or a liquefied gas, wherein the fluid (a) comprises CO2;
• and
• (b) a surface modifying component comprising:
• (i) an organometallic compound comprising tantalum, titanium, zirconium, lanthanum, hafnium, and/or tungsten, wherein the organometallic compound (i) is present in the surface treatment composition in an amount of 0.005 to 2.5 percent by weight, based on the total weight of the surface treatment composition;
• and
• (ii) an organosilane having halogen substituents, wherein the organosilane (ii) is present in the surface treatment composition in an amount of 0.005 to 25 percent by weight, based on the total weight of the surface treatment composition, wherein the organosilane (ii) comprises amine, carbonyl and/or sulfonate functional groups;
• (2) allowing one or more components of the surface treatment composition to chemically bond to a surface of the subterranean formation;
• and
• (3) removing oil from the well or from one or more production wells that are in fluid communication with the well.

A method of carbon sequestration within a siliceous or metal (M) oxide-containing subterranean formation penetrated by a well, the method comprising:

• (1) injecting into the well a carbon-containing surface treatment composition at an injection pressure wherein the carbon-containing surface treatment composition comprises:
• (a) a carbon dioxide-containing fluid comprising a carbon dioxide-containing hydrocarbon liquid, supercritical carbon dioxide, and/or a carbon dioxide-containing liquefied gas;
• and
• (b) a surface modifying component comprising:
• (i) an organometallic compound comprising tantalum, titanium, zirconium, lanthanum, hafnium, and/or tungsten, wherein the organometallic compound (i) is present in the surface treatment composition in an amount of 0.005 to 2.5 percent by weight, based on the total weight of the surface treatment composition;
• and
• (ii) an organosilane having halogen substituents, wherein the organosilane (ii) is present in the surface treatment composition in an amount of 0.005 to 25 percent by weight, based on the total weight of the surface treatment composition;
• and
• (2) allowing one or more components of the surface treatment composition to chemically bond to a surface of the subterranean formation.
