THE EFFECT OF FILTER Q INVERSION ON AMPLITUDE INSTANT (INSTANEOUS AMPLITUDE) SEISMIC DATA

PENGARUH INVERSI FILTER Q TERHADAP AMPLITUDO SESAAT (INSTANSTANEOUS AMPLITUDE) DATA SEISMIK

Abstract

Seismic waves travelling through media are attenuated by the conversion of elastic energy into heat. Upon
being attenuated, the travelling wave changes: amplitude is reduced, travelling waveform is modified due to
high-frequency content absorption, and phase is delayed. In this study, the effect of attenuation on seismic data
was reduced by applying inverse Q filter method. Application of inverse Q filter on seismic data, can improve the
quality and resolution of data. Improving the seismic data quality and its resolution can be seen at seismic
attributes (Instantaneous Amplitude) of seismic data. The results of study indicate that the seismic attributes
(instantaneous amplitude) would be better if the inverse Q filter was applied.
