“…With these improvements, slip‐sweep has been freed from previous constraints (memory, radio frequency availability and range). In North Africa, surveys with 12 fleets of single vibrators using long sweeps (e.g., 40 s) but a short slip‐time (e.g., 5 s) were performed with production above 700 VP's/hour providing much denser spatial sampling on the source side (Meunier, Bianchi and Ragab 2007; Meunier et al . 2008).…”

Capitalizing on the very long spreads laid out in desert areas (more than 20 km-long receiver lines), BP prompted the simultaneous use of widely separated flip-flop or slip-sweep fleets with their DSSS methodology, which depending on the number of vibrator groups theoretically doubles or triples productivity (Bouska 2008(Bouska , 2009(Bouska , 2010.…”

The development of high‐productivity seismic recording using the vibroseis method over the last 30 years is treated from a Sercel perspective. The simultaneous use of vibrators has been highly dependent on real‐time field computing capabilities such as those delivered by the correlator‐stackers in the early 1980s. A second step forward in the mid 1980s–early 1990s was related to digital vibrator electronics, which provides efficient management and quality control of fleets of vibrators. However, it was only in the late 1990s with the advent of real‐time satellite positioning (GPS) of these fleets that alternate or simultaneous sweeping was commonly used in production. During the last ten years, thanks to GPS timing, continuous data recording and innovative simultaneous sourcing methodologies, vibroseis has been able to reach unexpected levels of productivity. As a result, the cost per seismic trace has dropped, enabling denser spatial sampling and associated seismic imaging improvement.

“…Slip-sweep and HPVA demonstrate how vibroseis acquisition can be made more efficient. The next step to consider is reducing the source array size, so we reduced the fleet to a single unit and introduced V1 single vibrator acquisition (Meunier et al, 2007). V1 acquisition comprises a larger number of smaller fleets of vibrators covering a dense grid of shotpoints and provides the next step-change in source productivity.…”
