Abstract

Summary

In this presentation a new single station rotational seismic sensor is introduced. The new sensor enables simultaneous rotational and translational sensing in three orthogonal axes, representing 6 component (or 6C) measurements.

Data examples and early results from an offshore field trial are presented, where the new sensor has been deployed in an ocean bottom node (OBN). Data from the new sensor are compared to reference data from adjacent conventional ocean bottom nodes containing standard 3C geophones.

Our findings are that the new sensor is fully deployable in an OBN setting and provides results consistent with reference data obtained by conventional nodes. These capabilities in a single station sensor also means there is potential for significant efficiency gains in OBN acquisition.
