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 presenting at the 4th Annual Offshore Well Intervention Europe Conference in Aberdeen on 27 April, 2017

Craig Milne, Silixa’s VP Oil & Gas Applications, will be presenting on Inwell Applications for Distributed Fibre Optic Sensing at the OWI Europe Conference in Aberdeen on 27 April 2017.

His presentation will focus on the latest developments in distributed acoustic sensing and will show through a case history of leak detection behind casing how distributed acoustic sensing offers conventional sensor performance simultaneously at every point along the wellbore.

Craig will also offer an overview of other applications such as seismic, microseismic and production profiling.

Distributed acoustic sensors gaining momentum in downhole multiphase flow measurement

Distributed acoustic sensing makes it possible to monitor the acoustic field along the entire length of a standard fiber optic cable, hence becoming a recognized solution for high accuracy in-well flow surveillance, including downhole multiphase flow measurements.

Garth Naldrett, Silixa’s Chief Product Officer, presented on Silixa’s latest developments in multiphase flow metering at the Multiphase Metering and Fibre Optics Monitoring – Recent Developments and Challenges SPE Workshop in Dubai, UAE on 22-23 March 2017.

His presentation, titled From Distributed Measurement to Multiphase Flow, discussed how distributed fibre optic measurements allow the physics to be constrained in space and time and how interpretation errors can be reduced by deriving additional information from DTS and DAS.

Examples of measurements that can be derived from DAS include the speed of sound, the use of Doppler Shift and the direct measurement of flow eddies, which allow better determination of flow rates and density.  Garth’s presentation also discussed the application of these derivatives, described the methods employed and provided case studies of downhole multiphase flow measurement.

Garth also presented on Industry Solutions for Distributed Sensing Big Data Management, providing an overview of the data types generated by a typical fibre optic monitoring system and offered  insight into the range of data rates and data volumes generated.
