Detection of attenuation zones in a time section based on running window filtration

Research output: Contribution to journalArticlepeer-review


When developing oil reservoirs composed of carbonate rocks and those characterized by complex structure, the production well flow rate is largely determined by reservoir fracturing/ porosity rather than structure. These reservoir properties can often be reflected in a time section as significant attenuation of a seismic signal. The running time window spectral analysis has been proposed in the previous research to detect fractured zones. The calculations of seismic field diffraction due to a single pore and pore ensemble effects were made. The present research indicates that reservoir fracturing or porosity can cause qualitatively similar behavior of reflected signal amplitude spectra. Based on this finding, a rejection filter was constructed and applied to a real time section of the field in Tomsk Oblast, Prony and Fourier spectra being tested.
