APPLICATION OF SPECTRAL DECOMPOSITION, RGB BLENDING, AND AMPLITUDE VERSUS FREQUENCY (AVF) METHOD IN PENOBSCOT FIELD, NOVA SCOTIA, CANADA

Abstract

This study aims to delineate the existence of structures such as faults and channels, how frequency relates to structure especially thin structures and to see the distribu- tion of attenuation using continuous wavelet transform (CWT) spectral decompo- sition techniques, RGB blending, and AVF. Continuous wavelet transform (CWT) is a spectral decomposition method that applies translation and dilation of wavelet to generate time-frequency window. Spectral decomposition combined with RGB blending method aims to see the contrast of frequency anomalies in the results. The AVF method was also conducted to observe the distribution of attenuative zones and the characteristics of the structures in the Penobscot field, especially in the Wy- andot Formation, Petrel Member (+400 & 590). These three methods have been successfully used to identify fault and channel structures in the Penobscot Field, which are useful for prospects. With RGB blending, we can analyze the fault and channel from 3 frequencies (high, medium, and low). Meanwhile, the AVF results depict the distribution of attenuation, especially in fault and channel
