Methods of velocity determination and noise reduction in the processing of near-surface seismic reflection data.
(2000)
At the Gypsy Outcrop Site, OK, the depth of interest is less than 100 ft. 2-D seismic surveys used a shotgun as source. The signal/noise ratio is very poor. CMP stacking fails to produce interpretable reflections. Because ...
Geologically and well-log constrained quality factor (Q) analysis for seismic reservoir characterization.
(2005)
Measurements of P- and S-wave velocities are conducted on alternating layers of acrylic and aluminum. In this experiment, both thickness of the layers, and frequency of the propagating wave are varied. Based on these ...
Determination of seismic attenuation from surface and downhole measurements.
(2000)
Intrinsic attenuation measurement from VSP using spectral ratios is seriously affected by scattering, coupling variations, and difficulties in first-arrival isolation. An algorithm to estimate intrinsic attenuation from ...
