High-pressure transients don’t give operators much time to react. One moment, the system is stable; the next, a rapid surge pushes pressures far beyond what downstream equipment was ever designed to tolerate. In fast-moving conditions, unexpected valve closures, abrupt well shutdowns, and rapid restart sequences, the difference between a controlled response and a system-threatening event…

Wax and asphaltenes rarely create problems abruptly.  They deposit over time under steady-state operating conditions.  As they deposit, the frictional pressure drop rises primarily due to a decrease in the area available for flow and to a lesser extent to an increase in the roughness of the uneven surface of the deposit on the pipe…

Hydrates rarely cause trouble at convenient times. They form when conditions align to the right combination of temperature, pressure, water availability, and gas composition, often during ramp-up, cooling down, or recovery from a transient event. The shift can happen quietly: a pressure drop here, a temperature dip there, and suddenly, flow assurance teams are managing…

A Mechanism-Based, Operationally Realistic View Slugging is a non-trivial transient phenomenon that is highly sensitive to flow rates, velocities, and the pipe angle. This dependence and the inherent limitations of state-of-the-art commercial simulators make it difficult to predict all slug properties accurately. Real-time transient models do not solve slugging. Their value lies in improving situational…
