Acoustic daylight imaging via spectral factorization: helioseismology and reservoir monitoring

Abstract

Helioseismology validates a long-standing geophysical conjecture that the crosscorrelation of noise traces may provide impulse-response seismograms. Initially, this concept has not been applied to hydrocarbon exploration and production. With the advances in electronics and communications, helioseismology can now be applied in this area. In particular, helioseismology now enables to continually record from permanent seismometers and process these data in real time with acoustic daylight imaging techniques and obtain low cost continual reservoir monitoring.
