It has been shown that reducing the source line interval can significantly improve the acquisition footprint of land data. To achieve this reduction without impacting acquisition rates requires the use of high-productivity techniques such as slip-sweep and ISS, typically utilising single vibrators with extended sweeps. These techniques result in a decrease in shot record quality as the sweeps from different vibrators overlap. This paper discusses an altogether more tractable solution: vibrator groups with short sweeps. High productivity can be achieved without interference between different sweeps.
