Abstract
A seismic source using tuned pulse sources to form an ultra-low frequency (ULF) cluster intended for use in generating seismic energy impulses for marine seismic exploration and more specifically to improved performance by increasing low frequency output to within a range of 1 Hz to 3 Hz to provide greater penetration of the seismic signal through complex overburden such as salt or basalt.
Claims20
A cluster of seismic sources for marine seismic exploration, comprising:
- a ring-shaped bracket configured to hold more than three seismic sources and hold up to twelve seismic sources, the ring-shaped bracket including:
- a hub,
- an outer frame configured to hold the seismic sources, the outer frame being located around the hub, and
- plural spokes extending in a plane and connecting the hub to the outer frame,
- wherein the plural spokes are fixedly connected to the hub so that the seismic sources, when attached to the ring-shaped bracket, permanently point perpendicular to the plane.

A cluster of seismic sources for marine seismic exploration, comprising:
- a ring-shaped bracket configured to hold more than three seismic sources and hold up to twelve seismic sources, the ring-shaped bracket including, a center hub;
- spokes affixed to the center hub;
- an outer frame affixed to the spokes;
- a support for the seismic sources affixed to the outer frame;
- and
- a clamp removable from the support to secure the seismic sources to the support.
3 more elements
A cluster of seismic sources for marine seismic exploration, comprising:
- a ring-shaped bracket configured to hold more than three seismic sources and hold up to twelve seismic sources;
- and
- plural seismic sources attached to the ring-shaped bracket,
- wherein the seismic sources are operated by using a firing sequence to have all or some of the seismic sources within the cluster fire at different points in time.
