Seismic modeling and imaging with the complete wave ~ Seismic modeling and imaging of the earths subsurface are complex and difficult computational tasks The authors present general numerical methods based on the complete wave equation for solving these important seismic exploration problems
Seismic Modeling and Imaging Making Waves by Phillip ~ Figure 3 An example of reversetime migration for a salt pillow model from Bording and Lines 1997 SEG publication “Seismic Modeling and Imaging With the Complete Wave Equation” Figure 3a shows an unmigrated stacked section few reflection events can be discerned on the seismogram
Seismic modeling SEG Wiki ~ Modeling based on oneway wave equations does not include multiples while modeling based on twoway wave equations includes multiples in the simulated wavefields In this appendix we shall not discuss the details of specific algorithms for seismic modeling which span a broad range of applications including 2D and 3D zerooffset and nonzero
Waves and Imaging Class notes 18 ~ the dynamic balance equation 11 when external forces rather than initial conditions create the waves Let us now explain how these equations are obtained from a linearization of Euler’s gas dynamics equations in a uniform background medium Con sider the mass density ˆas a scalar eld In the inviscid case conservation
PDF Seismic wave modeling for seismic imaging ~ In this paper we present a parallel algorithm of seismic imaging based on the solution of the oneway wave equation The algorithm includes parallelization of the data flow due to the multiple
The Seismic Wave Equation ~ struct and solve the seismic wave equation for elastic wave propagation in a uniform whole space We will show that two types of solutions are possible corresponding to compressional P and shear S waves and we will derive the equations for their velocities that we presented in the last chapter This will involve vector calculus
Chapter 7 Seismic imaging MIT OpenCourseWare ~ Chapter 7 Seismic imaging Much of the imaging procedure was already described in the previous chapters An image or a gradient update is formed from the imaging condition by means of the incident and adjoint elds This operation is called migration rather than backprojection in the seismic setting The two wave equations
PDF Seismic Modeling and Imaging Using Wave Theory for ~ Seismic Modeling and Imaging Using Wave Theory for Fault and Fracture Identification These all well known oneway wave equation imaging algorithms are applied to the data for obtaining
SEISMIC SURFACE WAVES Katedra Geofyziky ~ 41 Wave equations in terms of potentials 81 Model of the medium sources and prpagate along the Earths surface are referred to as seismic surface waves Despite some similarities which water waves and seismic surface waves display there are substantial differences in the forces producing them
