Abstract

A system and method for predictive flow assurance assessment by measuring at least one actual parameter related to a multiphase fluid mixture flowing in a main flow line, taking a sample from the multiphase fluid mixture flowing in the main flow line, modifying at least one control parameter of the sample until a transition appears, wherein said transition would cause a flow issue when occurring in the main flow line, detecting the transition of the sample and determining a corresponding transition value associated with the at least one control parameter, calculating a difference between the at least one actual parameter and the at least one transition value, said difference being representative of a margin relatively to a similar transition appearance in the main flow line causing a flow issue in the main flow line, and implementing a flow issue preventing step when the difference exceeds a given threshold.
