The compressional-wave velocity VP and seismic-shot gathers can be used to determine the density p have very little influence on the dispersion thickness and shear-wave velocity of shallow curves of the Rayleigh waves.

CDP trace and refine these approximations The most advanced method (Oldenburq et al., by minimizing the rms deviation takinq into 1986) substitutes linear programmina consideration reqularization and constraints.
The lowest frequency (e.g. the mean) is best determined while higher frequencies are less In the conventional processing of band-limited seismic well determined.

Three different particle motion polarizations were All components of plastic waves in an isotropic used for both source and receiver, resulting in full 9-medium (Plexiglas) have hvc n recorded in a reflection seismics component recordings.
Historically, the acoustic or elastic wave equation was solved Algorithms based on this combined method resemble on a discrete grid using first or second-order diierencing in traditional finite-difference modeling algorithms in that they time and space (Kelly et al., 1976); (Marfun, 1984). The basic are explicit, time-marching solutions to wave equations.
The source is held stationary and is polarized in The effects of aligned fractures on seismic waves a fixed direction, but the receiver was rotated at the same needs to be understood before such data are used to location.

The high resolution seismic technique was sites in Pinawa area, Manitoba, Canada.

Here we have chosen to modify a recursive X-F migration scheme which we have used for redatuming, layer Of the many issues arising in the subsurface imaging of replacement and for a direct imagin 8. The algorithm has a land data, two of the most important are near-surface steep-dip capability, which is ideal or sltuattons where velocity effects and irregular surface topography. Both accurate redatuming is most needed, and is suitable for the combine to distort the subsurface picture.
This is a general system adaptable for delimitation and Due to the complexities of evaluation of anomalies from geophysical exploration conditions and exploration and geochemical data.
