Abstract: Techniques are disclosed relating to geophysical surveying. In various embodiments, a computer system may access seismic data for a geological formation, where the seismic data is recorded, using one or more sensors, during a seismic survey in which a first vibratory source was driven using a first digital code for at least a first time interval. The first digital code, in some embodiments, may include a first plurality of subsections corresponding to portions of the first time interval. In some embodiments, the computer system may image a first location of the geological formation using a correlation of only a first sub-section of the first plurality of sub-sections with the seismic data. Further, in some embodiments, the computer system may image a second location of the geological formation using a correlation of two or more of the first plurality of sub-sections with the seismic data.

Abstract: Embodiments may be directed to marine vibrators and associated methods that use appropriately selected composite code sequences. A method of seismic surveying may comprise operating a plurality of marine vibrators. At least one of the marine vibrators may repeatedly cycle through a plurality of composite code sequences that are unique to the at least one of the marine vibrators, wherein two or more of the marine vibrators operate contemporaneously for at least one output interval. The method may further comprise detecting seismic energy with one or more seismic sensors after the seismic energy has interacted with subsurface formations, wherein the seismic energy was emitted from the marine vibrators, wherein the detecting occurs while operating the plurality of marine vibrators.

Abstract: A plurality of sensors and a controller are disposed in a marine seismic streamer. Each of the sensors comprises an enclosure having two opposing interior walls, first and second piezoelectric elements disposed on the opposing interior walls, a third piezoelectric element disposed on a flexible substrate within the enclosure between the opposing interior walls, a pressure signal output node and an acceleration signal output node disposed on the exterior surface of the enclosure. A combined pressure signal derived from the pressure signal output nodes of the plural sensors is coupled to a pressure signal input of the controller. A combined acceleration signal derived from the acceleration signal output nodes of the plural sensors is coupled to an acceleration signal input of the controller. The streamer may be towed, and the combined pressure and acceleration signals may be recorded in a computer-readable medium.
