Reflection seismic

WebThe application of seismic interferometry provides a new approach to obtain useful information of subsurface structures using noise data. In this study we investigate the feasibility of passive seismic interferometry in anisotropic media. We simulate long duration passive noise measurements for a model containing a transversely isotropic layer with … http://large.stanford.edu/courses/2013/ph240/trehan2/

WebIt basically consists of two steps: (1) identification of acoustic discontinuities (horizons) and determination of relative traveltimes for various source-receiver positions (picking of horizons); and (2) local velocity model estimations by an iterative procedure (data inversion). Web8. apr 2024 · For a seismic reflection survey, geologists need something to generate noise, such as a large vibrating device, a controlled explosion, or a heavy object which can be dropped to create a sound wave. They also need geophones, sensitive listening devices which can be placed on the surface of the Earth to listen for the sound waves as they return. WebIn reflection seismology we record seismic pulses that are reflected from boundaries which separate layers that have different acoustic impedances. The acoustic impedance is the product of the velocity and density. Information in the seismogram which comes after the first arrival is important.
