20110263466 - Method of simultaneously dissolving calcium carbonate, silica, and silicate minerals in subterranean formations: A method of dissolving minerals in subterranean formations is set forth. The method includes injecting a chelating solution into a subterranean formation. The chelating solution includes a thermally stable chelating agent and sufficient caustic to elevate the pH to 10-12.5. The chelating solution is capable of simultaneously dissolving silica, silicates,... Agent:
20110263467 - Process for producing mineral oil using surfactants based on a mixture of c32 guerbet-, c34 guerbet-, c36 guerbet-containing alkyl alkoxylates: The present invention relates to a process for mineral oil extraction by means of Winsor type III microemulsion flooding, in which an aqueous surfactant formulation comprising at least three ionic surfactants which are different with regard to the alkyl moiety (R1)(R2)—CH—CH2— and are of the general formula (R1)(R2)—CH—CH2—O—(D)n—(B)m—(A)l—XYa− a/b Mb+... Agent: Basf Se*10/20/2011 > 3 patent applications in 3 patent subcategories. categorized by USPTO classification
20110257050 - Dry blend fracturing fluid additives: A method and composition for crosslinking a polymer based fluid includes providing a dry blend of crosslinker and delay agent. The crosslinker and delay agent are mixed and granulated in a dry form prior to addition to the polymer fluid.... Agent:
20110257051 - Consolidating emulsions comprising convertible surfactant compositions and methods related thereto: Methods are provided that include a method comprising: providing an emulsified treatment fluid comprising an oleaginous phase, an aqueous phase, a consolidating agent, and an emulsifying agent that comprises at least one convertible surfactant described by a one of the disclosed formulae, and placing the subterranean treatment fluid in a... Agent:
20110257052 - Method for practicing microbial enhanced oil recovery using nitrogen containing fertilizers recovered from contaminated water for feeding microbes: A method of using nitrates, nitrites, or ammonium recovered from contaminated water for feeding microbes used in microbial enhanced oil recovery (MEOR). If required, the nitrogen waste removed from contaminated waters is treated to be converted as nitrates or nitrites. The nitrates and nitrites are mixed with microbes that are...

20110251111 - Foaming agent for subterranean formations treatment, and methods of use thereof: wherein R is a linear alkyl, branched alkyl, alkyl cycloaliphatic, or alkyl aryl group; O is an oxygen atom; Y is either a sulfur or phosphorus atom; m is 1 or more; n is a integer ranging from 1 to 3; p is a integer ranging from 1 to 4;... Agent:10/06/2011 > 3 patent applications in 3 patent subcategories. categorized by USPTO classification
20110245112 - Reconditioning and reuse of wellbore servicing fluids: A method of servicing a wellbore comprising preparing a wellbore servicing composition having a target water content, placing the wellbore servicing composition in the wellbore, recovering from the wellbore a recovered wellbore servicing fluid having a modified water content, wherein the modified water content is greater than the target water... Agent: Halliburton Energy Services, Inc.
20110245113 - Method of subterranean formation treatment: A method of treating a subterranean formation with a xanthan-viscosified cesium formate brine wherein the pH and/or another characteristic selected from density, xanthan loading, sodium formate loading, potassium formate loading and combinations thereof are modified to delay solid hydrogel formation and maintain pumpability. Also disclosed is a method of delaying... Agent: Schlumberger Technology Corporation
20110245114 - Well servicing fluid: A well servicing fluid formulated with components comprising a friction reducer having at least one polymer unit chosen from acrylamide groups, acrylate groups, sulfo groups, and maleic acid groups; and an anionic surfactant, a cationic surfactant and an aqueous base capable of forming a viscoelastic gel. Methods of making the... Agent:Previous industry: Superconductor technology: apparatus, material, process
Next industry: Solid anti-friction devices, materials therefor, lubricant or separant compositions for moving solid surfaces, and miscellaneous mineral oil compositions
