Various approached have been introduced to extract as much as information form seismic image for any specific reservoir or geological study. Modeling of faults and fractures are among the most attracted objects for interpretation in geological study on seismic images that several strategies have been presented for this specific purpose. In this study, we have presented a modified approach of ap...

Wave-equation, finite-frequency imaging and inversion still face many challenges in addressing the inversion of highly complex velocity models as well as in dealing with nonlinear imaging e.g., migration of multiples, amplitude-preserving migration . Extended images EIs are particularly important for designing image-domain objective functions aimed at addressing standing issues in seismic imagi...

Single-scattering imaging consists of two steps: wavefield extrapolation, whose goal is to reconstruct source and receiver wavefields from recorded data, and an imaging, whose goal is to extract from the extrapolated wavefields the locations where reflectors occur. Conventionally, the imaging condition indicates the presence of reflectors when the propagation time of reflections in the source a...

Single-scattering imaging consists of two steps: wavefield extrapolation, to reconstruct source and receiver wavefields from recorded data, and imaging, to extract from the extrapolated wavefields the locations where reflectors occur. Conventionally, the imaging condition indicates the presence of reflectors when the propagation time of reflections in the source and receiver wavefields match. T...

This article addresses the question whether time-lapse seismic reflection techniques can be used to follow and quantify the effects of solution salt mining. Specifically, the production of magnesium salts as mined in the north of the Netherlands is considered. The use of seismic time-lapse techniques to follow such a production has not previously been investigated. For hydrocarbon production an...

I present the theory of interferometric imaging (II). Interferometric imaging is any algorithm that images crosscorrelated data for the reflectivity or source distribution. As examples, I show that II can image arbitrary reflectivity distributions by migrating ghost reflections in passive seismic data, generalize the receiver-function imaging method used by seismologists, and migrate free-surfa...

Marchenko redatuming allows one to use surface seismic reflection data to generate the seismic response at any point in the subsurface due to sources at the surface. Without requiring much information about the earth’s properties, the seismic response generated by Marchenko redatuming contains accurate estimates of not only the primaries, but also internal multiples. A target-oriented imaging m...

A B S T R A C T A new type of seismic imaging, based on Feynman path integrals for waveform modelling , is capable of producing accurate subsurface images without any need for a reference velocity model. Instead of the usual optimization for traveltime curves with maximal signal semblance, a weighted summation over all representative curves avoids the need for velocity analysis, with its common...
