Network-Constrained Production Optimization by Means of Multiple Shooting
Silva, Thiago Lima; Codas, Andrés; Stanko, Milan; Camponogara, Eduardo; Foss, Bjarne Anton (Journal article; Peer reviewed, 2019)A methodology is proposed for the production optimization of oil reservoirs constrained by gathering systems. Because of differences in scale and simulation tools, production optimization involving oil reservoirs and ... -
Non-linear model predictive control for an oil production network based on gas-lift
Lund, Thomas (Master thesis, 2014)Control and optimization of an oil production network based on gas-lift is a difficult task with challenges including well fluid flow oscillations and pipeline slugging which can lead to instabilities in the system. A ... -
Nonlinear Model Predictive Control (NMPC) of Separation Trains
Tollefsen, Trond (Master thesis, 2009)An evaluation of Modelica Fluid Library 1.0 has been performed and the new library has been found to be more efficient both during modelling and during computations than the beta version of the library. The separator model ... -
A nonlinear model predictive control scheme for sensor fault tolerance in observation processes
Knudsen, Brage Rugstad; Alessandretti, Andrea; Jones, Colin N.; Foss, Bjarne Anton (Peer reviewed; Journal article, 2020)This article addresses the problem of designing a sensor fault‐tolerant controller for an observation process where a primary, controlled system observes, through a set of measurements, an exogenous system to estimate the ... -

Optimal Voltage Control of the Southern Norwegian Power Grid: Mixed Integer Nonlinear Programming (MINLP) for Control and Optimization of the High Voltage Southern Norwegian Power Grid
Hannisdal, Erik Lundegaard (Master thesis, 2011)This thesis contains the synthesis, analysis and simulation results of an automatic optimal voltage controller for the Southern Norwegian power grid. Currently the high voltage power grid is controlled manually by operators ... -
Optimalisering av LNG-verdikjeden
Dahl, Kristoffer (Master thesis, 2007)Hovedmålet i hovedoppgaven er å utvikle en effektiv metode for å optimalisere driften av Statoils LNG anlegg ved uforutsette hendelser som forsinket skipsankomst og problemer med en produksjonsbrønn. -
Optimization Algorithms for Short-Term Production Planning
Hanssen, Kristian Gaustad (Master thesis, 2009)In an oil and gas production system, where wells are connected to manifolds with multiple pipelines, a complex optimization problem arises. The objective will typically be to maximize the oil production, while respecting ... -
Optimization of the Water-Flooding Process in a Small 2D Horizontal Oil Reservoir by Direct Transcription
Heirung, Tor Aksel N.; Wartmann, Michael R.; Jansen, Jan Dirk; Ydstie, Birger Erik; Foss, Bjarne Anton (Journal article; Peer reviewed, 2011) -
Optimization of water-borne crude oil transport
Vatn, Karsten Dånmark (Master thesis, 2007)A ship scheduling problem in optimization of water-borne crude oil transportation has been investigated. The classic optimization problem the most closely related to the problem at hand is the Multi-Vehicle-Pick-up-and-Delivery ... -
Parameter Estimation of Axial Pipe Movement of an Oil Field Drill String
Holhjem, Eirik Wilhelmsen (Master thesis, 2017)Drill strings are long slim rods used in well drilling to transmit torque and weight to the drill bit from the surface. As a consequence, these narrow structures experience various vibrations that could damage the well ... -
Penalty Function Approaches for Proactive Fault-Tolerant Model Predictive Control
Brusevold, Jon Håman (Master thesis, 2015)In the event of actuator faults in systems, standard control algorithms might not be sufficient for stabilizing the system and keeping the performance at an accept- able level. Because of this, fault-tolerant control methods ... -
Petroleum production optimization - A static or dynamic problem?
Foss, Bjarne Anton; Knudsen, Brage Rugstad; Grimstad, Bjarne André (Journal article; Peer reviewed, 2018)This paper considers the upstream oil and gas domain, or more precisely the daily production optimization problem in which production engineers aim to utilize the production systems as efficiently as possible by for instance ... -
