Abstract: A system for performing seismic surveys may include devices to attach fiber-optic cables and/or sensors to existing subsea infrastructure, as well as devices for recording seismic data at the fiber-optic cables/sensors attached to or incorporated within existing infrastructure. A method for seismic imaging of a subsurface volume of interest may include recording seismic data using fiber-optic cables attached to existing subsea infrastructure, processing the seismic data to create processed seismic data, and generating seismic images/attributes of the subsurface volume of interest from the processed seismic data. Additionally, the invention includes a one-way ranging technique to determine the location of FO cables using an integrated dynamic monitoring system and FO cables/sensors. The methods may be executed by a computer system.
