Summary This paper presents the first results of the time-lapse monitoring from the full field ocean bottom life of field seismic system (LoFS) deployed by Shell at the deepwater BC-10 Argonauta field offshore Brazil, the deepest deployment of this technology in the world. The base survey was completed November 2013, shortly after start of production and the first monitor survey was obtained during June 2014, only 3 months after first water injection. The interpretation of high quality fast-track 4D data volumes identified some key 4D anomalies (softening, hardening, time-shifts) that show excellent correlation with the production and injection performance of the field, providing timely input to reservoir management decisions that are essential to enhance and maximize the oil recovery in this field.
