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 ...

Figures 4 and 5 are step-by-step illustrations of the inversion process. Figures 4 (a), (b) and (c) show how the log-impedance is conditioned by removing a linear … Witryna1 mar 2024 · Start from a well-prepared initial model, during the inversion, the update direction is obtained by L-BFGS. To save the calculating cost, the update step is calculated analytically. Next, the well log synthetic test is used to show the good performance of the single-trace multiplicative regularized acoustic impedance (STMR … raytheon myworkday

The lithology column and logging data (GR and … Witryna29 lis 2024 · However, from a mathematical point of view, seismic impedance inversion is an inverse problem and is ill-posed. Due to the limitations of incompleteness, noise, and wavelet band limitations of the observed data, multiple geological models can usually be obtained to match the observed data. Witryna22 maj 2024 · Inverters are two-port networks used in many RF and microwave filters. The input impedance of an inverter terminated in an impedance ZL is 1 / ZL. … simply klassic
