Technical Abstract

Source deghosting for synchronized multi-level source streamer data

Back to Technical Content
Ghost wavefield elimination is pivotal for improving the bandwidth and image resolution for marine seismic data. Synhronized multi-level source arrays, which aim to synchronize the primary wavefield and desynchronize the source ghost, can greatly attenuate the source ghost wavefield during acquistion. However, even with this advanced source design, some source deghosting is still needed and can be achieved using a 3D joint source inversion algorithm. We demonstrate that the joint source inversion method can properly and effectively eliminate residual source ghost in the synchronized multi-level source streamer data using both 2D synthetic data and 3D real data examples.
