Abstract

Summary

Oil and gas exploration, Biot Theory, and numerical simulation have allowed the development of modeling of elastic wave propagation in environments similar to those found in the exploration of reservoirs, where the Biot Theory can be solved by the finite difference methods. In this paper was modeled the propagation of a plane wave through three models with different porosities of 5%, 10% and 15%, saturated with water. From the modeling, three seismograms were achieved in time, then were analyzed spectrally. Afterwards, the quality factor as a function of frequency and porosity was calculated, also compressional wave velocity as a function of porosity was calculated. Finally it was concluded that the attenuation, dispersion and travel time of seismic waves increases with the porosity and the wave velocity, dominant frequency and quality factor decrease with porosity.
