Fiber Optic Distributed Temperature DTS Monitoring for Oil & Gas
Oil reservoirs represent a harsh environment for sensitive electronic components. Equipment deployed downhole must be able to perform 100 % reliably while with- standing heat, pressure, moisture, vibration, and corrosion. Breakdowns can cause unacceptable delays and lost output costing hundreds of thousands of dollars. LIOS Technology offers the most reliable and functional continuous downhole temperature sensing and logging system available for both simple and complex wells. Our module- based system and open standard protocols enable us to offer you customized solutions for your unique needs.
Features
- Impressive track record – more than 2000 successful fixed installations in more than 80 countries on all continents
- Dependable and field proven system design – no sensitive electronic components or power supply downhole, only the Fiber Optic cable acting as the sensor
- Rugged and durable semiconductor laser diode sensor. Fulfils Telcordia GR-468 quality standard with average product lifetime of 25+ years
- Patented OFDR technology (MM or SM) based on Raman effect delivers temperature readings accurate to within ± 0.06° C (±0.1 F) and 0.5 m (1.5 ft) along the entire sensor length from distances up to 30 km (98425 ft) away
- Market leading calibration features like automated point calibration using 3 rd party temperature source, multi fiber segment calibration and double ended calibration operation mode
- Low-cost third-party optical pressure gauges can be added using the same fiber optic cable for even more detailed measurements
- The multichannel LIOS DTS unit can accommodate up to 8 independent fibers, enabling comprehensive surveillance and Real Time Field Management (RTFM) of multiple wells
- Entirely self-contained DTS unit transmits measurement data via cyber secure, TLS encrypted link to remote SCADA database systems. No on-site PC to power or hack into
- No need to visit well-site to collect data
- Entire DTS system is independently certified for quality by VdS [the German asset insurers association] and many other international certifying bodies
Easy to install and integrate
Here at LIOS Technology, our goal is to deliver optimal communication solutions to you. We supply your specialists with accurate and real-time information delivered to their desks round-the-clock so that critical decisions can be made immediately.
LIOS Technology can easily and economically interface its DTS temperature and pressure measurement system with your system to create a fully Data-to-Desk solution customized to your needs.
Accurate, continual, and real-time temperature reading along the well path can give you valuable information about the condition of both the reservoir and downhole completion. This enables you to adjust parameters and schedule maintenance for maximum hydrocarbon production and minimize downtime.
Temperature readings allow you to
- Enhance oil and gas recovery
- Increase production yields
- Track well production changes over time
- Reduce frequency of well interventions
- Improve reservoir management strategies
- Supply in-flow distribution along the reservoir
- Detect early water, steam (SAGD), or gas breakthrough and its location
- Observe steam flooding performance
- Verify and allocate cross flow
- Determine skin factor
- Check integrity of casing and completion
- Monitor and optimize gas lift valve operation
- Detect stuck or leaky valves, perforation inflow, porous insulation, wax deposits, hydrate precipitation, etc.
