Abstract
A marine seismic acquisition method capable of obtaining low frequency marine seismic data. The method can employ a dipole capable of reducing interference from waves reflected from the surface of a body of water for low frequency subsurface measurements. The dipole can be deployed from a surface vessel with a plate, drivers, and springs to generate a low frequency resonance.
Claims20
A marine dipole source comprising:
- a moveable plate connected to a surface vessel by a deployable structure;
- one or more drivers configured to oscillate the moveable plate;
- and
- one or more spring elements connected to the moveable plate configured to generate resonance in a frequency band of interest.
1 more element
A method of marine seismic surveying, the method comprising:
- connecting a seismic dipole source to a surface vessel;
- moving the surface vessel through a body of water over an undersea formation;
- generating low frequency seismic signals by the seismic dipole source;
- and
- receiving reflected low frequency seismic signals by a plurality of sensor streamers.
2 more elements
A marine seismic surveying system comprising:
- a moveable surface vessel;
- a marine dipole source connected to the moveable surface vessel;
- a control system for the marine dipole source on the moveable surface vessel;
- and
- at least one sensor configured to receive acoustic energy generated by the marine dipole source.
