Abstract

A receiver’s decimation study has been performed, using the PRM Jubarte dataset acquired by Petrobras, for assessing the potential of very sparse seabed acquisitions in conjunction of a high-order multiple imaging techniques. This imaging process make use of the multiple reflections to increase significantly the fold, enabling therefore sparser seabed recording geometry without compromising the 3D or 4D image quality. The presented decimation test consists on taking out receiver included into circular patches within a diameter of 600 m. The number of sensor is then reduced by a factor two. The results demonstrate that it is possible the break some established limit in term of seabed sensor sparseness without compromising the resolution of 3D/4D imaging.
