To obtain an image of the earth’s subsurface, time-imaging methods can be applied because they are reasonably fast, are less sensitive to velocity model errors than depth-imaging methods, and are usually easy to parallelize. A powerful tool for tim

Summary Medium to small-scale structural details and heterogeneities of a medium, e.g., faults, pinch-outs, thin lenses, fracturing etc. are of crucial importance for prospecting and development of fractured reservoirs. Such details and heterogeneiti

Summary Time processing is still a fundamental and frequently used tool in seismic exploration. Processing steps like stacking, velocity analysis, time migration and interpolation are used in most workflows. Most traveltime approximations are limited

Surface-measured wavefront attributes are the key ingredient to multiparameter methods, which are nowadays standard tools in seismic data processing. However, most operators are restricted to application to isotropic media. Whereas application of an

Diffraction imaging can lead to high-resolution characterization of small-scale subsurface structures. A key step of diffraction imaging and tomography is diffraction separation and enhancement, especially in the full prestack data volume. We have co

Source localization is a fundamental problem in seismology. Current localization techniques often rely on homogeneous isotropic models, even if a survey region is known to be geologically complex or anisotropic. We investigated a model’s influence

Snell’s law describes the relationship between phase angles and velocities during the reflection or transmission of waves. It states that horizontal slowness with respect to an interface is preserved during reflection or transmission. Evaluation of

We propose a partial time demigration method for enhancing prestack data quality. It is based on a single square root equation in terms of midpoint displacement, half-offset and migration velocity. By applying the partial time migration followed by s

To obtain an image of the earth's subsurface, time domain methods can be applied as a first step. The implicit common reflection surface (CRS) approach provides a powerful tool for time imaging. We can perform a series of processes, e.g., stacking, t
