Two phase of waxy crude oil-water in horizontal pipes

Water produced along with the crude oil during production and transported together in a pipeline is a common occurrence in a petroleum production system. Understanding the behavior of crude oil-water flow in a pipe is crucial to many engineering applications, such as design and operation of flow lin...

The investigations proved that pressure drop was greatly influenced by flow pattern and mixture velocity. It was also found that the water holdup decreased slightly at higher water cuts due to the presence of emulsion in the crude oil – a great challenge when using a waxy crude oil in a two phase flow system.
