Assessing Model Uncertainties Through Proper Experimental Design
Hvidevold, Hilde Kristine; Alendal, Guttorm; Johannessen, Truls; Mannseth, Trond (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 ... -
Layout of CCS monitoring infrastructure with highest probability of detecting a footprint of a CO2 leak in a varying marine environment
Hvidevold, Hilde Kristine; Alendal, Guttorm; Johannessen, Truls; Ali, Alfatih Omer Mohammed Ahmed; Mannseth, Trond; Avlesen, Helge (Peer reviewed; Journal article, 2015-04-04)Monitoring of the marine environment for indications of a leak, or precursors of a leak, will be an intrinsic part of any subsea CO2 storage projects. A real challenge will be quantification of the probability of a given ... -
Monotonicity Conditions for Discretization of Parabolic Conservation Laws
Hvidevold, Hilde Kristine (Master thesis, 2009-06-02)In the recent years monotonicity of control volume methods for elliptic equations has been studied. A discrete maximum principle is established in Keilegavlen et al. [18], and a set of monotonicity conditions on general ... -
Quantifying uncertainties when monitoring marine environments in connection with geological storage of CO2

Survey strategies to quantify and optimize detecting probability of a CO2 seep in a varying marine environment
Hvidevold, Hilde Kristine; Alendal, Guttorm; Johannessen, Truls; Ali, Alfatih Omer Mohammed Ahmed (Peer reviewed; Journal article, 2016-09)Designing a marine monitoring program that detects CO2 leaks from subsea geological storage projects is challenging. The high variability of the environment may camouflage the anticipated anisotropic signal from a leak and ...
