Abstract

An adequate monitoring program will be an intrinsic part of all CO2 storage projects, as required by regulations. This program must involve a surface monitoring component in addition to the subsurface methods. Should anomaly be detected, the monitoring program enters the costly confirmation modus, i.e., surveys to localize or dispel suspicion of an ongoing seep. Inverse methods applied to the tracer transport equation, using proper current statistics, are demonstrated here as a valuable tool to make predictions on where a seep might be located, and the flux associated with the source. The framework can be updated as new measurements are being collected.

Keywords: Geochemical modelling, GHGT-14, CO2 seep localization, CCS, marine monitoring, inverse problems, Bayesian methods
