Active and integrated management of water resources throughout CO2 capture and sequestration operations
(Peer reviewed; Journal article, 2011)Most projected climate change mitigation strategies will require a significant expansion of CO2 Capture and Sequestration (CCS) in the next two decades. Four major categories of challenges are being actively researched: ... -
Application of Vertically-Integrated Models with Subscale Vertical Dynamics to Field Sites for CO2 Sequestration
(Peer reviewed; Journal article, 2014)To address the engineering questions on security issues of geological carbon sequestration (GCS), a broad range of computational models with different levels of complexity have been developed - from multiphase multicomponent ... -
Assessing Model Uncertainties Through Proper Experimental Design
(Peer reviewed; Journal article, 2013)This paper assesses how parameter uncertainties in the model for rise velocity of CO2 droplets in the ocean cause uncertainties in their rise and dissolution in marine waters. The parameter uncertainties in the rise velocity ... -
Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
(Peer reviewed; Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -
Detecting leakage of brine or CO2 through abandoned wells in a geological sequestration operation using pressure monitoring wells
(Peer reviewed; Journal article, 2011)For risk assessment, policy design and GHG emission accounting it is extremely important to know if any CO2 or brine has leaked from a geological sequestration (GS) operation. As such, it is important to understand if it ... -
An efficient software framework for performing industrial risk assessment of leakage for geological storage of CO2
(Peer reviewed; Journal article, 2011)In response to anthropogenic CO2 emissions, geological storage has emerged as a practical and scalable bridge technology while renewables and other environmentally friendly energy production methods mature. While an ... -
Field-case simulation of CO2-plume migration using vertical-equilibrium models
(Peer reviewed; Journal article, 2011)When injected in deep saline aquifers, CO2 moves radially away from the injection well and progressively higher in the formation because of buoyancy forces. Analyzes have shown that after the injection period, CO2 will ... -
The impact of local-scale processes on large-scale CO2 migration and immobilization
(Peer reviewed; Journal article, 2011)Storage security of injected carbon dioxide (CO2) is an essential component of risk management for geological carbon sequestration operations. During the injection and early post-injection periods, CO2 leakage may occur ... -
Models for CO2 injection with coupled thermal processes
(Peer reviewed; Journal article, 2014)Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes ... -
Risk of Leakage versus Depth of Injection in Geological Storage
(Peer reviewed; Journal article, 2009-02)One of the outstanding challenges for large-scale CCS operations is to develop reliable quantitative risk assessments with a focus on leakage of both injected CO2 and displaced brine. A critical leakage pathway is associated ... -
SUCCESS: SUbsurface CO2 storage–Critical elements and superior strategy
(Peer reviewed; Journal article, 2011)SUCCESS is a Center for Environmental Energy Research in Norway and performs research related to geological storage of CO2 in the subsurface. The SUCCESS centre is established by the Research Council of Norway together ... -
Upscaled modeling of CO2 injection and migration with coupled thermal processes
(Peer reviewed; Journal article, 2013)A practical modeling approach for CO2 storage over relatively large length and time scales is the vertical-equilibrium model, which solves partially integrated conservation equations for flow in two lateral dimensions. We ... -
Using sensitivities and vertical-equilibrium models for parameter estimation of CO2 injection models with application to Sleipner data
(Peer reviewed; Journal article, 2017-07)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 ... -
Vertical Equilibrium Flow Models with Fully Coupled Geomechanics for CO2 Storage Modeling, Using Precomputed Mechanical Response Functions
(Peer reviewed; Journal article, 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 ...
