The upstream offshore multi-phase well-pipeline-riser installations are facing huge
challenges related to slugging flow: An unstable flow regime where the flow rates, pressures …

Slugging flow is a condition caused by a liquid obstruction at the riser base. It exhibits cyclic
behaviour. The cycle consists of a protracted time of no gas production at the riser's top …

Industrial needs are evolving fast towards more flexible manufacture schemes. As a
consequence, it is often required to adapt the plant production to the demand, which can be …

Gas-water two-phase flow widely exists in chemical industrial processes, which contains
multiple flow states such as bubble flow, slug flow, wave flow, etc. Transition states between …

The problem of classifying gas–liquid two-phase flow regimes from ultrasonic signals is
considered. A new method, belt-shaped features (BSFs), is proposed for performing feature …

Petroleum wells produce a combination of oil, gas, and water in what is called a multiphase
flow. This mixture is transported through flowlines to a tank separator that isolates and …

A method for classifying flow regimes is proposed that employs a neural network with inputs
of extracted features from Doppler ultrasonic signals of flows using either the Discrete …

The current offshore oil & gas multi-phase production and transportation installations have
big challenges related with the slugging flow: An unstable multi-phase flow regime where …

Severe-slugging flow in offshore production flowlines and risers is undesirable and effective
solutions are needed to prevent it. Automatic control using the top-side choke valve is a …

In an offshore pipeline-riser system, the critical opening of choke valve, ie, the maximum
permanent opening to eradicate severe slugging, plays an important role in both pipeline …
