Time-Lapse Monitoring Using Vertical Seismic Profiles (VSPs), Bell Creek Oil Field, Montana

The PCOR Partnership, led by the EERC, is working with Denbury Resources to study associated CO₂ storage incidental to commercial enhanced oil recovery at the Bell Creek oil field located in southeastern Montana. Site characterization, modeling, simulation, and reservoir monitoring were completed as part of the PCOR Partnership's assessment of associated storage at Bell Creek. As part of this effort, several seismic data sets have been acquired, including 2D and 3D surface seismic, vertical seismic profiles (VSPs), and passive seismic data. A baseline and two monitor 3D VSP data sets were collected at Bell Creek as part of the deep subsurface-monitoring program. The purpose of the surveys was to assess time-lapse changes in the reservoir due to CO₂ around two observation wells.
