A method of and a device for processing recorded seismic data

Abstract

A method of processing recorded seismic data is disclosed. The recorded seismic data os obtained in response to an acoustic signal transmitted using a transducer of a parametric sub-bottom profiling system, a wave shape of the transmitted acoustic signal varies as a function of water depth. The method is performed by a processor and comprises the steps of: determining a plurality of source signatures of the transmitted acoustic signal respectively for a plurality of adjacent water depth ranges, where each water depth range being smaller than a range threshold; deriving a unit-impulse response for each one of the water depth ranges by deconvolving the source signature of the seismic signal at that water depth range; generating a model representing relationship between the source signature of the transmitted acoustic signal at each water depth range and that water depth range based on the derived unit-impulse response for all the water depth ranges; and processing the recorded seismic data by applying the model to the recording seismic data. Unlocking insights from Geo-Data, the present invention further relates to improvements in sustainability and environmental developments: together we create a safe and liveable world.
