Method and marine acoustic source array for generating an acoustic wave in a body of water. The marine acoustic source array includes a first depth sub-array set of first acoustic source points configured to be provided at a first depth (z), the first acoustic source points having different inline first locations along a longitudinal axis (X); and a second depth sub-array set of second acoustic source points configured to be provided at a second depth (z), the second acoustic source points having different inline second locations along the longitudinal axis (X). The first locations do not coincide along the longitudinal axis (X) with any of the second locations.

Compact broadband source and method

Method and marine acoustic source array for generating an acoustic wave in a body of water. The marine acoustic source array includes at least one sub-array. The at least one sub-array includes a float from which plural source points are attached. The source points may be provided on a curved line, straight line, or other desired shape so that a variable-depth source is obtained with a single float. The source points may be divided into groups and the groups may be provided on the curved line, straight line or other desired shape.

Variable-depth seismic source and method

Method and dynamically-adjusted marine acoustic source array for generating an acoustic wave in a body of water. The acoustic source array includes a float; plural actuation devices, each actuation device having corresponding cables; and plural source points connected to the float through the corresponding cables. The plural actuation devices dynamically adjust corresponding lengths of the corresponding cables to achieve a desired variable-depth profile for the plural source points.

Dynamically-adjusted variable-depth seismic source and method

The invention relates to a source device for the emission of seismic waves designed to operate by being towed by a vessel. The source device according to the invention comprises at least three support-beams, a plurality of guns placed along each support-beam, a central hub receiving one end of support-beams and arranged such that support-beams can be deployed according to a star-like geometry, and the means to keep support-beams in this geometry during operation.

Foldable marine seismic source

The invention concerns a device for emitting seismic waves designed to operate by being towed by a vessel, characterized in that it comprises means capable of discharging compressed air under high pressure into water, to generate a bubble () of a general annular shape.
