PRM Systems: Permanent Reservoir Monitoring

PRODUCT DETAILS

Data collected by our permanent and retrievable seafloor and wellbore seismic solutions allows oil and gas engineers to actively monitor critical changes inside the reservoir. Through our energy exploration technology’s acquisition of more and better data, engineers dramatically enhance their operational and production decisions over the life of the reservoir.
