Silixa to present at the European Geosciences Union General Assembly in Vienna, Austria on 27 April, 2017

Silixa Ltd will be presenting the results of several active distributed temperature sensing (Active-DTS) surveys at EGU 2017 in Vienna on 27 April, 2017.

Active-DTS is a technique that combines distributed temperature measurements with a heat pulse sent along the optical cable. Soil water content profiles can be extracted from temperatures trends during heating and/or cooling phases.

Results from both the active DTS survey and independent in-situ and laboratory measurements will be presented, including the observed relationship between thermal conductivity and moisture content at the study site and how it compares against theoretical curves used by the AHFO methods. The spatial variability of soil thermal conductivity and soil moisture content, as observed using the different methods, will be shown and an outlook will be provided of how the AHFO method can benefit soil sciences, ground source heat pump applications and groundwater recharge estimations.

Presentation Title: Using Actively Heated Fibre Optics (AHFO) to determine soil thermal conductivity and soil moisture content at high spatial and temporal resolutions
Presentation Type: Poster Session: HS2.3.1 – Innovative sensing techniques and data analysis approaches to increase hydrological process understanding
Session Date and Time: 27 Apr 2017, 08:00-19:30
Location: Hall A, board number A.116

EGU brings together geoscientists and researchers from all over the world and provides them a forum where they can present their ideas and latest research results in the field of geoscience.

Silixa announces the Carina™ Sensing System

Silixa announces the Carina™ Sensing System; distributed coverage with sensitivity beyond that of point sensors, enabled by Constellation™ fibre.

Carina is a versatile fibre optic sensing system and comprises an advanced optoelectronics interrogator and sensing cables, which are equipped with the new family of engineered Constellation fibres; to gain two orders of magnitude more sensitivity (100x or 20dB improvement) over that achieved with standard fibres.

Silixa has led the way in the development of high performing distributed fibre optic sensors since 2007; the intelligent Distributed Acoustic Sensor (iDAS™) is at the forefront of DAS performance in terms of stability, range, spatial resolution and phase coherency.

Applications such as borehole seismic, well production profiling, pipeline leak detection and perimeter security have benefited from the inherent nature of the technology whereby a standard optical fibre acts as a huge sensor array.

Now a transformative performance improvement has been achieved by advancing the state of the iDAS optoelectronics interrogator architecture, together with the introduction of new and proprietary Constellation fibre. This fibre is engineered to provide bright scatter centres along its length to capture and reflect more light back to the interrogator. This is achieved without introducing significant loss to the forward propagating laser pulses.

For the first time, with Carina Sensing System it is possible to achieve the massive coverage of distributed sensors without having to compromise on sensitivity.

The significance of this step change in performance is most acute in applications with low acoustic signal levels such as is common with leak detection and production monitoring, where acoustic information can be present at, or below, the inherent system noise floor of the current technology and therefore difficult to detect.

Borehole seismic applications stand to benefit from greatly reduced source effort required to achieve high quality, densely sampled seismic data leading to significantly reduced operating time and costs. The higher sensitivity also paves the way for passive seismic and microseismic monitoring across the large aperture of the fibre and enables the possibility of vast, cost effective, sensing arrays using a single cable

In addition to standard singlemode and multimode optical fibres, a family of Constellation fibres can be incorporated into a number of different cable types for downhole and surface deployment. Silixa also offers an intervention solution using this technology where the fibres are integrated into a hybrid electric-line cable.

Silixa to attend AGU’s Fall Meeting in San Francisco, USA on 15-19 December, 2014

The American Geophysical Union’s Annual Fall Meeting is the largest worldwide conference in the geophysical sciences, showcasing the latest technology, research and emerging trends in earth sciences. The technical program includes presentations on new and cutting-edge science, much of which has not yet been published.

Thomas I Coleman, Silixa’s Environmental Engineer, will be presenting on the use of fiber-optic distributed temperature sensing (DTS) for borehole applications on 18 December 2014; between 8:00 AM – 10:00 AM. (Abstract Title: Quantification of Natural Gradient Flow Using Active Fibre Optic DTS in Sealed Boreholes, NS41C-06)

Distributed Temperature Sensing for process monitoring in deep fractured rock environments has been used in the oil and gas industry for over two decades. Improvements in DTS system resolution, methodology advancements, and improved data processing techniques have all contributed to a recent increase in the use of DTS  for shallow fractured rock hydrogeologic applications.

In his presentation, Thomas will focus on a powerful advance in DTS methodology, the use of response data collected during active cable heating, to better characterize natural gradient flow processes.
