20110021384 - Drilling fluid additive and methods of stabilizing kaolinite fines migration: A method of drilling is disclosed and includes pumping a wellbore fluid into a wellbore through an earth formation, wherein the wellbore fluid comprises a base fluid and a surface active agent capable of altering wettability of fines located in the earth formation, and allowing filtration of at least a... Agent: Osha Liang/mi

20110021385 - Secondary emulsifiers for inverted emulsion fluids and methods for making and using same: A new class of secondary emulsifying agents for use in inverted mud and other inverted system is disclosed and method for making and using same.... Agent: Robert W. Strozier, PLLC

20110021386 - Microemulsion to improve shale gas production by controlling water imbibition: The invention provides a method for treating tight gas sand and shale subterranean formations, the method comprising: forming a solvent-surfactant blend by combining a solvent, a surfactant and a co-surfactant; adding a diluent to the solvent-surfactant blend to form a micro emulsion; wherein the wettability of the formation altered from... Agent: Schlumberger Technology Corporation David Cate

20110021387 - Reversible gelling system and method using same during well treatments: An all-oil reversible gelling system includes a polymer, a crosslinker, a gel accelerator, and an oxidant, wherein temperature activates the crosslinker so as to cause the system to form a gel, and the oxidant subsequently decomposes the gel. This gel is designed to seal temporarily portions of oil-producing or water... Agent: Bachman & Lapointe, P.C.

20110021388 - Microemulsifiers and methods of making and using same: A method comprising contacting a zwitterionic surfactant, co-surfactant, and water to form a microemulsifier, and contacting the microemulsifier with an oleaginous fluid under low shear conditions to form a microemulsion. A method comprising introducing a first wellbore servicing fluid comprising at least one oleaginous fluid into a wellbore, wherein the... Agent: Craig W. Roddy Halliburton Energy Services

20110021389 - Method and composition for enhanced hydrocarbons recovery: A method of treating a hydrocarbon containing formation, comprising (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein the hydrocarbon recovery composition comprises a propoxylated composition which comprises (1) a glycerol sulfonate of a propoxylated primary alcohol having a branched aliphatic group...
