SYSTEM AND METHOD FOR ROCK PROPERTY ESTIMATION OF SUBSURFACE GEOLOGIC VOLUMES

摘要

A system and model for estimating rock properties may include receiving an initial reservoir model of the subsurface, calculating p-dependent reflection coefficients and vertical travel times at each boundary in the initial reservoir model, performing a Discrete Fourier Transform using the reflection coefficients and travel times to get a temporal spectrum of the reflectivity trace, multiplying by the temporal spectrum of a desired wavelet, performing an inverse DFT, and extracting the amplitude values at the vertical travel times for each boundary to generate synthetic seismic data. This synthetic seismic data may be compared with recorded seismic data to update the reservoir model.
