AVO Inversion of a Mobil Data Set
-
Published:January 01, 1998
Abstract
The objective of the present work is to obtain estimates of the P- and S-wave velocities and densities of the subsurface. The inversion is carried out on 952 τ – p transformed CMP gathers, each containing 61 p values ranging from 0.05 to 0.35 s/km.
The forward modeling is performed by convolving the reflectivity with the wavelet, and it includes water bottom multiples, transmission effects, absorption and array filter effects. The basic assumption is that the subsurface is close to horizontally layered. A damped Gauss-Newton algorithm is used to minimize a least-squares misfit function.

Comparison of Seismic Inversion Methods on a Single Real Data Set

Papers in this volume explore the potential of a variety of seismic inversion methods applied to the same data set. They cover a wide range of topics, including effects of rock properties on seismic response, preparation of seismic data for AVO analysis, and a variety of AVO and inversion methods. The papers are an extension of a 1994 SEG postconvention workshop.
