Pdf An Elastic Reverse Time Migration Method For Vertically

Pdf An Elastic Reverse Time Migration Method For Vertically Pdf | following the isotropic elastic reverse time migration (rtm), an elastic rtm method for vti media is proposed. Following the isotropic elastic reverse time migration (rtm), an elastic rtm method for vti media is proposed. the proposed method exploits polarization vector projection to separate anisotropic elastic wavefields.

Pdf Least Squares Reverse Time Migration In Elastic Media To resolve these issues, a new elastic reverse time migration method is developed to correct the anisotropy effect in vertical transversely isotropic media with surface topography. The reverse time migration method is based on two way wave equations which can accurately describe fully dynamic and kinematic characteristics of the wavefield in complex structural areas. This page is a summary of: an elastic reverse time migration method for vertically transversely isotropic (vti) media, may 2017, society of exploration geophysicists,. To overcome these issues, we developed an efficient and accurate adaptive variable grid discretization method that automatically selects the vertical grid size based on the velocity, depth, and dominant frequency of the wavelet in elastic medium.

Pdf Vector Based Elastic Reverse Time Migration Based On Proposed This page is a summary of: an elastic reverse time migration method for vertically transversely isotropic (vti) media, may 2017, society of exploration geophysicists,. To overcome these issues, we developed an efficient and accurate adaptive variable grid discretization method that automatically selects the vertical grid size based on the velocity, depth, and dominant frequency of the wavelet in elastic medium. We use elastic least squares reverse time migration (lsrtm) to invert for the reflectivity images of p and s wave impedances. elastic lsrtm solves the linearized elastic wave equations for forward modeling and the adjoint equations for backpropagating the residual wavefield at each iteration. In this paper, we use elastic modeling process to generate p&s shot records. then we use acoustic rtm and least squares rtm to migrate these elastic data, using p and s velocities in different experiments. This paper addresses two key aspects of this method: fundamental principles and stability conditions, and presents a strategy for its implementation on gpu.
