Vibroseis is the most popular source for land seismic acquisition, being used whenever accessis possible due to its repeatability, controllable bandwidth, and low-cost. Despite the increasingpopularity of 3D surveys, 2D surveys continue to be acquired. Over the last 30 years several highproductivityVibroseis techniques have been introduced for 3D surveys, many enabled by thewidespread adoption of nodal acquisition systems, but there is little evidence of their adoptionfor 2D surveys. In this paper I show how the use of a combination of the employment of a nodalacquisition system and a distanced separated acquisition technique increased productivity by61% over flip-flop and 118% over single-vibrator acquisition, with no detrimental effects on dataquality. In the future I anticipate that the employment of such techniques will be routine, particularlygiven that there is potential to increase productivity even further through the employmentof additional vibrators.
