Improved signal processing for sub-basalt imaging
Year: 2014
Type: article
Abstract: Sub-basalt imaging continues to provide a challenge within the West of Shetland region. Successful imaging is being achieved through the reprocessing of 2D reflection seismic data. These were acquired with conventional source array and streamer parameters and include key signal processing techniques. The first technique involves spectral processing to boost low-frequency signals at the early stages of processing. The second technique involves attenuating coherent and incoherent noise in all of the available ‘time-offset’ domains. Examples of the data after application of these techniques are presented and clear improvements over the original processing are demonstrated. As work on these reprocessing methods has progressed, the benefits of moving to a true broadband processing solution have become clear.
