Abstract: The invention provides a synergistic surfactant composition comprising: (a) from 5 to 95 wt % of a first surfactant which is selected from derivatives of alkyl polyglucosides and mixtures thereof; and (b) from 5 to 95 wt % of a second surfactant which is selected from: amphoteric surfactants, cationic surfactants, anionic surfactants, non-ionic surfactants, and mixtures thereof. This surfactant composition may be used to generate foam that is used for unloading a liquid from a hydrocarbon reservoir. It may be that the liquid unloading of foam generated using the surfactant composition is greater than that of foam generated from the first and second surfactants when they are foamed individually.

Abstract: The invention provides a foam control formulation in the form of a microemulsion, the formulation comprising: (a) from S to 70% w/w of primary surfactant, this surfactant having an HLB of from 1 to 12 and/or a cloud point of from 20 to 70° C.; (b) from 2 to 40% w/w of water-insoluble organic carrier liquid; and (c) water. Also provided is the use of this formulation to prevent and/or reduce foam in a fluid system, or as a processing aid to control foam production in a fluid system. The formulation may be used in an aqueous fluid system, such as an oilfield.

Abstract: Biocidal compositions including a phosphonium quaternary surfactant compound and a biopenetrant, wherein the biopenetrant includes an anionic polymer of an anionic unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, the polymer or copolymer being either terminated by vinylphosphonic acid (VPA) or vinylidene-1, 1-diphosphonic acid (VDPA) or having such monomers incorporated into the polymer backbone. The compositions preferably further include a quaternary ammonium salt cationic surfactant. The compositions optionally include a tetrakis(hydroxyalkyl)phosphonium salt biocide, wherein the salt is selected from sulphate, phosphite, bromide, fluoride, chloride, phosphate, carbonate, acetate, formate, citrate, borate, and silicate. Methods of using same are also provided.

Abstract: The invention provides a synergistic surfactant composition comprising: (a) a first amphoteric surfactant, which is selected from C8-C22 sultaines, salts thereof, and mixtures thereof; and (b) a second amphoteric surfactant, which is selected from C8-C22 betaines and salts thereof, C8-C22 propionates and salts thereof, and mixtures thereof. This surfactant composition may be used to generate foam that is used for unloading a liquid from a hydrocarbon reservoir. It may be that the liquid unloading of foam generated using the surfactant composition is greater than that of foam generated from the first and second surfactants when they are foamed individually.
