Collaborative optimization by shared objective function data
Angga, I Gusti Agung Gede; Bellout, Mathias; Bergmo, Per Eirik Strand; Slotte, Per Arne; Berg, Carl Fredrik (Peer reviewed; Journal article, 2022)This article presents a collaborative algorithmic framework that is effective for solving a multi-task optimization scenario where the evaluation of their objectives consists of two parts: The first part involves a common ... -
Effect of CO2 tax on energy use in oil production: waterflooding optimization under different emission costs
Angga, I Gusti Agung Gede; Bellout, Mathias; Kristoffersen, Brage Strand; Bergmo, Per Eirik Strand; Slotte, Per Arne; Berg, Carl Fredrik (Peer reviewed; Journal article, 2022)Tackling emissions from hydrocarbon production is a necessity because hydrocarbon production will last for a prolonged time. As a popular hydrocarbon production method, waterflooding operation is energy-intensive and ... -
Efficient flow diagnostics proxies for polymer flooding
Krogstad, Stein; Lie, Knut-Andreas; Nilsen, Halvor Møll; Berg, Carl Fredrik; Kippe, Vegard (Journal article; Peer reviewed, 2017)Flow diagnostics refers to a family of numerical methods that within a few seconds can compute visually intuitive quantities illuminating flow patterns and well connections for full 3D reservoir models. The starting point ... -
Efficient well placement optimization under uncertainty using a virtual drilling procedure
Kristoffersen, Brage Strand; Silva, Thiago Lima; Bellout, Mathias; Berg, Carl Fredrik (Peer reviewed; Journal article, 2021)An Automatic Well Planner (AWP) is used to efficiently adjust pre-determined well paths to honor near-well properties and increase overall production. AWP replicates modern geosteering decision-making where adjustments to ... -
Joint well-placement and well-control optimization for energy-efficient water flooding of oil fields
Angga, I Gusti Agung Gede; Bergmo, Per Eirik Strand; Berg, Carl Fredrik (Peer reviewed; Journal article, 2023)Hydrocarbon production driven by water flooding is energy-intensive. This paper presents well-placement and joint well-placement-and-control optimization studies with objective function taking into account emissions, ... -
Reduced well path parameterization for optimization problems through machine learning
Kristoffersen, Brage Strand; Bellout, Mathias; Silva, Thiago Lima; Berg, Carl Fredrik (Peer reviewed; Journal article, 2021)In this work we apply a recently developed machine learning routine for automatic well planning to simplify well parameterization in reservoir simulation models. This reduced-order parameterization is shown to be beneficial ...
