CUELLAR-URBANO, Mayra  and  CHAVEZ-PEREZ, Sergio. Acquisition Footprint Attenuation Driven by Seismic Attributes. Ing. invest. y tecnol. [online]. 2014, vol.15, n.2, pp.199-208. ISSN 2594-0732.

Acquisition footprint, one of the major problems that PEMEX faces in seismic imaging, is noise highly correlated to the geometric array of sources and receivers used for onshore and offshore seismic acquisitions. It prevails in spite of measures taken during acquisition and data processing. This pattern, throughout the image, is easily confused with geological features and misguides seismic attribute computation. In this work, we use seismic data from PEMEX Exploración y Producción to show the conditioning process for removing random and coherent noise using linear filters. Geometric attributes used in a workflow were computed for obtaining an acquisition footprint noise model and adaptively subtract it from the seismic data.

Keywords : geophysics; exploration seismology; seismic imaging; acquisition footprint; seismic attributes.
