Inter-source passive body-wave interferometry by multidimensional deconvolution (MDD)

Abstract

Analogous to optical interferometry, scientists have developed seismic interferometry(SI) method, and its application in the field data have promoted the understanding and study of seismic wave propagation. Seismic interferometry can be applied to both controlled-source data and passive data. Under specific circumstances, the useful subsurface information can be retrieved with passive source seismic interferometry. In this paper, we first introduce the inter-receiver and inter-source MDD algorithm, and compare the MDD algorithm with inter-receiver cross-correlation algorithm. Then we use a simple three-layer geological model, using the above mentioned two methods to obtain the upper and lower reflector interfaces of the source, which can be used to obtain specific information about the formation.
