Sweeping changes for Vibroseis operations

Abstract

This paper reviews current slip-sweep and High Fidelity Vibratory Seismic (HFVS) operations and tracks their evolution over the past 3-5 years. Projecting the technological advances and operational experience over this period, high-productivity and high-resolution vibroseis surveys may become a future standard in the oil industry. Such surveys utilising simultaneous sweep technology are designed to use increased vibroseis production to explore large areas with suitable fold and resolution, or improved seismic data quality through increased fold and denser surface sampling. Further improvement in seismic data quality in all forms of vibroseis acquisition is achievable by real-time processing of actual vibrator ground motion with the uncorrelated field record. Perhaps vibroseis signal correlation with a synthetic pilot sweep will become anoutdated standard?
