摘要： The present invention relates to seismic exploration techniques and the seismic imaging of subsurface layers, particularly apparatus for seismic exploration near the seafloor. The apparatus enables controlled-depth towing of detectors to be carried out a short distance above the seafloor. The apparatus includes a streamer depth controller and at least one altitude keeper device, attached at intervals along the length of a towed streamer. The streamer carries detectors for measuring, for example, P- and S-waves in the seafloor.

摘要： A method of conducting a marine seismic survey of a survey area which comprises deploying a plurality of receiver cables (11) to define an active receiver area (12) the cables (11) extending in a longitudinal direction and towing a seismic source (14) behind a source vessel (13) to track across the active receiver area (12) in the longitudinal direction along a first line, turning the source vessel (13) and its source (14) around and then towing the source (14) to track back across the receiver area (12) in the reverse longitudinal direction along a second line, generally parallel to the first line. The second line is spaced from the first line in a transverse direction which is generally perpendicular to the longitudinal direction. The tracking, turning and tracking back steps are then repeated whereby the source vessel (13) and its source track across the active receiver area (12) along successively advanced lines. The source (14) is continuously fired at particular positions and/or time intervals while it is tracking the receiver area (12), and the seismic responses to the firing are continuously detected using the deployed receiver cables (11). The receivers (11) are picked up while the source (13) is being fired and redeployed.

摘要： A method of assessing acquisition errors in seismic images in a seismic data volume. The method comprises selecting a seismic attribute in a seismic data volume and then stacking seismic quality image measurement taken along the selected attribute. The stacked measurements are then related on the basis of any vertical correlation and any vertically correlated feature is identified as a cobweb. Any identified cobwebs are removed from the seismic data volume.

摘要： Systems for the acquisition of seismic data. In one embodiment, a daughter vessel (11) tows a wide source (13) and an array (14) of short receiver streamers (22), while a mother vessel (12) tows a second array (15) of long receiver streamers (26). An initial survey is carried out, and multiples in the response data are filtered out. Then a second acquisition regime is carried out and the results combined with the initial survey to eliminate shadows.
