  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.

  本发明提供了一种增效表面活性剂组合物，它包括：(a) 第一种两性表面活性剂，它选自 C8-C22 脂肪烷烃、其盐和它们的混合物；(b) 第二种两性表面活性剂，它选自 C8-C22 甜菜碱及其盐、C8-C22 丙酸盐及其盐和它们的混合物。这种表面活性剂组合物可用来产生泡沫，用于从碳氢化合物储层中卸载液体。使用该表面活性剂组合物产生的泡沫的液体卸载能力可能大于第一种和第二种表面活性剂单独发泡产生的泡沫。

  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.
