Complete Q compensation involves the estimation of Q and then using the resultant Q to correct the amplitude and phase effects. In this paper, we present a ray based tomographic method that is derived from our previous work on amplitude tomography for estimating Q. The estimated Q can then be applied directly to migrated traces and uses raypaths information within a 3D Q model to restore amplitude and phase by integrating the Q effect along the rays. We demonstrate, through examples, how we include the estimated Q volume in the Q compensation process to fully account for attenuation and dispersion.
