Abstract

Summary

The Big Sky Carbon Sequestration Partnership is a US CO2 storage project in the Duperow formation from the Kevin Dome structure located in Montana. The goal is to characterize the Duperow interval as a potential long-term storage zone for injected CO2. During the years 2013–2015, a North American company, Vecta Oil & Gas operated a multi-component seismic survey on behalf of the Partnership over Kevin Dome, using P- and S-wave sources. After processing of 3D-9C seismic data, pre-stack PP, PS, SH and SV datasets were generated and migrated in their corresponding time domains. We evaluate from the real case study the benefits of inverting jointly PP, PS, SH and SV prestack seismic data. We developed registration laws using inverted shear impedances from sequential inversions as the input to the registration process. This parameter choice represents a significant improvement over methods which rely on attempting to match trace waveforms which may have different phase, frequency content, and polarity. This real case study of multi-component pre-stack stratigraphic inversion is an elegant way of employing all modes of a multi-component acquisition to generate an optimal estimate of P-, S-wave impedances and density to determine lithology and fluid contents used by quantitative reservoir characterization.
