P003 Q ESTIMATION FROM VSP AND SURFACE SEISMIC AND ITS APPLICATION TO IMPROVE SEISMIC RESOLUTION Abstract 1 The propagation of seismic energy through the earth is affected by the attenuation of high frequencies and phase distortions due to Q the earth quality factor. The restoration of attenuation and dispersion effects in seismic data offers improved resolution and hence facilitates seismic interpretation. In this paper we present a case study from the Hassi R’mel field Onshore Algeria in which stable cumulative and interval Q profiles were obtained from zero-offset VSP and surface seismic data using a spectral ratio method. While the
