S U M M A R Y Wide-angle seismic reflection traveltimes generated by large explosions are used extensively to obtain both velocity and regional structure of the crust and upper mantle. The method most commonly used to calculate interval velocities and thicknesses (layer parameters) of a multilayered earth. supposed to consist of homogeneous, isotropic and horizontal layers, is based on Dix’s ( ...

spectral decomposition or time-frequency representation (tfr) is a powerful tool for analyzing time varying nature of seismic data. mapping of a one dimensional seismic time trace to a two dimensional function of time and frequency reveals some characteristics of seismic signals that are not available in only time or frequency representations. this approach has been widely used in seismic explo...

Intracontinental deformation, caused by plate boundary processes, dominates the past and present tectonics of Syria (Figure 1). This deformation has created structures that form hydrocarbon traps in several different areas of the country. Current production from Syria is around 600 000 b/d and the country hosts ongoing exploratory efforts. Deformation within Syria can be conveniently divided in...

Seismic images and the geologic information they provide contribute significantly to our understanding of the earth’s subsurface. In this thesis, I focus on methods relevant for constructing and interpreting seismic images, including methods for velocity estimation, seismic imaging, and interpretation, which together address key aspects of reflection seismic data processing. Specifically, I pro...

High-resolution seismic reflection techniques successfully imaged structural features associated with a sinkhole that formed catastrophically as a result of dissolution of the Permian-age Hutchinson Salt in central Kansas. Symmetric steep sided chimney structure formed instantaneously, which over time has continued to gradually enlarge and elongate to the east, forming an open bowl. Orthogonal ...

Subsurface geological cross sections of 0 200 m depth were constructed using a dense drilling database of the Osaka Plain in the intra-arc Osaka Basin of the Japan island arc, an active plate margin. The cross sections revealed the subsurface geological structures and the geometry of folding and faulting in the basin. The comparison between the constructed subsurface cross sections and the seis...

Shallow seismic reflection marine profiles were collected in the area of Balaton Lake in Hungary using high frequency boomer techniques, in order to get information about the stratigraphy of the sedimentary layers. The noise in these shallow marine seismic reflection data is analyzed, and a series of traditional seismic data processing techniques is applied to improve the S/N ratio and coherenc...

Seismic interferometry allows one to create a virtual source inside a medium, assuming a receiver is present at the position of the virtual source. We discuss a method that creates a virtual source inside a medium from reflection data measured at the surface, without needing a receiver inside the medium and, hence, going beyond seismic interferometry. In addition to the reflection data, an esti...
