20060211775 - Saponified fatty acids as breakers for viscoelastic surfactant-gelled fluids: Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities affected (increased or reduced, e.g. gels broken) by the indirect or direct action of a composition that contains at least one fatty acid that has been affected, modified or reacted with an alkali metal base, an alkali earth metal base,...

20060211776 - Compositions and use of mono-and polyenoic acids for breaking ves-gelled fluids: Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a composition that contains at least one unsaturated fatty acid, such as a monoenoic acid and/or polyenoic acid. The unsaturated fatty acid may be contained in an oil-soluble internal phase...

20060205827 - Method for controlling the stability or the droplets size of simple water-in-oil emulsions, and stabilized simple water-in-oil emulsions.: The invention concerns a process for controlling the stability or the droplets sized of simple water-in-oil emulsions, wherein a diblock or tri-block copolymer is used. A block is a hydrophilic block, the other block is a hydrophobic block. The invention concerns also a stabilized water-in-oil emulsion....
