Reverse Time Migration = Generalized Diffraction Stack Migration
The standard reverse-time migration (RTM) algorithm is usually described as zero-lag correlation of the backprojected data with the source wavefield. The data are back-projected by a finite-difference algorithm, where each trace acts as a source-time history of a point source at the geophone location. This is a simple and easily understood migration method, but appears inflexible to improvement...
متن کاملPre-stack Kirchhoff Time Migration on Hadoop and Spark
Pre-stack Kirchhoff time migration (PKTM) is one of the most widely used migration algorithms in seismic imaging area. However, PKTM takes considerable time due to its high computational cost, which greatly affects the working efficiency of oil industry. Due to its high fault tolerance and scalability, Hadoop has become the most popular platform for big data processing. To overcome the shortcom...
متن کاملseismic imaging of complex structures by integrating pre-stack time migration and surface stacking methods
the conventional approach to seismic data analysis consists of two main steps: estimating seismic velocities, (the subsurface macro-model), and seismic imaging, (mapping of the reflected seismic energy to the reflector positions). the aim and the major challenge in the seismic data analysis is the construction of the best undistorted image. this challenge would be more problematic when geometri...
متن کاملParallel Implementation of Pre-stack Least-squares Migration for Distributed Systems
Least-squares wave-equation pre-stack depth migration is a computationally expensive algorithm, requiring repeated application of wave-field modeling and migration algorithms. We describe a parallel implementation of least-squares migration for distributed parallel computing systems using MPI. The implementation distributes both the storage and processing requirements. In storage, the migrated ...
متن کاملElastic Prestack , Reverse - Time Migration
Elastic prestack, reverse-time depth migration is applied to both synthetic data and four-component eld data from the Valhall area. Reverse-time extrapolation of the recorded multi-component data is by 2-D elastic nite di erence solution to the full wave equation. An eikonal solver is used to compute the acoustic traveltime from the source to the image points. By using horizontal inline and ver...
