Technical Abstract
Primary-preserving multiple attenuation for broadband data
Back to Technical ContentMultiple attenuation is a key step of broadband marine processing which could be challenging for primary preservation, spatial continuities and low frequencies. Rather than a cascaded de-multiple sequence, which could lead to cumulate mistakes and uncertainties, with final results potentially questionable for further pre-stack inversion, we propose an optimized multiple attenuation methodology, as well as new Quality Control tools based on correlations and pseudo-Impedance.
