Abstract
Poor knowledge of source and receiver positions in ultra-high-resolution marine seismic data is the cause of severe damage which requires novel processing techniques to mitigate. Current positioning technologies are limited partly by their accuracy but also the fact that they are only placed on head and tail buoys of the towed arrays. This leaves receiver locations on the length of the streamer cable to be interpolated. Rather than developing additional processing methods, we propose to improve the quality of the data by introducing a complimentary receiver positioning system to reconstruct the shape of the streamer cable in 3D using Fiber Optic Shape Sensing (FOSS) technology. In this abstract, we present the methods and hardware of this method as well as our progress in the development of experiments designed to establish the viability of FOSS in the field.
