On Stolt stretch time migration
نویسندگان
چکیده
We implement Stolt-stretch time migration with an analytical formulation for the optimal stretch parameter and show how it improves the quality of imaging. By a cascaded f-k migration approach with this algorithm, we manage to obtain time migration results on real data comparable to Gazdag’s phase-shift method, with a high accuracy for steeply deeping events at a computational cost dramatically lowered.

Evaluating the Stolt - stretch parameter a
The Stolt migration extension to a variable velocity case describes the velocity heterogeneity with a constant parameter, which is related to the stretch transformation of the time axis. We exploit a connection between modified dispersion relations and nonhyperbolic traveltime approximations to derive an explicit expression for the stretch parameter. This analytical expression allows one two ac...
متن کاملEvaluating the Stolt stretch parameter
The Stolt migration extension to a varying velocity case (Stolt stretch) implies describing a vertical heterogeneity by a constant parameter (W ). This paper exploits the connection between modified dispersion relations and traveltime approximations to derive an explicit expression for W . The expression provides theoretically the highest possible accuracy within the Stolt stretch framework. Ap...
متن کاملPrestack Stolt residual migration for migration velocity analysis
This paper presents a method of Stolt residual migration applicable to prestack data. The method’s main merit is that instead of requiring an assumption about the magnitude of the new velocity model to which we want to residually migrate, it only calls for an assumption about the ratio of the reference velocity to the new one. Since the method is, in essence, a Stolt-stretch technique, it inher...
متن کاملPrestack residual migration in the frequency domain
Prestack Stolt residual migration can be applied to seismic images that are depth migrated using wavefield extrapolation techniques. This method has significant advantages over other methods that estimate interval velocity functions for depth migration. It is more accurate than methods that are based on focusing the stack of migrated images by a residual NMO operation, so it provides a more acc...
متن کاملRay based tomography using residual Stolt migration
In complex areas, residual vertical movement is not an effective method to calculate traveltime errors for image domain tomography. By scanning over velocity ratios using residual Stolt migration, a different criteria for a coherent image can be defined, and a traveltime error approximated. The resulting traveltime errors are more accurate, therefore the tomography procedure is more robust than...
