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 …

We solve the problem of stabilization of a class of linear first-order hyperbolic systems
featuring n rightward convecting transport PDEs and one leftward convecting transport PDE …

Detection of undesirable events in oil and gas wells can help prevent production losses,
environmental accidents, and human casualties and reduce maintenance costs. The scarcity …

We propose a novel simplified economic model predictive controller (EMPC) for supervisory
control of an offshore petroleum production network composed of two wells, a riser, and a …

Oil production employing gas lift techniques enable the production of no natural flow wells
and supply the energy lost in the reservoir caused by the field depletion, keeping the …

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 …

This work describes a simplified dynamic model for control and real time applications in
offshore deepwater and ultra-deepwater petroleum production systems. Literature about …

As an offshore oil well ages, it is common for the production system to face multiphase flow
problems such as limit cycles. This phenomenon, known as slugging in the jargon of the oil …
