Abstract

The viscoacoustic wave equation is applied into least squares reverse time migration(LSRTM) algorithm, to compensate the energy attenuation and modify the phase shift caused by the anelastic property of the media. Test is conducted on cross-well seismic data of the Friendswood site in Texas. Compared to standard LSRTM, higher image quality is produced by Visco-acoustic LSRTM with Q compensation, especially in the low Q value area. It suggests that by using the viscoacoustic wave equation, the blurring and distortion in the migration image due to the attenuation effect can be well corrected.
