The future of vibroseis for high-density wide-azimuth land acquisition

Julien Meunier*, Thomas Bianchi, Jean-Jacques Postel, and Roger Taylor of CGGVeritas explain the advantages of a single vibrator solution for wide-azimuth land data acquisition. High-density acquisition with wide- or multi-azimuth coverage is becoming more established throughout the E&P industry in both land and marine environments.Seismic data from these acquisition geometries are providing a step change in image quality for a wide range of geological settings and environments around the world. This improvement comes from some of the key advantages of wide-azimuth geometry: improved illumination, higher fold, superior noise and multiple attenuation and the possibility for higher resolution with smaller bin sizes. There are also specific data processing advantages such as scattered noise attenuation and better azimuthal sampling for fracture studies.
