Effective corrosion inhibitor treatment in an upstream environment in oil and gas production requires a quite detailed picture of the physical processes present in the pipeline. This is particularly challenging in wet-gases, where most multiphase pipeline models have proven inadequate, and even those models that can be successfully applied to wet-gas pipelines do not produce all the output required for design and implementation of an effective corrosion inhibitor protocol. The Froude number, a dimensionless number generally under-utilized in multiphase pipeline design, has proven to be a very powerful qualitative and even quantitative tool for the evaluation of liquid-liquid mixing, droplet production, and drop-drop and drop-wall interactions. As such, it is the ideal correlating parameter to predict and quantify corrosion and corrosion inhibitor effectiveness.
