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. WitrynaNeural networks have been applied to seismic inversion problems since the 1990s. More recently, many publications have reported the use of Deep Learning (DL) neural …

Witryna14 wrz 2009 · Every system may be regarded in a frequency domain displaying frequency logarithm on the X–axis and logarithm of module and/or phase angle of transfer function on the Y–axis (Bode plot) [1–3]. For the electrochemical system, the transfer function is, in fact, the impedance of an equivalent electrical circuit i.e., its … WitrynaImpedance inversion is an effective method to estimate the properties of subsurface model from poststack seismic data. However, owing to the low quality of seismic data and other reasons,... date to string codesys
