DOI: 10.1007/s10596-021-10052-3
Abstract: Seismic imaging faces challenges due to the presence of several uncertainty sources. Uncertainties exist in data measurements, source positioning, and subsurface geophysical properties. Reverse time migration (RTM) is a high-resolution depth migration approach useful for… read more here.

DOI: 10.1134/s1064562417050088
Abstract: Seismic waves propagating in a fractured geological medium are numerically simulated. Their dynamic behavior is described using a linear elastic model with an explicit description of all crack boundaries (a contact discontinuity problem is solved).… read more here.
