Seismic porosity and formation pressure logs are derived from seismic data exploiting novel characteristics of wavelet deconvolution and seismic inversion by modeling. In the first stage of wavelet deconvolution, the system wavelet is removed, and data are migrated to their true position. Thereafter, postmigration processing is performed in a.

In spiking deconvolution, it is assumed that the auto-correlation of the seismic trace is the same as the auto-correlation of the source wavelet, and that the reflectivity is random and its auto-correlation is a spike.

In other words, the desired output is. Purchase Deconvolution and Inverse Theory, Volume 29 - 1st Edition. Print Book Seismic Inversion and Deconvolution book E-Book. ISBN  Dictionary entry for Deconvolution () (de kon vō’ lū sh∂n) 1.A process designed to restore a waveshape to the form it had before it underwent a linear filtering action (convolution); inverse objective of deconvolution is to nullify objectionable effects of an earlier filter action and thus improve the recognizability and resolution of.

Gabor deconvolution (Margrave et al., ) is a recent attempt to incorporate data-adaptive inverse Q-filtering with a trace-by-trace deconvolution algorithm. This review of the present state of deconvolution has mostly focused on the impact of the various assumptions that are built in the standard wavelet processing flows of land data.

A lot of methods have been developed to improve the quality of seismic images. Download This book introduces readers to seismic inversion methods and their application to both synthetic and real seismic data sets. Seismic inversion methods are routinely used to estimate attributes like P-impedance, S-impedance, density, the ratio of P-wave and S-wave velocities and elastic impedances from seismic and well log data.

ISBNA paper by Hampson and Russell () outlined a modification of maximum-likelihood deconvolution method which allowed the method to be more easily applied to real seismic data.

One of the conclusions of that paper was that the method could be extended to use the sparse reflectivity as the first step of a broadband seismic inversion technique.

Optimal Seismic Deconvolution: An Estimation-Based Approach presents an approach to the problem of seismic deconvolution.

It is meant for two different audiences: practitioners of recursive estimation theory and geophysical signal processors. The book opens with a chapter on elements of minimum-variance estimation that are essential for all.

Abstract: This paper gives a review of current seismic techniques and future developments, with an emphasis on the to-day's key issue: seismic inversion (deconvolution and migration).

The introduction starts with a summary of acoustical echo-techniques and a description of typical features of the.

Inversion includes both seismic field data and well data, where well data serves to add the high frequency below the seismic band and to constrain the inversion. Well logs are first conditioned and edited to ensure there is a suitable relationship between impedance logs and the desired properties.

A step in seismic signal processing to recover high frequencies, attenuate multiples, equalize amplitudes, produce a zero-phase wavelet or for other purposes that generally affect the waveshape.

Deconvolution, or inverse filtering, can improve seismic data that were adversely affected by filtering, or convolution that occurs naturally as seismic energy is filtered by the Earth.

In this paper, we conduct a comparative study in the context of reflectivity inversion, to investigate the performance of curvelet deconvolution, least-squares method and L p -norm deconvolution. It is shown that by using curvelet deconvolution, the inverted reflectivity profiles have a better signal-to-noise ratio (SNR) and a higher resolution.

Öz Yilmaz has expanded his original volume on processing to include inversion and interpretation of seismic data. In addition to the developments in all aspects of conventional processing, this two-volume set represents a comprehensive and complete coverage of the modern trends in the seismic industry-from time to depth, from 3-D to 4-D, from 4-D to 4-C, and from isotropy to anisotropy.5/5(1).

Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by solving an inverse problem based on seismic measurements.

There are at least three fundamental issues to be solved simultaneously: non-linearity, non-uniqueness, and instability.

This paper proposes a time-varying wavelet estimation method to accommodate this problem. It uses matrix diagonalization to estimate a set of wavelets. Next, the time-varying wavelet is applied to deconvolution and seismic inversion.

The experiment shows that time-varying wavelet improves the results in both deconvolution and seismic inversion. In addition, at the stage of seismic inversion after deconvolution, total variation and a priori model are used as the regularization constraint terms to estimate inversion results with a blocky and laterally continuous structure.

The new method is successfully tested on the noisy synthetic seismic. Robust one-step (deconvolution + integration) seismic inversion in the frequency domain.

Acoustic impedance inversion can easily be computed by a standard impedance inversion algorithm which uses well logs to fill in the low-frequency information that is missing in bandlimited seismic data.

Various seismic deconvolution operators can be determined by estimating a seismic wavelet and subsequently designing an appropriate inverse filter which converts the wavelet to a spike.

In order for seismic inversion for rock. Sparse spikes deconvolution is one of the oldest inverse problems, which is a stylized version of recovery in seismic imaging. The goal of sparse spike deconvolution is to recover an approximation of a given noisy measurement T = W ∗ r + W 0.

Since the convolution destroys many low and high frequencies, this requires some prior information to regularize the inverse problem. adshelp[at] The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A.
