Why Fiber Optic Well Monitoring Matters

Passive distributed sensing for harsh, long-distance and unattended well environments

Oil and gas well monitoring often requires long-distance sensing, high environmental adaptability and continuous online data. Distributed fiber optic sensing turns the fiber cable into the sensor, enabling acoustic, vibration and temperature monitoring over long distances.

01

Passive Sensing Cable

The sensing fiber requires no power along the cable, making it suitable for long-distance well and field monitoring.

02

No Blind Spots

Distributed measurement helps monitor every point along the fiber instead of relying only on isolated point sensors.

03

Acoustic + Temperature

DAS detects vibration and acoustic events, while DTS monitors temperature changes and thermal anomalies.

04

Remote Operation

Online monitoring and remote access support unattended operation and reduce the need for frequent field inspections.

DAS + DTS Monitoring Principle

Rayleigh sensing for vibration, Raman sensing for temperature

DAS and DTS use different optical scattering mechanisms to extract different physical information from the same fiber-based monitoring concept.

Two distributed sensing technologies, one well monitoring strategy.

DAS FS-5100 focuses on acoustic and vibration events. DTS-1000B focuses on distributed temperature profiles. Used together, they provide a more complete picture of well activity, safety status and abnormal events.

DAS is suitable for event detection and localization. DTS is suitable for temperature curve monitoring and thermal anomaly localization.
DAS FS-5100

Coherent Rayleigh Scattering

Vibration and acoustic disturbances change the backscattered optical signal. The system analyzes these changes to detect, recognize and locate vibration events along the fiber.

DTS-1000B

Raman Scattering

Temperature changes affect Raman backscattering. The system calculates temperature distribution along the fiber and locates abnormal thermal changes.

OTDR

Optical Time-domain Location

Return time of optical signals is used to map acoustic or temperature changes to specific positions along the sensing fiber.

Platform

Online Monitoring

Monitoring data can be displayed, analyzed and accessed remotely for unattended operation and maintenance planning.

FAQ

Distributed Fiber Optic Well Monitoring FAQ

Common questions about combining DAS FS-5100 and DTS-1000B for oil and gas well acoustic, vibration and temperature monitoring.

Why put DAS FS-5100 and DTS-1000B on one page?
They are complementary distributed fiber optic sensing systems for well monitoring. DAS FS-5100 monitors acoustic and vibration events, while DTS-1000B monitors temperature distribution. A combined solution page helps customers understand how both systems support oil and gas well safety monitoring.
What is the difference between DAS and DTS?
DAS focuses on acoustic and vibration event detection using Rayleigh scattering. DTS focuses on distributed temperature measurement using Raman scattering. DAS answers “what vibration event happened and where,” while DTS answers “what temperature changed and where.”
Can the sensing fiber work without field power?
Yes. The sensing cable itself is passive and requires no power along the monitored route, which is one of the advantages of distributed fiber optic monitoring in long-distance and harsh environments.
Which system should be selected for oil and gas wells?
If the requirement is vibration or acoustic event monitoring, choose DAS FS-5100. If the requirement is temperature profile monitoring, choose DTS-1000B. For comprehensive well monitoring, both can be combined.
Can this solution be used outside oil and gas wells?
Yes. DAS FS-5100 can also be used for long-distance pipelines, wires, borders, airports and critical areas. DTS-1000B can also be used for underground cable temperature monitoring.
Can HERTZINNO help configure the sensing layout?
Yes. Provide your well depth, fiber route, monitoring target, required distance, temperature range, acoustic event type and platform integration requirements. HERTZINNO can help recommend the appropriate DAS, DTS or combined configuration.
