A Logic Branch and Bound Algorithm for Petroleum Production Optimization Based on Generalized Disjunctive Programming
Hansen-Tangen, Jakob G.; Sangnes, Sindre Dombu (Master thesis, 2013)A new solution method for solving the real time production optimization (RTPO) problem for a petroleum production system is presented in this thesis. The objective function of the problem maximizes oil production and the ... -
Modelling and Optimization of Real-Time Petroleum Production - Using robust regression, bootstrapping, moment matching, and two-stage stochastic optimization
Morken, Marius Lie; Sandberg, Peter Tomassen (Master thesis, 2016)This work is concerned with the upstream sector of the petroleum industry and seeks to develop methods for real-time optimization of petroleum production under uncertainty. The real-time production optimization problem ... -
On decomposition and piecewise linearization in petroleumproduction optimization
Gunnerud, Vidar (Doktoravhandlinger ved NTNU, 1503-8181; 2011:164, Doctoral thesis, 2011)Maintaining good or optimal operations of large and complex petroleum assets isnot a trivial task. There are numerous decisions to be made where many of thedecisions affects each other. Relying entirely on human interpretation ... -
Optimization of investment decisions and production planning in aging offshore petroleum fields
Storvold, Vegard Svarlien (Master thesis, 2012)This thesis suggests that an optimization model can be used as decision support when different subsea solutions are evaluated in order to increase hydrocarbon recovery and production lifetime of a field. The Marlim field ... -
Optimization of offshore natural gas field development
Johansen, Gaute Rannem (Master thesis, 2011)In this thesis the target is to find the optimal development solution of an offshore natural gas field. Natural gas is increasing in importance as an energy source. Whilst most of the large oil fields have been developed, ... -
Optimization of Oil Production - Applied to the Marlim Field
Langvik, Andrea Sundby; Dzubur, Lamija (Master thesis, 2012)This thesis considers short-term petroleum production planning at the Marlim field operated by the Brazilian energy company, Petrobras. The production asset to be optimized is an Floating Production and Storage Operating ... -
Optimization of subsea investments: A combined investment and production strategy problem solved by combining optimization and simulation
Alfsen, Mats (Master thesis, 2013)Petroleum is one of our most valued resources, and our industrial civilization heavily relies on it. To meet the demand for petroleum, provide the highest economic contribution to the society and still comply with the ... -
Production Optimization in a Cluster of Gas-Lift Wells
Binder, Benjamin Julian Tømte (Master thesis, 2012)Subsea petroleum extraction systems may be large and complex, and many decisions affect the production. Maintaining high production levels is not a trivial task. As decisions are made based on available information and ... -
Real Option Valuation of Offshore Petroleum Field Tie-ins
Fleten, Stein-Erik; Gunnerud, Vidar; Hem, Øystein Dahl; Svendsen, Alexander (Journal article; Peer reviewed, 2011) -
Routing and Scheduling of Platform Supply Vessels: Case from the Brazilian Petroleum Industry
Friedberg, Daniel Oyra; Uglane, Vidar Thune (Master thesis, 2013)In this thesis we examine how Logistics in Petrobras may improve their decision making with regard to routing and scheduling of platform supply vessels (PSV). Petrobras are aiming to double their current production level ... -
Simulation based optimization of petroleum production problems: Development of a special purpose B&B for a non-convex MINLP
Ursin-Holm, Stine; Shamlou, Sheri S. (Master thesis, 2013)This work is concerned with the upstream and operational planning of petroleum fields. The short-term production optimization problem is modeled here as a simulation based non-convex MINLP problem. A special purpose B&B ... -
Subsea investments and well placements in the oil production industry
Haug, Eirik Røysem (Master thesis, 2013)Strengere krav fra myndigheter og en økende mengde aldrende olje- og gassfelt krever en stadig høyere utvinningsgrad for å gjøre feltene, og reservoarene lønnsomme. Dette prosjektet tester optimeringsmetoder i kombinasjon ...
