Amplitude balancing in [tau]-p domain
An approach to balance the amplitude of seismic data in the Ï -Ï domain is introduced in this study. The idea of amplitude balancing technique is based on the following observation: In the Ï -Ï domain, direct wave, ground-roll, primary reflection, multiple and refraction arrivals are located at …

A Geophysical Investigation Of The Northeastern Rim Of The St. Martin Impact Structure, Manitoba, Canada.
… two geophysical surveys and used selected data from a previous survey. The two methods I conducted were: a magnetic survey and seismic reflection profiling. Selected data from a previous gravity survey was used to supplement survey results. The magnetic survey was conducted using the total …

Seismic Imaging and Velocity Model Building in the Thrace Region, Northwestern Turkey: A Case Study
The aim of this research is to apply several seismic processing and imaging techniques to a raw 3D-land dataset and examine the quality of the subsurface images. This study uses a 3D-seismic dataset in the Thrace region of northwest Turkey that was acquired by Turkish Petroleum in 2006 covering an …

Subsurface imaging with reverse vertical seismic profiles
… imaging results from a 3D reverse vertical seismic profile (RVSP) dataset measured at a hydrocarbon bearing pinnacle reef in northern Michigan. The study presented many challenges in seismic data processing and imaging, as the survey geometry was unique in several ways. Reverse VSP, which …

Wavelets for approximate Fourier transform and data compression
… to the developments of several wavelet-based data compression techniques for image and seismic data. We propose an algorithm that uses the discrete wavelet transform (DWT) as a tool to compute the discrete Fourier transform (DFT). The classical Cooley-Tukey FFT is shown to be a special case of …

Discrimination and Enhancement of Fracture Signals on Surface Seismic Data
… on seismograms as discrete events.A number of data processing workflows were designed and examined to enhance these fracture signals and to suppress the reflections in seismic data. The workflows were first tested on a 2D synthetic data set, and then applied to 3D field data from the San Juan …
