Interferometric Seismic Imaging
Claerbout’s daylight imaging concept is generalized to the general theory of interferometric seismic imaging (II). Interferometric seismic imaging is defined to be any algorithm that inverts crosscorrelated seismic data for the reflectivity or source distribution. As examples, we show that II can be used to image reflectivity distributions by migrating ghost reflections in passive seismic data,...
متن کاملInterferometric Seismic Imaging of Sparsely-sampled Data
Micro-seismicity induced by fluid migration can be used to monitor the migration of fluids during reservoir production and hydro-fracturing operations. The seismicity is usually monitored with sparse networks of seismic sensors. The sparsity of the sensor networks degrades the accuracy of the estimated event locations. This inaccuracy often makes it impossible to infer the fluid pathways at the...
متن کاملReverse-time-migration of multiply scattered seismic waves
Multiply scattered waves, including internal multiples, are rarely considered as signal when imaging with seismic waves. Reverse-time-migration techniques accurately handle the propagation of such complex scattered waves, but most of these techniques paradoxically do not fully utilize the illumination and energy of multiply scattered waves because these methods rely on the single-scattering ass...
متن کاملcrustal velocity structure beneath tehran based on teleseismic and mining explosion data recorded by tehran city seismic network (tcsn)
tehran, iran’s capital with a population of more than 10 million is located in the southern foothills of the alborz collision zone. the alborz mountain belt of northern iran results from the collision of a piece of the gondwana with eurasia in the late triassic (sengor et al., 1988). the alborz active mountain range which consists of several sedimentary and volcanic layers, with east-west trend...
متن کاملImaging moving targets from scattered waves
We develop a linearized imaging theory that combines the spatial, temporal and spectral aspects of scattered waves. We consider the case of fixed sensors and a general distribution of objects, each undergoing linear motion; thus the theory deals with imaging distributions in phase space. We derive a model for the data that is appropriate for any waveform, and show how it specializes to familiar...
