Witryna10 kwi 2024 · The study aims to implement a high-resolution Extended Elastic Impedance (EEI) inversion to estimate the petrophysical properties (e.g., porosity, saturation and volume of shale) from seismic and well log data. The inversion resolves the pitfall of basic EEI inversion in inverting below-tuning seismic data. WitrynaWhen measuring impedance or admittance, which is a small-signal phenomenon, one must measure an input which can be a perturbation voltage or current. Then, an …
