Abstract

A staggered vertical marine seismic source contains upper and lower arrays (10, 11) of emitters of seismic energy (S11, S12; S21, S22). The upper array (10) is horizontally displaced relative to the lower array (11). The source is used in a marine seismic surveying arrangement that has means for moving the source and at least one seismic receiver. In use, the source is moved through the water in a direction parallel to the direction in which the two arrays are displaced. The arrays (10, 11) are fired sequentially, and the time delay between the firing of the first-fired array and firing of the second-fired array is chosen such that each seismic emitter in one array is fired at the same x-and y-coordinates as the corresponding emitter in the other array. The seismic wavefields generated by firing the two arrays are thus generated at the same x- and y co-ordinates, but at different depths. The seismic data recorded at the receiver(s) as a consequence of firing the first array can be used to de-ghost the seismic data acquired as a result of firing the second array or vice-versa, thereby eliminating or reducing the effect of source-side ghost reflections and reverberations.

Description

(57) A staggered vertical marine seismic source contains upper and lower
arrays (10, 11) of emitters of seismic energy (S11, S12; S21, S22). The upper array (10) is horizontally displaced relative to the lower array (11). The source is used in a marine seismic surveying arrangement that has means for moving the source and at least one seismic receiver. In use, the source is moved through the water in a direction parallel to the direction in which the two arrays are displaced. The arrays (10, 11) are fired sequentially, and the time delay between the firing of the firstfired array and firing of the second-fired array is chosen such that each seismic emitter in one array is fired at the same x-and y-coordinates as the corresponding emitter in the other array.
The seismic wavefields generated by firing the two arrays are thus generated at the same x- and y
co-ordinates, but at different depths. The seismic data recorded at the receiverts) as a consequence of firing the first array can be used to deghost the seismic data acquired as a result of firing the second array or vice-versa, thereby eliminating or reducing the effect of source-side ghost reflections and reverberations.
