摘要
The disclosure provides a borehole tool for seismic data collection. The tool comprises a cable to be positioned within a borehole and at least one sensor for measuring seismic signals mounted on the cable. The sensors provide measurements of particle motion (velocity or acceleration) perpendicular to an axis of the borehole. The disclosure also provides methods of seismic surveying, which involves positioning the tool in the borehole, firing a seismic source generating a seismic wave and measuring particle motion associated with the passing seismic wave perpendicular to an axis of the borehole using the at least one sensor for measuring particle motion.
