Abstract

Summary

A depth migration method, that uses primaries and all orders of multiples, has been adapted to produce extended 3D and 4D images in the context of seabed acquisition. The technology has been validated using the Petrobras 4D datasets acquired during the deep-water Jubarte PRM pilot. As result of its application, the reservoir illumination has been significantly expanded to more than 100 km2 from an approximate 10 km2 coverage obtained from the conventional imaging of primaries. The resulting 4D signal shows a good match with the well trajectory, validating the use of all orders of multiples for 4D imaging studies.
