Abstract

A practical method to determine time-distance rules for efficient Vibroseis acquisition

Since its development by Conoco in the mid-1950s Vibroseis has become the predominant source for onshore seismic surveys. Coupled with its increase in popularity has been a need to increase its productivity. Over the years a number of acquisition techniques have been introduced, culminating in the ISS/blended/unconstrained acquisition technique where no restrictions are placed on when sweeps can be initiated. This, unfortunately, can result in unacceptable levels of noise contamination. A more optimum solution, therefore, which balances productivity and noise contamination, is to apply a set of slip-time/distance separation rules. In this paper we have shown how to acquire and analyse test data that allow such rules to be defined in the most efficient manner.
