  • DTS datum trace import and export – the DxS Browser will now allow DTS data datum traces to be shared between projects and datasets for consistent and efficient data analyses.
  • Time-shift capability for imported curves – the DxS Browser now allows users to clean up imported data series (curves) by applying timestamp corrections.
  • Enhanced data tree refresh button operation – the usability of the DxS Browser has been enhanced by allowing the data tree to be refreshed readily when curves have been modified by DxS plugins.
  • Transferable waterfall colour maps – both the colour map, and the colour map limits, can now be copied from one waterfall to another, improving user efficiency when presenting data.
  • Interpolating line plots – the user can now select for interpolation across large gaps when drawing line-plots of sparsely or unevenly sampled data series.

OptaSense Demonstrates Ability to Detect Pipeline Leaks Using Fiber Optic Sensing in Unique Testing Environment

OptaSense, a QinetiQ company, a world leader in fiber-optic-based acoustic sensing, recently invited several key customers and interested parties to witness a one-of-a-kind demonstration of its fiber-optic-based pipeline leak detection technology.

Even the smallest leak in a pipeline carrying oil, gas, or water, if not detected quickly, can result in significant financial loss and potential environmental damage. Identifying and locating these leaks quickly allows Operators to take immediate steps to address the issue and mitigate any potential negative impact.

Not only do pipeline operators need a system that detects leaks, it’s critical that they have confidence that their system of choice can effectively detect leaks under different flow conditions and in varying environmental conditions. Traditional testing methods typically fall short because of their inability to replicate “real-world” conditions.

To prove the effectiveness of the leak detection system delivered by OptaSense, guests were invited to view a unique demonstration at the Centro de Tecnologia em Dutos, or CTDUT, pipeline testing facility in Rio de Janeiro, Brazil.  The unique facility features a closed-loop pipeline run that allows engineers to test leak detection systems in an actual pipeline flow situation. By creating a leak in a targeted section of the pipe, OptaSense was able to validate that their system was able to immediately identify a leak and accurately pinpoint its location along the pipeline.

During the demonstration, the test pipeline, carrying water and inert gas, was pressurized to the point that a burst disc installed on a section of the pipe was triggered. The OptaSense system was able to identify a leak, down to 15 lpm, within seconds of its occurrence and provide critical geolocation information to 10m, back to the control room onsite, validating that the system works exactly as intended.

“OptaSense has participated in many industry sponsored tests over the years but these have fallen short of replicating the behavior of leaks in real life conditions, leaving operators short of full performance validation,” said Dr. Chris Minto, Engineering Director for OptaSense. “To close this gap, OptaSense has funded the most comprehensive and valid set of tests to date, providing a full set of performance, accuracy and reliability data to validate our unique four-mode leak detection specification.

In conjunction with the demonstration, Minto also delivered a presentation at the Rio Pipeline 2019 conference in Brazil, “Challenges in Validation and Verification of External Fiber Optic Leak Detection Systems,”  which focused on the need pipeline leak detection providers to demonstrate the efficacy of their system in a controlled manner and the need for customers to gain assurance their system is truly meeting their operational and safety objectives.

With this real-world testing approach taken by OptaSense, pipeline operators can have confidence that the system they select for leak detection will work and provide the level of protection they expect.

OptaSense Collaborates with Leading Research Institution to Install Fiber Optic Seismic Array

OptaSense, a QinetiQ company, announces a collaborative research agreement with the Stanford School of Earth, Energy and Environmental Sciences that includes the installation of an on-campus fiber optic seismic array.

Using OptaSense distributed acoustic sensing (DAS) technology to sense ambient noise and seismic energy, the seismic array will enable scientists to conduct research in passive seismology. Located adjacent to a major geologic fault zone, the San Andreas Fault, the seismic array will be used to image subsurface properties that provide scientists a better understanding of the complex geology in the Bay Area.

The seismic array will leverage a two kilometer long, standard telecommunications fiber optic cable. The OptaSense DAS system will transform this fiber into thousands of distributed sensors capable of detecting changes in pressure, temperature and strain. A single fiber can create a seismic array with thousands of channels, allowing for dense sampling of seismic wavefields and the ability to detect weak signals.

Utilizing a Coherent Optical Time Domain Reflectometer, or Interrogator Unit (IU), the OptaSense system sends laser pulses down the length of the fiber to measure and observe changes in the backscattered light, indicating movement in the earth adjacent to the fiber.

In addition to enabling research in seismology, the OptaSense DAS system will support potential studies in fields such as structural engineering, communications, infrastructure monitoring, and security.

“Collaborating with one of the world’s foremost academic institutions is particularly exciting for OptaSense. For the first time, we are putting our DAS technology into the hands of the academic community and working with them to explore new applications and techniques. Through this collaboration we will be able to mature the understanding and expand the capabilities of DAS for the benefit of the wider seismic community,” commented David Hill, Chief Technology Officer at OptaSense.
