Integrated residual statics analysis with prestack time migration
نویسنده
چکیده
These shortcomings can be overcome if we have some way to estimate residual statics before velocity analysis. F-X filtered common offset gathers are used by Chan (1996) as the model for residual statics analysis before velocity is available, because the common offset domain is the only dimension in seismic surface geometry which is theoretically independent to the velocity information. Chan (1996) obtained good results on the random statics applied to Marmousi data.

Tomographic velocity estimation with planewave synthesis imaging
In areas with structurally complex geology, tomographic velocity analysis is required to estimate velocities. This paper describes a tomographic velocity analysis algorithm which uses planewave synthesis imaging as a prestack migration. In reflection tomography, prestack migration is required for both event picking and traveltime error computation. Traveltime errors are often measured in the fo...
متن کاملVelocity continuation and the anatomy of residual prestack time migration
Velocity continuation is an imaginary continuous process of seismic image transformation in the postmigration domain. It generalizes the concepts of residual and cascaded migrations. Understanding the laws of velocity continuation is crucially important for a successful application of time-migration velocity analysis. These laws predict the changes in the geometry and intensity of reflection ev...
متن کاملPrestack migration velocity analysis using wavefront synthesis
Common-reflection-point (CRP) gathers provide important clues in various migration velocity analysis schemes (Al-Yahya, 1987; Etgen, 1990). Conventionally, CRP gathers are obtained by prestack migration of shot records or constant-offset sections. This paper introduces a way to generate a CRP gather for residual velocity analysis using wavefront synthesis imaging. Compared to CRP gathers obtain...
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 کاملMigration and velocity analysis by velocity continuation
Residual and cascaded migration can be described as a continuous process of velocity continuation in the post-migration domain. This process moves reflection events on the migrated seismic sections according to changes in the migration velocity. Understanding the laws of velocity continuation is crucially important for a successful application of migration velocity analysis. In this paper, I de...
