Title:
Super-virtual refraction interferometry: Field data example over a colluvial wedge
Authors:
Hanafy, Sherif M.; Alhagan, Ola; Al-Tawash, Feras
Abstract:
The theory of super-virtual refraction interferometry was recently developed to enhance the signal-to-noise ratio (SNR) of far-offset traces in refraction surveys. This enhancement of SNR is proportional to N, and can be as high as N if an iterative procedure is used. Here N is the number of post-critical shot positions that coincides with the receiver locations. We now demonstrate the enhancement of SNR of the super-virtual refraction traces for seismic data collected over a normal fault in Saudi Arabia. Results show that both the SNR of the super-virtual data set and the number of reliable first-arrival-traveltime picks are significantly increased. © 2011 Society of Exploration Geophysicists.
