Slip Sweep Seismic Acquisition Operations. Origin of Nonlinear Distortions and Noise Suppression Technique

Abstract

Summary Bashneftegeofizika JSC fulfilled Slip Sweep seismic acquisitions of 56 sq.km (45408 SP) in 2017 on Respublic of Bashkortostan area with 5 single NOMAD-65 vibrators. Analysis of vibrorecords and correlograms field data allowed to understand the nature of origin and supression technique for the noise wich is typical for all methods where sweep overlap in time presents.
