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.

STABILITY ANALYSIS OF FINITE DIFFERENCE METHOD FOR ONE WAY WAVE EQUATION
Asian Journal of Mathematics and Computer Research, 2022There are many problems in the field of science, engineering and technology which can be solved by differential equations formulation. In this paper we consider the convergence of finite difference method Lax -Wondroff one step, Lax- Wondroff two step methods and Backward time central space for solving one dimensional, time-dependent hyperbolic equation

A fast and accurate interpolation algorithm for one way wave equation migration
SEG Technical Program Expanded Abstracts 2008, 2008We propose an interpolation algorithm for one-way wave equation migration, which can allow the migration to take much bigger extrapolation step than usual, and is still accurate up to the dip limit of the one way propagator. The proposed interpolation algorithm is frequency dependent and applicable to any one way extrapolator which works in the ...

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

Time-domain behavior of wide-angle one-way wave equations
Geophysics, 1991Abstract The constant-coefficient inhomogeneous wave equation reads (1)∂2u(x,z,t)∂x2+∂2u(x,z,t)∂z2−1c2∂2u(x,z,t)∂t2=−δ(t)δ(r), where t is the time; x, z are Cartesian coordinates; c is the sound speed; and δ(.) is the Dirac delta source function located at the origin.
