Abstract
Summary
This paper show how new insight into seismic interference (SI) and cross-party coordination has eliminated the need to timesharing in the North Sea. With this new approach seismic vessels were in 2016 also allowed to operate as close at ∼7km apart while acquiring seismic data. This stands in contrast to previous accepted guidelines stating that vessels should stay at least 40km. The end of timesharing and the added flexibility provided by allowing vessels to operate in close proximity represents a significant increase in acquisition efficiency, which also translates into cost savings.
The presented approach for SI-management can easily be adapted and applied in other areas.
