21 Preparation of biliquid foam compositions US361058 1982-03-23 US4486333A 1984-12-04 Felix Sebba
A biliquid foam composition is prepared by agitating a hydrogen bonded liquid containing a soluble surfactant to produce a gas foam and intermittently adding to the gas foam a non-polar liquid which is immiscible with the hydrogen bonded liquid, the surfactant-containing hydrogen bonded liquid and non-polar liquid being selected to provide a spreading coefficient equal to or greater than zero. The resulting mixture is agitated after each addition so as to cause the non-polar liquid to initially spread on the foam surfaces and thereafter form non-coalescing globules of non-polar liquid dispersed in a continuous phase of the hydrogen bonded liquid and each encapsulated in a double surfaced surfactant-stabilized film of the hydrogen bonded liquid containing the soluble surfactant. The quantity of non-polar liquid added at each addition is such that the hydrogen bonded liquid remains the environment of any encapsulated globules of non-polar liquid formed, the total phase volume ratio (PVR) of the non-polar liquid to the hydrogen bonded liquid being up to about 50. The biliquid foams prepared in accordance with the invention have several noteworthy applications. For example, biliquid foams made of hydrocarbons and water are exceptionally good cleaning agents since they comprise both a finely dispersed hydrocarbon which can remove greases and water combined with detergent which can remove water soluble soils.

24 HIGH ENERGY EMULSIFIER EP82902328.0 1982-06-21 EP0089962A1 1983-10-05 PATTERSON, William P.; BAILEY, Ronald J.
Appareil et procédé d'émulsification de fluides. Le mélange de fluides peut se faire soit avant que les fluides n'entrent dans l'appareil (100), soit dans l'appareil. Une pression extrêmement basse est créée et maintenue dans une chambre de l'appareil en augmentant la vitesse de l'écoulement d'au moins un fluide en faisant passer l'écoulement d'un passage de plus grand diamètre (110) vers un passage de plus petit diamètre (106). Des vapeurs des fluides à émulsifier se mélangent dans le passage de basse pression, lequel peut être un tube venturi. Lorsque les vapeurs mélangées passent du passage de plus petit diamètre vers un second passage de sortie de plus grand diamètre (114), la décélération se traduit par une augmentation de pression qui provoque l'affaissement des vapeurs mélangées dans les produits émulsifiés. Une seule émulsification dans l'appareil produit des particules émulsifiées ayant des diamètres de l'ordre de 0,01 à 2 microns. L'appareil peut effectuer l'homogénéisation du lait, l'émulsification d'un combustible et de l'eau, l'émulsification de solutions avec des fluides immiscibles et la production d'autres émulsions régulières ou thixotropiques.
25 Additive for viscoelastic fluid US12015710 2008-01-17 US08093187B2 2012-01-10 Yiyan Chen; Jesse C. Lee
Composition and method for shortening the shear recovery time of cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a co-gelling agent selected from triblock oligomeric compounds having hydrophilic (for example polyether) and hydrophobic (for example alkyl) portions. The co-gelling agent also increases fluid viscosity and very low co-gelling agent concentration is needed. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.

28 High energy emulsifier US307319 1981-09-29 US4430251A 1984-02-07 William P. Patterson; Ronald J. Bailey
An apparatus and method for the emulsification of fluids. Mixing of the fluids may occur before the fluids enter the apparatus, or in the apparatus. Extremely low pressure is created and maintained in an apparatus chamber by accelerating the flow velocity of at least one fluid as flow occurs from a larger to a smaller diameter passageway. Vapors of the fluids to be emulsified mix in said low pressure passageway, which may be a venturi tube. When the mixed vapors flow from the smaller diameter passageway to a second larger diameter outlet passageway, deceleration results in a pressure increase which causes the mixed vapors to collapse into the emulsified products. A single emulsification in the apparatus produces emulsified particles with diameters in the range of 0.01 to 2 microns. The apparatus is capable of homogenizing milk, emulsifying fuel and water, emulsifying solutions with immiscible fluids, and producing other regular or thixotropic emulsions.

32 METAL-MEDIATED VISCOSITY REDUCTION OF FLUIDS GELLED WITH VISCOELASTIC SURFACTANTS PCT/US2010048582 2010-09-13 WO2011034807A3 2011-07-28 CREWS JAMES B
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 metal ion source and optionally at least one second source. An optional second source may be a chelating agent where at least one reducing agent source may be additionally optionally used. Another optional component with the metal ion source includes a second, different metal ion source. The breaking composition is believed to directly attack the VES itself, possibly by disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid, and/or possibly by changing the chemical structure of the VES to give two or more products.
