Abstract
Methods and apparatus for reducing the impact of guided (or 'tube') waves in permanently installed seismic systems are provided. By utilizing passive acoustic absorbers, the impact of tube waves may be reduced, leading to improved performance of permanently installed seismic systems that are installed onto production tubing when the well is completed.
