WebThe domain studied in the prestack wave migration is the lower half space, i.e. the underground of the Earth. The surface of the earth at z = 0 acts as a mirror in reflection wave propagation, producing a correction term to the integral in Eqn (5.8b).The correction term represents a new seismic phase from the reflective mirror with an imaginary source … WebReflected P ‐to‐ P and P ‐to‐ S converted seismic waves in a two‐component elastic common‐source gather generated with a P ‐wave source in a two‐dimensional model can be imaged by two independent scalar reverse‐time depth migrations.
WebDec 31, 1994 · Most migration methods are based on a variety of approximate versions of the wave equation, one notable exception being the finite-difference reverse-time depth migration algorithm. Since it requires enormous computer resources, its applications have been primarily restricted to 2-D synthetic data. Web3D Kirchhoff prestack depth migration (PSDM) sets the standard for depth imaging as a key component of the seismic toolbox. Our implementation images arrivals that propagate at 90° and higher angles as turning waves. Image quality is further improved by the ability to honor both vertical and tilted transverse isotropy (VTI and TTI).
WebDespite the name, Reverse-time Migration, or RTM, is in fact a depth migration. The “time” in the name refers to the propagation method, whereas the domain of output is depth, as for other depth migration methods. More fundamentally, RTM honours wave propagation fully. WebA new true-amplitude prestack elastic depth-migration algorithm includes compensation for transmission and anelastic attenuation losses in an isotropic medium. Geometric spreading and its compensation are incorporated by extrapolating up- and downgoing waves using a full two-way wave equation.
