Previous HitThinNext Hit Bed Previous HitTuningNext Hit Analysis Using Previous HitAVONext Hit Stratigraphy Methods

Vaughn Ball

When conventional methods of seismic stratigraphy are applied to the Previous HitthinNext Hit bed problem, the final result is a function which relates a range of thicknesses to a range of impedances. Amplitude vs. Offset (Previous HitAVONext Hit) stratigraphy provides an analysis method that can substantially reduce the range of the solution. Previous HitAVOTop stratigraphy is not a simple extension of conventional seismic stratigraphy. The essential difference is that petrophysical modeling is introduced in order to parameterize the otherwise unwieldly attributes of density, velocity, and Poisson's ratio.
