Abstract. The article describes advantages of bottom cable seismic systems utilization for monitoring of offshore oil & gas deposits exploitation dynamics and compares different types of seismic sensors used for offshore seismic data harvesting. It is emphasized, that such systems are offered by service companies as a part of expensive high-tech monitoring services, which are not available for Russian oil & gas companies due to implemented economic sanctions. The authors make a conclusion about necessity of domestic seismic monitoring system development.

The article shows existing experience of Russian engineers from MIPT Scientific and Technology Center of Marine Geophysics in development of domestic seismic monitoring system based on ocean bottom cables. The cables are equipped with state-of-the-art technology invented and developed by MIPT specialists – high sensitive wide range molecularly-electronic seismic sensors. A new power transmission technology using fiber optics – “Power-over-Fiber” is also described. Authors made a prospect of changing the technological approach in development of seismic recording systems in respect of fiber optics utilization and determine the main areas for further R&D projects.

Keywords: 4D seismic, field monitoring, molecular electronic sensors, fiber optic technology.
