Technical Abstract

Wave height guided multi-shot receiver deghosting

Back to Technical Content
Free-surface datum variations cause complications for hydrophone only receiver deghosting algorithms that assume a horizontal free-surface. We describe a multi-shot receiver deghosting approach that derives a tau-psht-prec model of ghost free data at mean free-surface datum. The model is derived so as to simultaneously satisfy the recorded primary and ghost wavefields in the presence of a non-horizontal free-surface at the source and receiver sides. The approach is shown to produce high resolution receiver deghosting results with improved spatial consistency on a broadband variable depth streamer dataset from the North Sea.
