20120134235 | Areal Marine Seismic Exploration Method - Autonomous self-pop-up multicomponent bottom nodes (self-pop-up nodes SPN) are deployed to the bottom of an exploration area along parallel lines of exploration at specified spaced points by a recording vessel. At least one seismic source mounted on a shooting vessel continuously fires seismic energy. The shooting vessel travels between the SPN deployment lines. The direction of the sailing direction is parallel to the aforesaid lines. A source vessel is initially located at a distance from the first SPN deployment line. Every SPN records seismic waves. Upon the source vessel passes the half of the lines, the recording vessel starts on-going relocation of the deployed SPNs to the next exploration lines starting with the SPNs on the first exploration line. Collection of SPNs occurs by the recording vessel equipped with a hydro-acoustic communication system with SPNs throughout its ongoing sailing along the SPNs deployment lines. Thereafter acquired data are processed. | 05-31-2012 |
