An experimental study was conducted by use of a 6-in.-inner-diameter facility to analyze three-phase stratified wavy flow in horizontal pipelines. -
Use of surfactants and gas lift in combination to suppress severe slugging were tested. Surfactants were able to suppress severe slugging for most of the cases, and gas lift helped significantly.

A new methodology for oil/water horizontal pipe separator (HPS) design and performance prediction is developed. Separator diameter is determined on the basis of oil/water flow-pattern prediction. A batch separator model is adopted and modified to predict the separator length for desired quality.
