Patent ID: 8467264

Claim:
A method to acquire near-zero offset survey data, comprising: towing, by a first marine vessel, a first survey source and a first streamer attached to the first survey source, wherein the first streamer has at least one survey receiver, and wherein the at least one survey receiver is in-line with the first survey source; towing, by the first marine vessel, a second streamer that has survey receivers, the second streamer separate from the first survey source and first streamer, wherein the first survey source is spaced apart, in an in-line direction, from a closest survey receiver of the second streamer by a first distance, and wherein the first survey source is spaced apart, in the in-line direction, from the at least one survey receiver of the first streamer by a second distance less than the first distance; measuring near-zero offset data using the at least one survey receiver of the first streamer; providing a second survey source and a third streamer attached to the second survey source, the third streamer having at least one survey receiver, and wherein the at least one survey receiver of the third streamer is in-line with the second survey source such that no cross-line gap exists between the at least one survey receiver of the third streamer and the second survey source, and wherein the second survey source and the third streamer are spaced apart in a cross-line direction from the first survey source and the first streamer; measuring near-zero offset data using the at least one survey receiver of the third streamer; and measuring cross-line data wherein the at least one survey receiver of the third streamer measures signaling produced by the first survey source.
