Seismic Stratigraphic Modeling

This topic details the four basic rules to follow when acquiring seismic data for stratigraphic purposes and the four different processes for maximizing resolution in stratigraphic processing. It outlines two methods for extracting stratigraphic information from seismic data, describes lateral and vertical resolution and explains how these variables are used to interpret stratigraphic traps on seismic sections. The course lists three common sources used for acquiring seismic data and how their wavelets differ. Two variations in seismic amplitude responses due to changes in the type of pore fluid are defined. How the pore fluid type affects the seismic parameters of reflectivity, acoustic impedance and reflection coefficients are identified. The relationship between velocity and depth in terms of history and porosity is explained. The stratigraphic modeling categories are listed. The differences between forward and inverse modeling are outlined. The difference between one-dimensional and multi-dimensional modeling is described. How to generate a synthetic seismogram is discussed. The differences between an acoustic impedance log and a sonic log are identified. The inversion modeling process is described. The effects of attenuation and geometric spreading on inversion data is explained. Limitations with the AVO method are identified. The theory on which the AVO method is based is outlined.
