Title: NOISE REMOVAL IN NON-UNIFORMLY SPACED SEISMIC RECEIVER ARRAYS
Abstract:
Embodiments of non-uniformly spaced seismic receiver arrays and associated noise removal techniques are disclosed. In one embodiment of a method of seismic data acquisition, a plurality of seismic receivers (105) may be positioned in an array (110a) having a plurality of regions (115a, 120a, 125a, 130a, 135a), each region (115a, 120a, 125a, 130a, 135a) in the array (110a) having a respective average spacing between seismic receivers (105), with the average spacing in a second region (120a) of the plurality of regions (115a, 120a, 125a, 130a, 135a) being greater than the average spacing in a first region (115a) of the plurality of regions (115a, 120a, 125a, 130a, 135a) that is adjacent to the second region (120a). Seismic data may be acquired utilizing the plurality of seismic receivers (105), and noise may be removed therefrom.
