Info

What is Flow Assurance? • Analysis of the entire production system to ensure that the produced fluids continue to flow throughout the life of the field. • Optimization of the design and operating procedures to cost effectively prevent or mitigate slugging, surge volumes, wax deposition, gelling, hydrates, asphaltenes, etc.
Key Flow Assurance Issues •Wax (Paraffin) – What is it? •A solid hydrocarbon which precipitates from a produced fluid •Forms when the fluid temperature drops below the Wax Appearance Temperature (WAT) •Melts at elevated temperatures (20°F+ above the WAT) •Rate of deposition can be predicted for pigging frequency
