Optimized field development often requires periodic acquisition of new seismic data that enables generating higher-quality seismic images. These seismic images can improve subsurface understanding, allowing identifying new targets and facilitating further investigation of remaining reserves; however, surface infrastructure development over time can create obstructions in the field area. These obstructions make marine streamer seismic acquisition at the vital parts of the field nearly impossible. One solution to overcome this acquisition challenge is to acquire hybrid surveys, using nodes positioned in the obstruction area and marine streamers outside. Our hybrid 3D surface seismic survey was acquired in a shallow-water (40m to 52m) infrastructurally obstructed area using both streamer and ocean-bottom system acquisition techniques. The acquisition was carried out by a single vessel using a triple-source configuration. We present various challenges encountered processing this hybrid survey and our solutions.
