Abstract
A method for mitigating slugs in pipelines carrying multiphase mixtures of gas and liquid by adding a quantity of a surfactant selected from the group consisting of ethoxylated alcohols, polyglycosides and alpha olefin sulfonates to the multiphase mixture in the pipeline. After addition of a quantity of surfactant, a determination is made as to whether the quantity of surfactant added is sufficient to mitigate the slugs, and thereafter adjusting the quantity of surfactant added to an amount sufficient to mitigate the slugs.
