Abstract
Permanent seismic installations at the sea-floor have emerged as a potential tool for oil companies in their work to actively monitor oil/gas flows and injection processes in order to increase hydrocarbon recovery and optimize production. The passive nature of fibre-optic sensors, embedded into 4C receiver station, is an advantage since the in-sea sensor equipment is not prone to electrical noise, leakage and short circuit, in addition to that the life-time of the buried sensors may be longer compared to electrical systems. Fibre-optic based permanent seismic monitoring systems represent a great opportunity for the field engineers, in a cost effective way, to optimize production and increase the hydrocarbon recovery rate from existing fields.
