Abstract
The acquisition of n-shots, more or less simultaneously, increases acquisition efficiency and collects a wider range of information for imaging and reservoir characterisation. Its success relies critically on the ability to separate n-shots from one recording. Using a difficult data example we show that a PEF-based adaptive subtraction of the estimated wavefield due to a secondary source provides an effective separation of the sources.
