Seismic inversion and modeling for porosity detection
The inversion of seismic reflection data to acoustic impedance rock property data presents opportunities for improved interpretation leading to a significant reduction of risk in exploration and development drilling. While the traditional seismic section represents boundaries between impedance contrasts, seismic inversion output is layer-based, representing pseudo acoustic impedance logs at each common mid-point (CMP). The earth is correctly represented as a complex of geologic layers, and in this form, is immediately recognizable to both geophysicists and geologists. Modern inversion methods also incorporate wave shaping techniques in the inversion process. This facilitates both a correction to zero phase and the estimation and removal of wavelet sidelobes. The result is a reduction in tuning effects, and improved resolution. This, in turn, results in an enhanced interpretation and more accurate quantification of reservoir properties.
