Abstract:
A method for obtaining super source records in a marine application in which a target region is divided into a series of overlapping swaths. Seismic data is then collected for each swath using a fleet of vessels to traverse each swath. The fleet is intended to traverse each swath in a predetermined formation and substantially in unison. Seismic data is collected as each vessel alternates activating its seismic source at predetermined shotpoints along each swath, with reflection data collected by all the receivers after each shot. By careful planning, the proper traversal of numerous overlapping swaths results in a wide array of acquisition data for any given common source position. Super source records are attainable through the processing of this common source position seismic data. These super source records provide wide azimuth seismic data and can be processed to make high-quality seismic images.
