Prestack migration deconvolution
Poststack MD has been shown to be an effective method for attenuating migration noise, improving lateral resolution, and correcting for some migration amplitude distortion in 2-D and 3-D data (Hu and Schuster, 1998; and Hu and Valasek, 1999). In field data tests, poststack MD has successfully improved the 3-D poststack migration images (Hu and Valsek, 1999) obtained from both synthetic and fiel...
متن کاملDetection of Multiple Damages by Prestack Reverse-Time Migration
An approach to detect and image multiple damages in a platelike structure is presented. A structural health monitoring system (SHMS) with a linear array of actuators/sensors is proposed. The integrated actuators/sensors are used to activate/receive lowest-order antisymmetric A0 mode Lamb waves. A migration technique used in geophysical exploration and seismic prospecting is adopted to interpret...
متن کاملWave-equation prestack depth migration for sub-basalt P and converted wave imaging
We apply 2-D wave-equation prestack depth migration to a North Sea basalt dataset. High velocity and impedance contrasts across a basalt layer causes low P-wave reflection signal-to-noise ratio under the basalt. We first migrate the P-wave data with a provided depth velocity model, and then replace sub-basalt P-wave velocity with a simple estimate of shear wave velocity and migrate locally-conv...
متن کامل3-D prestack migration deconvolution
An undersampled acquisition geometry and a limited recording aperture often produces migration noise (i.e., acquisition footprint) that blurs the subsurface reflectivity image. Here, we develop a prestack migration deconvolution (MD) filter that deblurs the migration image. The MD filter is applied to 3-D prestack SEG/EAGE salt data as well as 3-D marine data from Alaska. Results show that MD c...
متن کاملApplication of G'/G-expansion method to the (2+1)-dimensional dispersive long wave equation
In this work G'/G-expansion method has been employed to solve (2+1)-dimensional dispersive long wave equation. It is shown that G'/G-expansion method, with the help of symbolic computation, provides a very effective and powerful mathematical tool, for solving this equation.
