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 the use of a surfactant as a corrosion inhibitor, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates. Also provided is a method of preventing or reducing corrosion of a metal component that is in contact with, or will be in contact with, an aqueous fluid, wherein the method comprises providing a surfactant and applying the surfactant to the metal component or adding the surfactant to the aqueous fluid that is in contact with, or will be in contact with, the metal component, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates.

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.

Abstract: The invention provides a foam control formulation in the form of a microemulsion, the formulation comprising: (a) from 5 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.
