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 …

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 …

Unstable regimes occurring for multiphase flow in vertical risers have successfully been
stabilized using conventional linear control techniques. However, these control systems rely …

In this work, we consider the problem of daily production optimization in the upstream oil and
gas domain. The objective is to find the optimal decision variables that utilize the production …

This paper presents a nonlinear model predictive control scheme for stabilizing the well
pressure during oil well drilling. While drilling, a fluid is pumped through the drill string and …

This paper considers the problem of daily production optimization for a gas lift oil network
under the presence of parametric uncertainty. The objective is to find the optimal distribution …

Riser slugging is a flow regime that can occur in multiphase pipeline-riser systems, and is
characterized by severe flow and pressure oscillations. The irregular flow caused by riser …

A gas-lift oil well is an oil well that uses high-pressure natural gas to improve oil production.
This type of oil well is unstable if not enough gas is available for operation, when a …

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 …

Slugging is an undesirable multiphase flow regime occurring on oil production facilities. This
manuscript studies the dynamics of this intermittent phenomenon in view of suppressing it by …
