Abstract:
1. A method for deghosting seismic data related to a subsurface of a body of water, the method comprising: receiving data recorded with seismic detectors that are towed by a vessel, the data being associated with waves travelling from the subsurface to the seismic detectors; applying with a processing apparatus a migration procedure to the data to determine a first image of the subsurface; applying with the processing apparatus a mirror migration procedure to the data to determine a second image of the subsurface; joint deconvoluting with the processing apparatus the first image and the second image for deghosting a reflectivity of the subsurface; and generating with the processing apparatus a final image of the subsurface based on the deghosted reflectivity of the joint deconvoluting step.
