Gabor deconvolution: surface and subsurface consistent

David C. Henley, Gary F. Margrave and Carlos Montana

ABSTRACT

Nonstationary deconvolution methods are beginning to gain acceptance for routine seismic data processing, possibly in recognition of their ability to correct for the effects of anelastic attenuation. Gabor deconvolution has been introduced as a natural way to accommodate the temporal nonstationarity of seismic traces; and more recently, the underlying model has been extended to directly solve for lateral nonstationarity in the earth in a surface consistent way. The latest Gabor algorithm has recently been implemented as a test module in ProMAX, and it is constructed in such a way as to enable testing of various wavelet and Q function apportionment schemes for the estimation and removal of both surface and sub-surface dependent effects. The module also has the capability to iteratively improve the various wavelet estimates. This report describes the module and its parameters and shows some comparative examples of its output.
