Web31 Jan 2024 · TFCWT has been used with seismic data to detect low-frequency gas shadows corresponding to the Iranian hydrocarbon field . Subsequently, TFCWT has been used to estimate the quality factor and extract the attenuation attributes of seismic waves . All of these applications show that TFCWT provides higher frequency resolution at low … WebTFCWT has optimum time-frequency resolution, i.e. higher frequency resolution at lower frequencies and higher time resolution at higher frequencies, which makes it useful for seismic data interpretation.

WebTFCWT is another approach wherein it displays spectral power of a given frequency in TWT time for any event and this can be seen against seismic background. Unlike CWT, whose response includes a range of up to 5Hz around the central frequency, TFCWT gives a deterministic response to a single frequency. WebSelf publishing .

The identification of true and false bright spots is the key of success of lithologic oil-gas reservoir exploration. The false ‘bright spots’ which are caused by thin-bed tuning effect are often present in post-stack seismic data.
