    摘要： 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.

    摘要： The present invention provides the use of a sulfosuccinate as a corrosion inhibitor. In particular, the sulfosuccinate may be used to inhibit the corrosion of a metal component that is, or will be, in contact with an aqueous fluid, in order to prevent or reduce corrosion of the metal component. The sulfosuccinate may be used to inhibit corrosion of a metal component in an industrial aqueous system, such as a hydrocarbon plant; a chemical plant; a water plant; or a paper manufacturing plant, and in particular in an oilfield system or a downstream oil-related system.

    摘要： 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.

    摘要： The invention provides a synergistic surfactant composition comprising: (a) from 5 to 95wt% of a first surfactant which is selected from derivatives of alkyl polyglucosides and mixtures thereof; and (b) from 5 to 95wt% 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.
