Abstract
Abstract A method of acquiring seismic data is disclosed which includes a horizontal towed receiver array in conjunction with at least one vertically oriented receiver array formed from a plurality of receiver elements spaced apart vertically within a plurality of cable. By simultaneously recording the data from both arrays, seismic data can be acquired for locations directly beneath a fixed obstruction, which a towing vessel has had to steer around.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
A method of surface seismic exploration in a marine environment having fixed obstructions to the collection of seismic data in a region of interest, comprising: (a) suspending at least one vertical receiver array in the water adjacent the obstructions; (b) towing a linear, horizontal receiver array along a generally linear track in proximity to the obstruction; and (c) initiating seismic source elements towed along the linear track and simultaneously recording the resulting seismic signals from the at least one vertical receiver array and the linear, horizontal receiver array.
Claim 2
Independent Claim
88 words
A method of surface seismic exploration in a marine environment having fixed obstructions to the collection of seismic data in a region of interest, comprising: (a) suspending at least one vertical receiver array in the water adjacent the obstructions; (b) towing a linear, horizontal receiver array along a generally linear track in proximity to the obstruction; and (c) initiating seismic source elements towed along the linear track and simultaneously recording the resulting seismic signals from the at least one vertical receiver array and the linear, horizontal receiver array.
Claim 3
Dependent Claim
18 words
The method of claim 1 wherein the at least one vertical receiver array is suspended from the obstruction.
Claim 4
Dependent Claim
28 words
The method of claim 1 wherein the at least one vertical receiver array comprises a plurality of suspended vertical receiver arrays aligned in proximity to the linear track.
