Abstract
Interpretation techniques are presented that aim at the estimation
of seismic velocities. The application of localized slant stacks,
weighted by coherency, produces a decomposition of multichannel seismic
data into single trace instantaneous slowness p(x, t) components.
Colour displays support the interpretation of seismic data relevant
to the near surface velocity structure. Since p(x, t) is directly
related to stacking velocities and the depth of reflection, or bottoming
points, in the subsurface, this data transformation provides a powerful
tool for the inversion of reflection and refraction data.
