Compositions may contain an oleaginous base fluid, and a branched amidoamine surfactant prepared from the reaction of an alkylene amine or an oligoalkylene amine and a branched acid having a C4 to C24 primary hydrocarbon chain, and having one or more C1 to C24 branches. Methods may include emplacing a wellbore fluid into a wellbore, wherein the wellbore fluid contains an oleaginous base fluid; and a branched amidoamine surfactant prepared from the reaction of an alkylene amine or an oligoalkylene amine and a branched acid having a C4 to C24 primary hydrocarbon chain, and having one or more C1 to C24 branches.
组合物可包含含油基液,以及由亚烷基胺或低聚亚烷基胺与具有 C4 至 C24 主烃链并具有一个或多个 C1 至 C24 支链的支链酸反应制备的支链氨基胺表面活性剂。方法可包括将井筒流体注入井筒,其中井筒流体包含含油基质流体;以及由亚烷基胺或低聚亚烷基胺和具有 C4 至 C24 一级烃链并具有一个或多个 C1 至 C24 支链的支链酸反应制备的支链氨基胺表面活性剂。
