Application of time-lapse multi-component seismic inversion to characterize pressure and stimulation in the Niobrara and Codell Reservoirs, Wattenberg Field, Colorado

摘要

The Wattenberg field is the fourth-largest oil and ninth largest gas field in the United States (EIA, 2015). A multi-component time-lapse seismic study has been conducted by RCP and Anadarko Petroleum Corporation in the Wattenberg field. This study includes an integrated dataset with seismic, microseismic, FMI log interpretations, and completion information. As part of a horizontal drilling programme, the Niobrara and Codell formations were targeted. P-wave seismic and S-wave seismic were analysed as part of the time-lapse study before and after the completion of 11 horizontal wells in the study area.
