Abstract
This reference manual is designed to enable more geophysicists to
appreciate static corrections, especially their limitations, their
relationship with near-surface geology, and their impact on the quality
of final interpreted sections. The book is addressed to those involved
in data acquisition (datum static corrections), data processing (datum
static and residual static corrections), and interpretation (the
impact that unresolved static corrections, especially the long wavelength
or low-spatial-frequency component, have on the interpretation of
the final section). Simple explanations of the underlying principles
are included in an attempt to remove some of the mystique of static
corrections. The principles involved are illustrated with simple
models; these are supplemented with many data examples. This book
details differences in approaches that must be considered among 2-D,
3-D, and crooked-line recordings as well as between P-wave and S-wave
surveys. Static corrections are shown to be a simplified yet practical
approach to modeling the effects of the near surface where a more
correct wavefield or raypath-modeled method may not be efficiently
undertaken. Chapters cover near-surface topography and geology; computation
of datum static corrections; uphole surveys; refraction surveys;
static corrections-limitations and effect on seismic data processes;
residual static corrections; and interpretation aspects. An extensive
index and a large list of references are included.
