We are also a leading engineering and solution provider and can offer a suite of distributed optical
fiber sensors (DOFS), interrogators for a wide range of applications. Its instruments measuring
temperature, strain and dynamic strain (i.e. vibration or seismic signals) in one box, are world leading.
Its experience includes the integration of its interrogators in harsh environment including subsea.

FOSINA’s interrogator is designed to cover many applications within O&G industry including but not
limited to:

• Pipeline monitoring including third party intrusion and leak detection
• Seismic monitoring including real time source synchronization to allow correlation and stacking.
• Frac monitoring
• Injection monitoring
• Production monitoring
• Integrity monitoring
• Casing shearing monitoring
• Microseismic monitoring

Above applications are also possible in subsea environment thanks to our unique extended range
module that enables us to preserve best SNR with 100+km of umbilical length.
