Node Hub – a seismic reservoir monitoring system for deployment on the seafloor in marine seismic surveys, and a method for deployment of seismic sensor nodes on the seafloor and collecting the seismic sensor nodes.

摘要

A sensor system for deployment on the seafloor in marine seismic surveys includes a hub, a seismic base station on the hub, and a plurality of seismic sensor nodes that are mounted outside of the seismic base station in base units. The system further includes recording electronics, a memory for storing seismic data and a battery for providing power for an extended period in the surveys. Further, a method of deploying a sensor system on the seafloor by an ROV, the seismic sensor nodes are detached from the seismic base station by the ROV's manipulator arm and positioned at their respective recording positions.
