Impedance inversion may be obtained with:

WitrynaAcoustic impedance is used to produce more accurate and detailed structural and stratigraphic interpretations than can be obtained from seismic (or seismic attribute) interpretation. In many geological environments acoustic impedance has a strong relationship to petrophysical properties such as porosity, lithology, and fluid saturation. Witryna1. Introduction. Estimating reservoir parameters based on seismic data is one of the essential but challenging tasks in subsurface oil and gas reservoir exploration. Seismic impedance inversion is an effective method to get reservoir geophysical parameters from seismic or logging data. In the past decades, a series of impedance inversion ...
