In marine seismic data acquisition, de-blending multiple simultaneous sources is a challenging, undetermined problem and sparsity constraints are often used to derive a stable solution. In this article, we discuss the impact of additional adaptive co

Summary We introduce a stable and robust approach for QRTM by compensating seismic data for the effects of anelastic loss. Our approach is based on computing matching filters between attenuated and non-attenuated data in the shot domain. The filters

Source designature for seismic data acquired using an air-gun array aims to remove the effects of pulse asymmetry, bubble oscillation, array directivity, and ghosting at the sea surface. For the process to be successful, we require an accurate repres

Summary This paper presents the acquisition and processing of a field test of triple-source streamer apparition, a blending technique for marine airgun sources that uses periodic codes in contrast with the more commonly used natural or artificial ran

Summary De-signature processing of broadband seismic data demands reliable signature estimation in the band 2–200 Hz. Here we discuss estimation of signatures via inversion of near-field hydrophone data. This uses a model for the propagation of ene

Summary In Ocean Bottom Multicomponent acquisitions, the particle motion recordings can be heavily contaminated with shear-wave noise. The presence of this shear-wave noise, especially on the Z-component, hinders the preprocessing steps required to a
