Abstract

Spectral decomposition techniques provide a dimension to explore and extract the hidden information from signals. A number of spectral decomposition methods have been applied on borehole logs to extract and identify lithological boundaries, reservoirs etc. But these techniques lack in providing simultaneous high time and frequency resolution. We propose to use Continuous Amplitude Phase Spectral (CAPS) Transform that provides both high time/depth and high frequency resolution of both the amplitude and the phase spectra. Two wells from the Penobscot field: L-30 and B-41 with Gamma ray, sonic, density and neutron porosity logs were used for the analysis. The CAPS decomposition of the well log highlighted areas of interest; which were found to be in good agreement with the reported results.
