Abstract: Method and system for acquiring seismic data. The method includes receiving an area to be seismically surveyed; receiving a sub-area that is smaller than area; determining a full seismic survey configuration, which includes streamer vessels and source vessels, to survey the entire area, wherein the full seismic survey configuration generates seismic data over the entire area; determining an in-fill process configuration that is different than the full seismic survey configuration, wherein the in-fill process configuration generates long offset seismic data over the sub-area; and sending the full seismic survey configuration to the streamer vessels and the source vessels.

Abstract: Method and system for generating a full acquisition path for a marine seismic acquisition system. The method includes receiving survey area information about a survey area to be seismically surveyed; selecting a radius (R) and a length (L) of a lace; selecting an overlap distance (OL) between first and second lanes; generating the full acquisition path by repeating the lace along a first lead line inside the first lane and along a second lead line inside the second lane and replicating the first and second lanes until the entire survey area is covered with laces; and sending the full acquisition path to a streamer vessel for performing the seismic survey.
