20110263465 - Use of vinyl phosphonic acid for producing biodegradable mixed polymers and the use thereof for exploring and extracting petroleum and natural gas: P

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*

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... Agent:
