WebJun 16, 2014 · We analyze the gas reservoir characteristics by joint PP- and PS-waves, and use the amplitude and frequency decomposition attributes to delineate the gas reservoir … WebPS waves reflected from very shallow coal seams will generally arrive after near-surface noise that contaminates the corresponding P-wave reflection energy. In addition, P waves are influenced by pore space and/or fluid and gas saturation, while S waves are not. This is because S waves will only travel in solid materials.

WebWe develop the novel theory of transmitted PS migration and show that PS transmitted arrivals in a Gulf of Mexico vertical seismic profile (VSP) data set can be migrated to … WebBoth the P-wave and S wave (known at Ps) is picked up by the seismometer on the Earth's surface and can be used to analyze discontinuities within the Earth. In addition to these P and Ps waves, additional phases are created by multiple reflections. These phases include: PpPmp PpSmp, PpPms, and PpSms, as well as PsPmp, PsSmp, PsPms and PsSms.

WebMay 5, 2024 · Summary. Separation of PP and split PS waves in transversely isotropic media with a horizontal axis of symmetry is crucial for imaging subsurface targets and for fracture prediction in a multicomponent seismic survey using P-wave sources.In conventional multicomponent processing, when a low velocity zone is present near the … WebABSTRACT The shallow S-wave velocity model is difficult to accurately obtain in seismic exploration, resulting in poor imaging quality when traditional static correction methods are applied to PS-waves. Moreover, unlike for PP-waves, identifying an interface near the water table to use as the datum for PS-waves is almost impossible in many cases. We have …
