Real-time Seismic Wave Modeling and Visualization
Current rising energy demand/supply ratio trends are forecast to continue into the foreseeable future. As a consequence, effective and efficient seismic surveying and processing techniques are required now more than ever. Unfortunately those outside of organizations with the resources to develop their own processing and/or visualization packages, or license proprietary third-party ones, must ma...
متن کاملParallel and Distributed Seismic Wave-field Modeling
Abstract: Elastic or acoustic wave-field modeling is an important part of seismic exploration. It can be used during the planning, processing and interpretation stages of seismic investigation. First attempts of using wave-field modeling were undertaken in the seventies by Alford, Kelly and others [1, 2]. These attempts were restricted by the limitations of computers at that time. Even now, com...
متن کاملModeling of global seismic wave propagation on the Earth Simulator
We use the Earth Simulator to model seismic wave propagation resulting from large earthquakes on a global scale. Simulations are conducted based upon the spectral-element method, a high-degree finiteelement technique. We include the full complexity of the Earth, i.e., a three-dimensional seismic wave velocity and density structure, a 3-D crustal model, the elliptical figure of the Earth as well...
متن کاملModeling Seismic Wave Propagation Using Graphics Processor Units (GPU)
The main drawback of the seismic modeling in 2D viscoelastic media on a single PC is that simulations with large gridsizes require a tremendous amount of floating point calculations. To improve computation speedup, a graphic processing units (GPUs) accelerated method was proposed using the staggered-grid finite difference (FD) method. The geophysical model is decomposed into subdomains for PML ...
متن کاملGPGPU-Aided 3D Staggered-grid Finite-difference Seismic Wave Modeling
Finite difference is a simple, fast and effective numerical method for seismic wave modeling, and has been widely used in forward waveform inversion and reverse time migration. However, intensive calculation of three-dimensional seismic forward modeling has been restricting the industrial application of 3D pre-stack reverse time migration and inversion. Aiming at this problem, in this paper, a ...
