摘要： The use of a composition that includes a metal salt and an oil soluble amine formaldehyde reaction product scavenges H2S that is present in aqueous fluids (e.g. produced water liquid streams), natural gas and in oil and mixtures thereof (e.g. mixed production streams that contain all three phases) better than either component when used alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over each component when used alone, in the same total amount. Non-limiting examples of the metal salt include zinc or iron carboxylates, and a non-limiting example of an oil soluble amine formaldehyde reaction product is the reaction product of dibutylamine with formaldehyde.
摘要翻译：使用包含金属盐和油溶性胺甲醛反应产物的组合物清除存在于含水流体（例如产生的水液体流），天然气和油以及其混合物中的H 2 S（例如包含所有的混合生产流三相）比单独使用时更好。所得到的清除剂组合显着提高了反应速率和总体清除效率，即相同量的单独使用时每种组分的容量。金属盐的非限制性实例包括锌或铁羧酸盐，并且油溶性胺甲醛反应产物的非限制性实例是二丁胺与甲醛的反应产物。

摘要： In a method for optimizing gas lift operations in the production of crude oil, a surfactant is injected into the an oil well such that the surface tension between a lift gas and the formation fluid being produced is reduced and/or a lift gas-formation fluid foam is formed. The reduction in surface tension and/or foam formation increases the efficiency of the lift gas for lifting the formation fluid to the surface. The surfactant is a silicone resin which may be combined with other surfactants, in some embodiments.

摘要： A drag reducing additive for heavy oil, such as crude oil, includes a polymeric alkyl-substituted phenol formaldehyde resin and a solvent having at least one of an ester (e.g. ethyl acetate), an aldehyde (e.g. butyraldehyde), and an aromatic hydrocarbon (e.g. toluene, xylene, and the like), or mixtures thereof. When used together with a diluent (e.g. condensate, naphtha, or the like), the additive may reduce viscosity of the combined oil, diluent, and additive by at least 20%, increase throughput by at least 6%, reduce power consumption by at least 3%, reduce the diluent proportion by at least 3%, or some combination of these effects, as compared with an otherwise identical heavy oil without the additive.

A high boiling point primary or secondary amine is added to the desired liquid hydrocarbon medium, and in one exemplary embodiment, the medium is then brought into contact with a separatory membrane such as a nanofiltration membrane. The permeate from the membrane is a highly purified hydrocarbon stream.
