Biot theory proSvides a framework for computing the seismic response of fluid‐saturated reservoirs. Numerical implementation by 2-D finite‐differences allows investigation of the effects of spatial variations in porosity, permeability, and fluid

Much of the energy removed in a typical standard seismic data preprocessing sequence corresponds to approximately horizontal propagation in very near‐surface structure. Such energy includes direct (first‐break) compressional waves, direct shear w

Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics.
We evaluate the physical validity of surface boundary conditions of the computational model in reverse-time extrapolations of three-dimensional (3-D), three-component (3-C) elastic seismic data acquired at the earth’s free surface, using mathematic

We evaluated the applicability, of the Simultaneous Iterative Reconstruction Technique (SIRT) in a 3-D environment. Synthetic travel times were generated for various 3-D geometry configurations. We then inverted the synthetic travel times for velocit

Figure 10 (above) was wrongly identified in columns as a and b. It should have been identified as above showing a through f. Also The caption of Table 2 for this article should have referred to Figure 9 rather than Figure 5, and the caption for Table

The seismicity of western Canada has been studied for the period 1899–1975. The quality of the data collected improved through this period as the number of recording stations increased and the location and analysis methods developed, but significan
