Time-lapse characterization of the Niobrara reservoir from multi-component seismic data, Wattenberg Field, Colorado

摘要: Multi-component time-lapse data were acquired by RCP and Anadarko Petroleum Corp over a section of land within the Wattenberg Field to monitor hydraulic stimulation 11 horizontal wells drilled in mid-2013, targeting Niobrara Codell Formations (Figure 1). Multiple methodologies utilized extract azimuthal anisotropy signatures from pure mode seismic volumes order characterize in-situ induced fractures reservoir. The amplitude traveltime analysis poststack fast slow shear wave provided an estimated volume which is believed relate stimulated rock volume; prestack proved be higher resolution fracture characterization tool providing measures orientation density; compressional provide reservoir stress state.
