Version 2.9 of DxS Browser Now Available

OptaSense, a QinetiQ company, is excited to announce the release of Version 2.9 of the OptaSense DxS Browser Visualization Software suite. The software allows users to easily integrate large distributed data sets into workflows, including 3D depth, time and measurement data, while managing quality control, analysis and interpretation.

Several major improvements have been incorporated into the version 2.9 release, including:

  • Sparse data set visualization – The DxS charting framework has been upgraded to provide a mode for displaying very sparse datasets, by removing the gaps between data segments and displaying the data on a non-linear time scale.  This enhancement will provide support for analyses of datasets involving looking for long term trends, and easier comparison of datasets captured at widely separate time intervals.  At the same time, the representation of areas on the waterfall where no data is available has been changed to make it more readily distinguishable from areas of low signal.
  • 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.

High Backscatter fiber improves DAS performance

OptaSense, the industry leader in Distributed Acoustic Sensing (DAS) solutions, has integrated the latest high backscatter optical fiber technology with its industry leading DAS interrogators for unparalleled downhole measurement performance.

Combining high backscatter fiber with OptaSense’s DAS interrogator unit delivers the best possible sensitivity, resolution and signal to noise ratio delivering high-fidelity measurements:

  • Enhanced seismic data acquisition
  • Improved production monitoring
  • Increased microseismic event detection and count
  • More sensitive strain measurements for detection of frac hits

The unique high backscatter fiber used by OptaSense provides a continuous amplification of the DAS signal, enabling flexibility in setting measurement parameters in the field, including channel spacing and gauge length.

This flexibility to optimize interrogator parameters to the specific physical processes in the well and reservoir is an important departure from the restrictions that other commercially available enhanced fibers have in terms of pre-set gauge lengths and channel spacing.

Field Demonstration of High Backscatter Optical Fiber

Demonstration of the technology has been conducted in wellbores by comparing the performance of high-backscatter and standard single-mode fibers. This comparison was made with the shortest gauge length typically used in fracture monitoring applications. The enhanced backscatter fiber results in clear seismic signals with reduced background noise and improved signal fidelity.

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.
