Abstract

Fiber optic sensor systems have been under development for many years. We have produced prototype seismic equipment to demonstrate the optical technology. 4C seabed systems, streamers and near field airgun recording are a few of the projects under development. A 4C seabed cable has been successfully demonstrated during field operations in the North Sea. Data collected from the field tests have proven the prototype optical system meets the performance required of the deepwater seismic operation. It is an excellent fit for conventional 4C seismic operations and would also be the preferred solution for permanently installed reservoir monitoring systems. Some of the advantages we expect to realize from an optical system include: no in-sea electronics, improved reliability, lighter weight, significantly reduced deployed system cost and improved operational safety.
