Abstract: The present invention is directed to N-alkyldiamide compounds responding to the following formula (I), wherein: R1 or R2 is selected from hydrogen or a linear, branched or cyclic, saturated or unsaturated, hydrocarbon chain having from 1 to 40 carbon atoms, with the proviso that one and only one of R1 or R2 is hydrogen, R is selected from cyclic or branched, saturated or unsaturated, hydrocarbon aliphatic chain having from 2 to 15 carbon atoms. The present invention also relates to the use of the com pounds of formula (I) as a gelling agent and to gel compositions comprising said compounds of formula (I).

Abstract: Methods of acidizing a subterranean formation penetrated by a wellbore that include the steps of (a) injecting into the wellbore at a pressure below subterranean formation fracturing pressure a treatment fluid having a first viscosity and including an aqueous acid and a gelling agent selected from the group consisting of Formulas I-XI and combinations thereof; (b) forming at least one void in the subterranean formation with the treatment fluid; and (c) allowing the treatment fluid to attain a second viscosity that is greater than the first viscosity.

Abstract: The invention concerns the solubilisation of surfactants suitable for enhanced oil recovery within an aqueous medium, by mixing said surfactants and the aqueous medium, carried out under ultrasound, advantageously to provide an over-concentrated solution that can be re-diluted with water available at the extraction site without impacting on the salinity of same. The invention also concerns the extraction fluids obtained according to this solubilisation technique and the use of same in EOR.

Abstract: The present invention relates to a new process for synthesizing an amido alkyl betaine starting from a linear alcohol having from 8 to 22 carbon atoms, to an amido alkyl betaine prepared by the process with increased viscosity in water, and also to use thereof as a viscoelastic surfactant in oil and gas applications and home personal care applications. The present invention also relates to a process for synthesizing an amido amine starting from a linear alcohol having from 8 to 22 carbon atoms, and to an amido amine prepared by the process.

Abstract: A polymer includes (a) one or more first monomeric units, each independently comprising at least one bicycloheptyl-polyether, bicycloheptenyl-polyether or branched (C5-C50)alkyl-polyether group per monomeric unit, wherein the bicycloheptyl-polyether or bicycloheptenyl-polyether group may optionally be substituted on one or more ring carbon atoms by one or two (C1-C6)alkyl groups per carbon atom, and (b) one or more second monomeric units, each independently comprising at least one pendant linear or branched (C5-C50)alkyl-polyether group per monomeric unit, provided that the first and second monomeric units cannot both comprise a branched (C5-C50)alkyl-polyether group and is useful as a component in liquid compositions, such as aqueous latex coating compositions, personal care compositions, home care compositions, and institutional or industrial care compositions.
