Paper Number: SEG-2022-3746892
... Seismic field data suffer from Low Resolution (LR) image quality. This is due to the limited number of sensors used in a given seismic survey, as well as physical and technological limitations of the sensors. To obtain high-resolution (HR) images, either higher density acquisitions are carried...
