Spill-point analysis and structural trapping capacity in saline aquifers using MRST-co2lab
Nilsen, Halvor Møll; Lie, Knut Andreas; Møyner, Olav; Andersen, Odd (Journal article; Peer reviewed, 2015)Geological carbon storage represents a substantial challenge for the subsurface geosciences. Knowledge of the subsurface can be captured in a quantitative form using computational methods developed within petroleum production. ... -
Streamline simulation of a reactive advective flow with discontinuous flux function
Zefreh, Masoud Ghaderi; Nilsen, Halvor Møll; Lie, Knut-Andreas; Raynaud, Xavier; Doster, Florian (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 ... -
The single-cell transport problem for two-phase flow with polymer
Raynaud, Xavier; Lie, Knut-Andreas; Nilsen, Halvor Møll; Rasmussen, Atgeirr Flø (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 ... -
Using sensitivities and vertical-equilibrium models for parameter estimation of CO2 injection models with application to Sleipner data
Nilsen, Halvor Møll; Krogstad, Stein; Andersen, Odd; Allen, Rebecca; Lie, Knut-Andreas (Journal article; Peer reviewed, 2017)A key part of planning CO2 storage sites is to devise a monitoring strategy with proper modelling support. Herein, we show how a simulation framework that incorporates adjoint-based sensitivities can be combined with ... -
Using simplified methods to explore the impact of parameter uncertainty on CO2 storage estimates with application to the Norwegian Continental Shelf
Allen, Rebecca; Nilsen, Halvor Møll; Lie, Knut-Andreas; Møyner, Olav; Andersen, Odd (Journal article; Peer reviewed, 2018)We use simplified methods to investigate how uncertainty in geological models affects practical CO2 storage capacities in large-scale saline aquifers. Our focus is on uncertainties in top-surface elevation, rock properties ... -
Vertical Equilibrium Flow Models with Fully Coupled Geomechanics for CO2 Storage Modeling, Using Precomputed Mechanical Response Functions
Andersen, Odd; Nilsen, Halvor Møll; Gasda, Sarah Eileen (Journal article; Peer reviewed, 2017)Vertical equilibrium (VE) models have proved to be attractive for simulation of \co storage scenarios. Their primary advantage is a substantial reduction in computational requirements compared to standard 3D simulation ... -
Virtual element method for geomechanical simulations of reservoir models
Andersen, Odd; Nilsen, Halvor Møll; Raynaud, Xavier (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, ...
