Simultaneous lithofacies inversion from prestack amplitudes

SEG Technical Program Expanded Abstracts 2013, 2013
Lithofacies prediction from well and seismic data is the challenge for the oil and gas industry to accurately describe the subsurface geology. This paper describes how lithofacies represented by probability vectors can be inverted using simultaneously all the amplitudes corresponding to various distances between source and receiver (offset) reflecting ...

Prestack Kirchhoff inversion of common-offset data

Geophysics, 1987
Abstract In trying to resolve complex geologic structures, the pitfalls in employing the CDP method become evident. Additionally, stacking multioffset traces corrupts the amplitudes necessary for stratigraphic analysis. In order to preserve whatever structural and amplitude information is in the data, prestack processing should be ...

Prestack traveltime inversion for three-dimensional structure

Geophysics, 1989
Abstract An iterative method for determining three-dimensional (3-D) velocity fields is presented. The input data are offset-dependent traveltimes for primary reflections. 3-D traveltime derivatives (the Frechet derivatives) for the 3-D structure are derived.
