Abstract
A seismic data acquisition system is configured to collect seismic data. The system includes a marine source array configured to be attached to a fixed structure floating at the water surface and including vibratory source elements; and a controller configured to control the vibratory source elements so that a beam formed by the source array is steerable.
Claims20
A seismic data acquisition system for collecting seismic data, the system comprising:
- a marine source array configured to be attached to a fixed structure floating at the water surface and including vibratory source elements;
- and
- a controller configured to control the vibratory source elements so that a beam formed by the source array is steerable.
A marine source array for generating seismic energy, the source array comprising:
- plural vibratory source elements permanently attached to a fixed structure substantially stationary in water;
- and
- a controller configured to control the vibratory source elements so that a beam formed by the source array is steerable.
A method for illuminating a weak underwater target, the method comprising:
- suspending a source array from a fixed structure that is substantially stationary in water during a seismic survey;
- downloading in a controller of the source array a first sweep signal;
- applying the first sweep signal to the source array to generate a beam having a first direction;
- and
- emitting the beam toward a subsurface of interest.
