Treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications.... http://www.freshpatents.com/Well-treatment-compositions-containing-nitrate-brines-and-method-of-using-same-dt20090813ptan20090203554.php Tue, 18 Aug 2009 22:47:54 -0700 Brine-based well treatment compositions containing alkali nitrate exhibit greater thermal stability when used in deep wells than substantially similar brine-based well treatment compositions which do not contain an alkali nitrate. The brine is thickened with a water-soluble crosslinkable polymer and crosslinking agent. The enhanced thermal stability of the well treatment... http://www.freshpatents.com/Use-of-relative-permeability-modifiers-in-treating-subterranean-formations-dt20090813ptan20090203555.php Tue, 18 Aug 2009 22:47:54 -0700 A method for treating a subterranean formation penetrated by a wellbore utilizes forming at least one of a treatment fluid A and a treatment fluid B. The treatment fluid A comprises an aqueous carrier fluid, a first relative permeability modifier (RPM) polymer, a water-soluble viscosifying polymer and a crosslinking agent... http://www.freshpatents.com/Gelled-hydrocarbons-for-oilfield-processes-phosphate-ester-compounds-useful-in-gellation-of-hydrocarbons-and-methods-for-production-and-use-thereof-dt20090813ptan20090203556.php Tue, 18 Aug 2009 22:47:54 -0700 Phosphate esters useful for gelling hydrocarbons in combination with a metal source are disclosed along with methods of preparation of the phosphate esters. Fouling in oil refinery towers has been attributed due to distillation of impurities present in phosphate esters used to gel hydrocarbons for oil well fracturing. The improved... http://www.freshpatents.com/Method-and-composition-for-enhanced-hydrocarbons-recovery-dt20090813ptan20090203557.php Tue, 18 Aug 2009 22:47:54 -0700 The present invention provides 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 composition comprises one or more internal olefin sulfonates having 17 or more carbon atoms, (b) adding water and/or brine... http://www.freshpatents.com/Method-and-composition-for-enhanced-hydrocarbons-recovery-dt20090813ptan20090203558.php Tue, 18 Aug 2009 22:47:54 -0700 A method of treating a hydrocarbon containing formation is described. The method includes (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein (i) when the salinity of the brine is from about 2 wt % to about 4 wt %, the composition...
