We identified resonance due to poor geophone-borehole cou- pling in downhole microseismic data and proposed to use spik- ing deconvolution and relative spectrum analysis to remove its effect. The resonance may hinder the arrival time picking and contaminate microseismic waveform spectrum. We designed a spiking deconvolution filter to recover the impulse response of the earth. Also, we proposed to use relative spectrum anal- ysis to study microseismic source parameters. The applica- tion of deconvolution on Marcellus shale dataset improved the identifiability of the multiple arrivals. Additionally, the rela- tive spectrum analysis is more effective in revealing the actual spectrum characteristics of microseismic waveforms.
