Elastic 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...
متن کاملprestack depth migration using CFP gathers
The common-focus-point technology CFP describes prestack migration by focusing in two steps: emission and detection. The output of the first focusing step represents a CFP gather. This gather defines a shot record that represents the subsurface response resulting from a focused source wavefield. We propose applying the recursive shot-record, depthmigration algorithm to the CFP gathers of a seis...
متن کاملDepth Characterization of Shallow Aquifers with Seismic Reflection, Part II—Prestack Depth Migration and Field Examples
It is common in shallow seismic studies for the compressional-wave velocity in unconsolidated sediments to increase by a factor of four or more at the transition from dry or partial water saturation to full saturation. Under these conditions, conventional NMO velocity analysis fails and leads to large depth and layer thickness estimates if the Dix equation is assumed valid. Prestack depth migra...
متن کاملPrestack imaging of overturned reflections by reverse time migration
We present a simple method for computing angle-domain Common Image Gathers (CIGs) using prestack reverse time migration. The proposed method is an extension of the method proposed by Rickett and Sava (2001) to compute CIGs by downward-continuation shot-profile migration. We demonstrate with a synthetic example the use of the CIG gathers for migration velocity updating. A challenge for imaging b...
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...
