Patent ID: 8456951

Claim:
A method for deghosting seismic data related to a subsurface of a body of water, the method comprising: recording, with detectors, seismic waves traveling from the subsurface, wherein the detectors are located on a streamer having birds that are controlled to achieve a curved portion of the streamer; inputting data recorded by the detectors that are towed by a vessel, the data being associated with the waves travelling from the subsurface to the detectors; applying a migration procedure to the data to determine a first image of the subsurface; applying a mirror migration procedure to the data to determine a second image of the subsurface; joint deconvoluting the first image and the second image for deghosting a reflectivity of the subsurface; and generating a final image of the subsurface based on the deghosted reflectivity of the joint deconvoluting step.
