Double-difference waveform inversion of 4D ocean bottom cable data: Application to Valhall, North Sea
SEG Technical Program Expanded Abstracts 2013
Changes in reservoir properties resulting from extracting hydrocarbons and injecting fluid are critical to optimize production. These properties can be characterized using waveform inversions of time-lapse seismic data. The conventional approach for analysis using waveform tomography is to take the difference of seismic inversion obtained using baseline and subsequent time-lapse datasets that are imaged independently. By contrast, double-difference waveform inversion (DDWI) jointly invertsdoi:10.1190/segam2013-1318.1 fatcat:2o53bh225bez5izrzofowycqyu
