Colored Gabor Deconvolution

Gabor deconvolution achieves a non-stationary deconvolution operator that corrects for both wavelet shape and attenuation, which can improve the resolution of seismic data effectively. In this abstract, we proposed a new deconvolution approach for non-stationary seismic data using the colored Gabor deconvolution (CGD), which can achieve higher resolution by taking blue spectrum as the expected output. Variable-step sampling (VSS) which can resample the low-frequency area and subsample the high-frequency area is used to estimate the attenuation function reliably and improve the statistical efficiency. Synthetic and field examples show that the CGD can broaden the spectrum, improve the resolution of seismic data and make the reflection characteristics more reliable, which is more valuable in reservoir prediction.
