(2016) Meeting 2016 - Society of Exploration Geophysicists 35. p.71-76- Abstract
Marine seismic data are distorted by ghosts as waves propagating upwards reflect downwards from the sea surface. Ghosts appear both on the source-side as well as on the receiver-side. However, whereas the receiver-side ghost problem has been studied in detail and many different solutions have been proposed and implemented commercially, the source-side ghost problem has remained largely "unsolved" with few satisfactory commercial solutions available. In this paper we propose a radically new and simple method to remove sea-surface ghosts that relies on using sources at different depths but not at the same lateral positions. The new method promises to be particularly suitable for 3D applications on sparse or incomplete acquisition... (More)
