On obtaining optimal well rates and placement for CO2 storage
(Journal article; Peer reviewed, 2017)Large-scale storage of CO2 in saline aquifers is considered an essential technology to mitigate CO2 emissions. Storage potential has mainly been estimated based on volumetrics or detailed simulations for specific injection ... -
Streamline simulation of a reactive advective flow with discontinuous flux function
(Journal article; Peer reviewed, 2018)Reactive transport in porous media with dissolution and precipitation has important applications in oil and gas industry and ground-water remediation. In this work, we present a simulation method for reactive flow in porous ... -
Successful application of multiscale methods in a real reservoir simulator environment
(Journal article; Peer reviewed, 2017)For the past 10 years or so, a number of so-called multiscale methods have been developed as an alternative approach to upscaling and to accelerate reservoir simulation. The key idea of all these methods is to construct a ... -
The single-cell transport problem for two-phase flow with polymer
(Journal article; Peer reviewed, 2016)Polymer injection is a widespread strategy in enhanced oil recovery. Polymer increases the water viscosity and creates a more favorable mobility ratio between the injected water and the displaced oil. The computational ... -
Unstructured Voronoi grids conforming to lower-dimensional objects
(Journal article; Peer reviewed, 2018)We present a novel mixed-dimensional method for generating unstructured polyhedral grids that conform to prescribed geometric objects in arbitrary dimensions. Two types of conformity are introduced: (i) control-point ... -
The use of flow diagnostics to rank model ensembles
(Peer reviewed; Journal article, 2021)Ensembles of geomodels provide an opportunity to investigate a range of parameters and possible operational outcomes for a reservoir. Full-featured dynamic modelling of all ensemble members is often computationally unfeasible, ... -
Virtual element method for geomechanical simulations of reservoir models
(Journal article; Peer reviewed, 2017)In this paper, we study the use of virtual element method (VEM) for geomechanics. Our emphasis is on applications to reservoir simulations. The physical processes behind the formation of the reservoirs, such as sedimentation, ...
