“…At the Kevin Dome proposed injection site, the Middle Duperow Formation, which lies at depth between 1231 m and 1236 m (4040 and 4704 ft), is a naturally fractured carbonate reservoir that is expected to have the capacity to store commercial quantities of CO 2 (between 300 and 740 MT) over an extended period of time (Bowen et al, 2012). Based on data collected from Danielson 33-17 (the proposed CO 2 producer) and Wallewein 22-1 (the target CO 2 injection well), characterization at the site was initially carried out by Bowen et al (2012) to understand the fracture network in this formation in relation to CO 2 sequestration potential. They found that the Duperow Formation (Fig.…”

“…The primary seal is a series of interbedded anhydrites and tight carbonates in the upper part of the Duperow and between the upper and lower porosity zones in the Duperow. Numerous secondary seals exist between the Duperow and the ground surface and have resulted in many oil and gas traps in shallower formations (Bowen et al, 2012).…”

“…Dolomite is not included because the kinetics of dolomite formation are slow and would not be applicable to the time scales being examined here (Morrow, 1982;Arvidson and MacKenzie, 1997). Duperow outcrops at the Montana Disturbed Belt also suggest possible dissolution and precipitation of secondary minerals (Bowen et al, 2012).…”

The Kevin Dome [Formula: see text] storage project, located in northern Montana, attempted to characterize the Duperow Formation as a potential long-term storage zone for injected [Formula: see text]. A multicomponent (9C) seismic survey was acquired for the Big Sky Carbon Sequestration Partnership over a portion of the Kevin Dome using P- and S-wave sources. Prestack migrated PP, PS, SH, and SV data sets were generated. We then applied several stratigraphic inversion workflows using one or several kinds of seismic wavefield at the same time resulting in joint inversions of each data set. The aim of our study is to demonstrate the benefits of doing quadri-joint inversion of PP-, PS-, SH-, and SV-wavefields for the recovery of the elastic earth parameters, especially the S-wave impedance and density. These are crucial parameters because they can help determine lithology and porefill in the reservoir characterization workflow. Because the inversion workflow always uses the original seismic data recorded in its own time domain, it is necessary to compute registration laws between PP-PS-, PP-SH-, and PP-SV-wavefields using a time shift computation procedure (warping) based on inverted S-wave impedances from inversion of a single wavefield. This generated a significant improvement over methods that rely on attempting to match trace waveforms that may have a different phase, frequency content, and polarity. Finally, we wanted to investigate the reliability of the quadri-joint inversion results in the Bakken/Banff Formations, which have less lateral geologic variation than the underlying Duperow target. This interval shares many of the geophysical characterization challenges common to shale reservoirs in other North American basins. We computed geomechanical parameters, such as Poisson’s ratio and Young’s modulus, which are a proxy for brittleness. Comparison of these results with independent laboratory measurements in the Bakken interval demonstrates the superiority of the quadri-joint inversion method to the traditional inversion using P-wave data only.
