Seismic scattering profile
WebStarting in late 2024, I am a PhD candidate working on numerical modelling of seismic wave generation by meteorite impacts on the surface of Mars. I am a member of NASA-led InSight mission that investigates the internal structure of Mars using seismology. My research involves using numerical simulations to constrain various properties of seismic waves … WebNov 1, 2024 · In the present study, we accurately estimated scattering and intrinsic attenuation from zero-offset vertical seismic profiling (VSP) and sonic data acquired from three wells that cross a...

WebSeismites are sedimentary beds and structures deformed by seismic shaking. The German paleontologist Adolf Seilacher first used the term in 1969 [1] to describe earthquake … WebWays in Which Seismic Waves Attenuate The attenuation of seismic waves is due to three effects: geometric spreading, intrinsic attenuation, and scattering attenuation. Geometric Spreading. Geometric spreading is simply the energy density decrease that occurs as an elastic wavefront expands.
WebTo demonstrate this approach for the seismic wavefield, we calculate dense seismic arrays for 10,000 synthetic seismograms, simulating a half-space consisting of sandstone and granite with a control source beneath the 10,000 synthetic stations. We modify the system by including bodies of changing size of sandstone with high hydrocarbon saturation.
WebPrevious studies performed in Abu Dhabi oilfields, United Arab Emirates, revealed the direct link of seismic wave attenuation to petrophysical properties of rocks. However, all those studies were based on zero offset VSP data, which limits the attenuation estimation at one location only.
