SEISMIC BOUNDARY REFLECTION APPROXIMATION BY AUTOREGRESSION AND RADON-FOURIER

Seismic modeling is an important method in predicting the reservoirs in the
subsurface. Forward modeling is employed to observe the elastic wave propagation
behavior in homogenous medium. The propagated seismic waves provide the
information about the reservoirs. As the subsurface contains the discontinuities and
the rock formations give rise to the seismic reflections. AGC is applied to enhance the
subsurface reflections. For these time series reflections Autoregressive (AR) model is
used to predict the average reflections that are gathered in common depth point with
deep and shallow explosion source of energy. The main objectiveofthis research is to
develop a model for seismic reflections in a fractured velocity model. Key input
parameters are velocity of P wave, velocity of S wave, density and fracture depth.
Two different boundary conditions; Clayton Engquist (CE) boundary condition and
Rigid boundary condition are taken onto the boundaries of velocity model.
