The aim of seismic inversion is mapping all of the subsurface structures from seismic data. Due to the band-limited nature of the seismic data, it is difficult to find a unique solution for seismic inversion. Deterministic methods of seismic inversion are based on try and error techniques and provide a smooth map of elastic properties, while stochastic methods produce high-resolution maps of el...

Abstract Pre-stack seismic inversion is an effective method to estimate multiparameter from reflection data in the oil–gas reservoir exploration. In order get a reliable inverted parameter result, constrained model commonly used reduce multi-solution inversion. However, it hard appropriate by conventional well-log interpolation or velocity field offshore exploration with sparse wells. Envelope ...

one of the common problems in reflective seismic records is the existence of coherent linear and random noises which cause covering of the most important parts of reflective signals; therefore, it is necessary to attenuate them by processing methods. several processing techniques have been devised for attenuation of coherent linear noises and linear radon or ?-? transform is a powerful techniqu...

An extension of the open–source Bayesian AVO inversion program Delivery [1],[2] to time–lapse seismic inversion problems is described. The inverse problem is for a trace–wise layer–stack model comprising unknown layer–times, rock properties, fluid types and saturations, and pore pressure changes. The “data” are true–amplitude imaged/migrated seismic reflectivity traces, for arbitrary numbers of...

A new approach to seismic migration formalizes the classical diffraction (or common-tangent) stack by relating it to linearized seismic inversion and the generalized Radon transform. This approach recasts migration as the problem of reconstructing the earth’s acoustic scattering potential from its integrals over isochron surfaces. The theory rests on a solution of the wave equation with the geo...
