Abstract
A seismic cable (1) including a plurality of electrical/optical elements (5) which are arranged to be interconnected with a number of seismic sensor devices (24) arranged at intervals along the cable and installed in a housing (15) integrated in the cable (1). The sensor housing (15) is centrally arranged in the cable (1) and interconnected with a central strength element (2). The electrical/optical elements (5) are arranged over and around the central element (2) and over the housing (15).
Claims7
A seismic cable including a plurality of electrical/optical elements which are arranged to be interconnected with a number of seismic sensor devices arranged at intervals along the cable, the sensor devices being installed in a housing integrated in the cable, wherein the sensor housing is interconnected with a central strength element and the sensors are disposed in a cylindrical cavity which is symmetrical relative to the central element, the electrical/optical elements being arranged over the housing in an expanded configuration shape.
A method for making a seismic cable including a plurality of electrical/optical elements which are arranged to be interconnected with a number of seismic sensor devices, arranged at intervals along the cable, characterized by arranging the sensor devices inside a housing which is centrally located in said cable such that said elements pass radially outwardly of said housing, and providing interconnections between the sensor devices and the elements externally of the housing via at least one bore in the wall of the housing.
