Quantitative analysis of time-lapse seismic monitoring data at the Sleipner CO2 storage operation
article
Quantitative analysis of time-lapse seismic monitoring data at the Sleipner CO2 storage operation has been reported. Quantitative verification of the whole plume is not a regulatory requirement for CO2 storage but is an interesting technical challenge. An alternative way of estimating the thickness of the topmost CO2 layer is by topographic analysis of the reservoir top. Stratigraphic inversion is used to better characterize reservoirs by integrating various kinds of information obtained at different scales, combining geological and geophysical information in a target oriented inversion process. It is hoped that more intrareservoir horizons can be detected and mapped can contribute to improved reservoir flow modeling. Quantitative interpretation can yield direct estimates of CO2 layer thicknesses, which, when integrated with spectral decomposition and constrained AVO can yield improved estimates of layer velocities.
