Active and integrated management of water resources throughout CO2 capture and sequestration operations
Court, Benjamin; Celia, Michael A.; Nordbotten, Jan Martin; Elliot, Thomas R. (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
Guo, B; Bandilla, Karl W.; Keilegavlen, Eirik; Doster, Florian; Celia, Michael A. (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 ... -
Detecting leakage of brine or CO2 through abandoned wells in a geological sequestration operation using pressure monitoring wells
Nogues, Juan P.; Nordbotten, Jan Martin; Celia, Michael A. (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
Dobossy, Mark E.; Celia, Michael A.; Nordbotten, Jan Martin (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 ... -
The impact of local-scale processes on large-scale CO2 migration and immobilization
Gasda, Sarah Eileen; Nordbotten, Jan Martin; Celia, Michael A. (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 ... -
A pore network model for calculation of interfacial velocities
Nordhaug, Hans Fredrik; Celia, Michael A.; Dahle, Helge K. (Peer reviewed; Journal article, 2003)Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for saturation ... -
Risk of Leakage versus Depth of Injection in Geological Storage
Celia, Michael A.; Nordbotten, Jan Martin; Bachu, Stefan; Dobossy, Mark E.; Court, Benjamin (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 ... -
A total pressure-saturation formulation of two-phase flow incorporating dynamic effects in the capillary-pressure-saturation relationship.
Dahle, Helge K.; Celia, Michael A.; Hassanizadeh, S. Majid; Karlsen, Kenneth Hvistendahl (Department of Applied Mathematics report, Research report, 2002-01) -
Two phase flow including interfacial area as a variable
Nordhaug, Hans Fredrik; Dahle, Helge K.; Espedal, Magne S.; Gray, William G.; Celia, Michael A. (Journal article, 2000)Based on the procedure of (Gray & Hassanizadeh 1998) we state macroscale conservation equations for multi phase flow in porous media including interfacial area as a variable. The phases we consider are a solid phase, a ...
