Coal-bed Methane reservoir identification using the natural source Super-Low Frequency remote sensing

The goal of this paper is to develop and analyze the natural source Super-Low Frequency (SLF) remote sensing using the BD-6 detector and its data processing and interpretation system to help with Coal-bed Methane (CBM) reservoir information extraction. We delineated the diagram of the SLF remote sensing technique, and especially illustrated the integrated method of the Independent Component Analysis (ICA) and Wavelet-Lifting Wavelet Transform to suppress time-varying 150Hz and 250Hz power frequency electromagnetic interference (EMI). In the application of interpreting enrichment layers of (CBM), we obtained the SLF interpretation signs to identify CBM reservoirs and features. The result demonstrates that the SLF remote sensing provides a prosperous perspective on the detection and demarcation of underground geo-objects.
