Seismic source cluster for marine seismic exploration
A recently granted patent (Publication Number: US11988788B2) discloses a cluster of seismic sources designed for marine seismic exploration. The cluster comprises a ring-shaped bracket capable of holding between three to twelve seismic sources. The bracket includes a hub, an outer frame, and spokes connecting the hub to the outer frame. The seismic sources, when attached to the bracket, are fixedly positioned to point perpendicular to the plane defined by the spokes. Additionally, the seismic sources are equidistant from the center point of the bracket, ensuring uniform distribution.
Furthermore, the patent details the configuration of the seismic sources in a circular pattern of outlet ports, allowing the signal output bubble to coalesce when firing, similar to the output signal from a single seismic source. The firing chambers of the seismic sources are supported by the ring-shaped bracket, which also includes provisions for air and electrical conduits. The patent also describes the operation of the seismic sources using a firing sequence, enabling different seismic sources within the cluster to fire at various points in time with preset patterns. Overall, the patented cluster of seismic sources offers a novel and efficient solution for marine seismic exploration, enhancing data collection capabilities in underwater environments.
