Abstract: High-productivity vibroseis techniques have been developing rapidly and been applied widely in the Middle East and Africa in pursuit of high productivity. This paper briefly reviewed the high-productivity vibroseis techniques such as Slip Sweep, Distance Separated Simultaneous Sweeping (DSSS), DSSS plus Slip Sweep, and Independent Simultaneous Sweeping (ISS), introduced key techniques developed by BGP, including geometry design, non-stake surveying, quality control, and harmonic attenuation, and finally presented the application effects of the techniques in seismic projects of BGP International.

Key words: high-productivity vibroseis, slip sweep, DSSS plus slip sweep, independent simultaneous sweeping (ISS), harmonic attenuation, non-stake surveying
