Abstract
Summary
Early on in the history of seismic acquisition the advantages of being able to acquire data without the impediment of cables was identified. Despite the introduction of numerous systems since the 1970s nodal land acquisition systems have only relatively recently become popular. We begin this paper by looking at the history of nodal land seismic acquisition systems. We then look at the rapid developments that have occurred over the last 10 years, including reductions in weight, increases in recording duration, and the increasing popularity of integrated systems. The question of which nodal system to use depends to a large extent on the survey location and requirements. Overall, we see a trend towards using larger numbers of lighter nodes.
