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 ... -
Simulating spatial and temporal varying CO2 signals from sources at the seafloor to help designing risk-based monitoring programs
Ali, Alfatih Omer Mohammed Ahmed; Frøysa, Håvard G; Avlesen, Helge; Alendal, Guttorm (Peer reviewed; Journal article, 2016-01)Risk-based monitoring requires quantification of the probability of the design to detect the potentially adverse events. A component in designing the monitoring program will be to predict the varying signal caused by an ... -
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 ...
