Categorization of Norwegian Continental Shelf formations in terms of geological CO2 storage potentials
Allen, Rebecca; Nilsen, Halvor Møll; Andersen, Odd; Lie, Knut-Andreas (Journal article; Peer reviewed, 2017)In the present study, we use data published alongside the Norwegian Petroleum Directorate (NPD) storage atlases to further investigate the storage capacity of 23 formations found in the Norwegian Continental Shelf. Our ... -
On obtaining optimal well rates and placement for CO2 storage
Allen, Rebecca; Nilsen, Halvor Møll; Andersen, Odd; Lie, Knut-Andreas (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 ... -
Ranking and categorizing large-scale saline aquifer formations based on optimized CO2 storage potentials and economic factors
Allen, Rebecca; Nilsen, Halvor Møll; Andersen, Odd; Lie, Knut-Andreas (Journal article; Peer reviewed, 2017)The process of selecting a CO2 storage site involves evaluating many potentially suitable sites in terms of their storage potentials as well as their associated technical and economic limitations. As such, it is useful to ... -
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 ...
