To realize the vision of automatic velocity model building with full-waveform inversion, a paradigm shift in the way seismic data are acquired is necessary. In December 2017 – January 2018 BP acquired 1000km of source lines over the deepwater sub-s

Evaluation of time-shift extraction methods on a synthetic model with 4D geomechanical changes
Autor: Chinaemerem Kanu, Mariana Gherasim, Linda Hodgson, Qie Zhang, Aoife Toomey, Bosen Du, Elizabeth L'Heureux
Publikováno v: The Leading Edge. 35:888-893
Imaging and characterizing time-lapse changes in reservoir properties rely on accurate estimation of the corresponding time shifts and amplitude changes. We evaluated the accuracy of competing time-shift extraction algorithms — cross correlation, n

Time-lapse imaging of a localized weak change with multiply scattered waves using numerical-based sensitivity kernel
Autor: Roel Snieder, Chinaemerem Kanu
Publikováno v: Journal of Geophysical Research: Solid Earth. 120:5595-5605
Multiply scattered seismic waves, due to their long path length within a finite volume, provide information that can be used to detect and image weak time-lapse changes within a medium. Such weak changes are usually not resolved with singly scattered

Time-lapse imaging of localized weak changes with multiply scattered waves
Autor: Roal Snieder, Ernst Niederleithinger, Chinaemerem Kanu
Publikováno v: SEG Technical Program Expanded Abstracts 2014.
Multiply scattered seismic waves, due to their long path length in a limited volume, provide information that can be used to detect and image weak timelapse changes within a medium. Such weak changes are usually not resolved with singly scattered wav

Arrest and recovery of frictional creep on the southern Hayward fault triggered by the 1989 Loma Prieta, California, earthquake and implications for future earthquakes
Autor: Chinaemerem Kanu, Kaj M. Johnson
Publikováno v: Journal of Geophysical Research. 116
[1] Theodolite measurements across the right-lateral Hayward fault, San Francisco Bay, California, show a dramatic reduction in surface creep rate from 5 to 10 mm/yr before the 1989 Loma Prieta earthquake to nearly zero creep rate after the earthquak
