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.
