Evaluation of extended correlation on shallow Vibroseis data
نویسنده
چکیده
Knowledge of subsurface material response to seismic waves is important in developing a site-response model. Seismic velocities give insight into precautions that should be taken in anticipation of an earthquake. The method of fixed bandwidth extended Vibroseis correlation was used to extract reflections deeper than conventionally accomplished with only a 2-second listen time. A method to accurately suture data processed using standard correlation to data processed using extended correlation was developed to produce an S-wave velocity model and coherent image of the subsurface to a depth of 1 km.

Vibroseis Deconvolution with Maximum Likelihood Approach
The most commonly used deconvolution (Decon) method is based on minimum-phase assumption for the wavelet which is often not valid. Explosive energy source is close to minimum-phase which makes seismic data with explosive somewhat amenable to predictive Decon though the result is imperfect in phase. Decon of Vibroseis data is more problematic because the wavelet in a correlated Vibroseis trace i...
متن کاملOrthogonal sweeps of vibroseis
Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth’s reflectivity series. Historically vibratory seismic su...
متن کاملExamining the phase property of the nonstationary vibroseis wavelet
We have observed that Vibroseis wavelets behave very much as if they are minimum phase. This was discovered by applying minimum-phase Wiener deconvolution to the separated vibroseis VSP downgoing waves and observing that the result is effectively a band-limited spike. Motivated by this finding, we simulated a synthetic nonstationary vibroseis wavelet in a constant-Q medium by nonstationary conv...
متن کاملThe Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations
Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...
متن کاملNear-surface shear wave reflection surveys in the Fraser River delta, B.C., Canada
Shallow shear wave reflection surveys using high frequency vibroseis techniques provides information about the Tertiary bedrock surface and Pleistocene sediments on the Fraser River delta, in B.C., Canada. Besides the clear advantage of shear wave profiling in this shallow gas environment, the added resolution potential and ability to measure the shear wave velocity field enhances the fusion of...
