One-way wave equation: Absorbing boundary and seismic migration
International Meeting for Applied Geoscience & Energy, 1992A fast order differential system is formulated for one-way waves based on the characteristic analysis of a first order hyperbolic system and the optimization of the approximating dispersion relation. Corresponding scalar one-way wave equations are also obtained which are similar to the 45O paraxial approximation of the wave equation but are more ...

One-way wave-equation migration of compressional and converted waves in a VTI medium
Geophysics, 2010Abstract In seismic reflection surveying, by recording both pressure and shear-wave reflections, one can increase the amount of information obtained about the subsurface rather than by recording pressure waves alone. Geologic structures that are not visible by using conventional pressure-data may possibly be imaged using shear waves ...

Steep Dip Imaging Using an Orthogonal One-way Wave Equation Migration
71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009An orthogonal one way wave equation migration method is implemented to solve the dip limitation of a one way wave equation. Stacking into the image of the conventional downward propagation of the source and receiver wave fields, a horizontal direction propagation is introduced to eliminate the dip limitation.

On reciprocity and energy conservation for one-way acoustic wave equations
The Journal of the Acoustical Society of America, 1996Acoustic reciprocity in stationary media at rest and energy conservation are widely recognized as fundamental properties of the sound field to be inherited by any successful paraxial approximation. Rigorous validity of the reciprocity principle for a parabolic equation (PE) solution in motionless media is of particular importance for the PE to be ...

Imaging Complex Salt Bodies with Turning-Wave One-Way Wave Equation Migration
68th EAGE Conference and Exhibition incorporating SPE EUROPEC 2006, 2006In this paper we propose a modified version of the one-way wave equation migration that can propagate wavefields to any possible direction. Also, we incorporate true amplitude corrections in the migration to enhance steep dips. With this new method, turning waves are properly imaged.

Parallel Algorithm for One-Way Wave Equation Based Migration for Seismic Imaging
2018Seismic imaging is the final stage of the seismic processing allowing to reconstruct the internal subsurface structure. This procedure is one of the most time consuming and it requires huge computational resources to get high-quality amplitude-preserving images. In this paper, we present a parallel algorithm of seismic imaging, based on the solution of
