Abstract

SEISMIC WAVEs would be attenuated while transmitting in the earth layers. Determination of ATTENUATION mechanism in the earth and analysis of seismic data are very important. One of the most significant parameters in ATTENUATION of SEISMIC WAVEs is ATTENUATION coefficient (1/Q). ATTENUATION is limited by QUALITY FACTOR which describe the scattering in media. By increasing of ATTENUATION, QUALITY FACTOR would be decreased. One of the newest ways for estimation of Q is using VSP data (Vertical Seismic Profiling) by considering the decrease of frequency and amplitude in different depths for down going waves. In this research QUALITY FACTOR would be estimated by using zero-offset VSP data of two exploration wells in the south of Iran. Q would be estimated by AMPLITUDE DECAY METHOD and ANALYTICAL SIGNAL METHOD. We show that decreasing of Q maybe due to gas hydrocarbon existence.
