B002 Operational Implementation of Full Azimuth High Density land Acquisition – 3D Irharen (Algeria) M. Girard* (Total SA) D. Mougenot (Sercel) C. Paulet (Total) A. Rhamani (Sonatrach) J.J. Griso (Cepsa) & Y. Boukhalfa (Enageo) SUMMARY Using a square spread of dense receiver stations (25 m) a full azimuth dense 3D survey (730 km² full fold 225) was recorded in 2005-06 over the Irharen gas discovery in Algeria. This land acquisition is representative of the coming trends aimed at improving reservoir illumination and anisotropy detection. If the basic square spread (7 200 channels) was defined from geophysical considerations its practical implementation
