Distributed Measurements Unlock the Future of Design
The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

Flow Profiling on Demand – Illuminating the reservoir with Silixa’s intelligent Distributed Acoustic Sensor (iDAS) and ULTIMA Distributed Temperature Sensor (DTS)
As energy demands increase rapidly, the goal of energy companies is to maximize ultimate recovery in an economically sound manner. One critical capability is the accurate measurement and monitoring of production from individual layers / perforated intervals in a multi-zone completion. This data allows operators to optimize zonal production, improve recovery, increase production per well and ...

What's the Big Deal About Patents?
Without innovation and patents, we might still be using candles or oil to light up our homes at night. On January 27, 1880, Thomas Edison received his historic patent that covered the principles of the incandescent lamp. This helped pave the way for the worldwide use of electric light.While Edison was not the first inventor trying to create a useable light source, he succeeded and surpassed ...

Singapore’s used water underground infrastructure to be monitored with Distributed Fiber Optic Sensing (DFOS) technology by fibrisTerre
Singapore’s Deep Tunnel Sewerage System The Deep Tunnel Sewerage System (DTSS) is a key part of the long-term Singapore’s used water system, which comprises a network of link sewers leading to two major tunnels (Phase 1 & 2) crisscrossing Singapore with three large water reclamation plants (WRP), as well as outfall pipes. DTSS uses deep tunnels to convey used water entirely by ...

Assessment of detection limits of fiber-optic distributed temperature sensing for detection of illicit connections
Distributed temperature sensing (DTS) with fiber-optic cables is a powerful tool to detect illicit connections in storm sewer systems. High-frequency temperature measurements along the in-sewer cable create a detailed representation of temperature anomalies due to illicit discharges. The detection limits of the monitoring equipment itself are well-known, but there is little information ...

Mind the Bandgap - A Temperature Profiling Technology Comparison
When it comes down to determining temperature in environmental media, there are many options - from fiber-optic to infrared sensing technologies - to observe and quantify the relative kinetic energy of a material. For single point data acquisition and a given specific temperature range and target medium, of course certain technologies are more optimal than others. When it comes to ...

Fibre optic sensors as a non–destructive tool for structural monitoring
Structural monitoring is a diagnostic tool for detection of defects/damages and for scheduling maintenance operations. It is essential to determine the safety of the structures by Non–Destructive Testing (NDT) for evaluation of strength/integrity. This assessment is required for the repair, rehabilitation and life extension of the structure. Fibre Optic Sensors (FOS) are attractive sensing ...

Increasing Security Resilience with Value Engineered Solutions
It’s safe to say that 2020 has been an unusual year; the impact of COVID-19 has been felt around the world, with everyone adapting to what is commonly called ‘the new norm’. Individuals, families, companies, organisations and even countries are having to change the way they operate, how they interact and how they travel. The impact on businesses has been massive, home working ...

Searching for storm water inflows in foul sewers using fibre-optic distributed temperature sensing
A major drawback of separate sewer systems is the occurrence of illicit connections: unintended sewer cross-connections that connect foul water outlets from residential or industrial premises to the storm water system and/or storm water outlets to the foul sewer system. The amount of unwanted storm water in foul sewer systems can be significant, resulting in a number of detrimental effects on ...

Distributed Thermal-Acoustic Data Integration
Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage field. ...

Why Wavelength Matters in Spectroscopy
In its broadest sense, spectroscopy is used to investigate and measure spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter absorbs or emits light and will give off a unique spectrum depending on the frequency at which the interaction with light occurs. This makes it a useful tool for studying molecules, and for determining the composition of an ...

Using distributed temperature sensors to monitor an Antarctic ice shelf and sub-ice-shelf cavity
ABSTRACT. Monitoring of ice-shelf and sub-ice-shelf ocean temperatures represents an important component in understanding ice-sheet stability. Continuous monitoring is challenging due to difficult surface access, difficulties in penetrating the ice shelf, and the need for long-term operation of non-recoverable sensors. We aim to develop rapid lightweight drilling and near-continuous fiber-optic ...
