Silixa to present at AGU’s Fall Meeting in New Orleans, Louisiana on 13 December 2017

Join the Fiber-Optic Distributed Acoustic Sensor (DAS) for Geophysical and Industrial Applications session to learn about the use of DAS for novel geophysical or industrial applications at AGU in New Orleans, Louisiana on 13 December 2017.

Distributed acoustic sensing provides a flexible and large sensing aperture for acquiring high resolution acoustic data in time and space. The use of DAS in the industry for flow profiling, high resolution borehole/surface seismic imaging, micro-seismic monitoring for fractures has been accelerated with the improvements in the sensitivity, the advances in real-time big data processing and flexible deployment of fibre optic sensing cables.

There is a growing interest in the use of DAS for critical geophysical infrastructure applications such as earthquake and near-surface passive seismic analysis including the development of tailored or new numerical techniques.

Silixa’s oral presentation is titled High Definition Seismic and Microseismic Data Acquisition Using Distributed and Engineered Fiber Optic Acoustic Sensors, and will be presented on 13 December 2017 at 15:12 pm.

Over the past few years Silixa has successfully used DAS to record microseismic events during hydraulic fracturing and re-fracking operations. Detection has been successful in a number of configurations, where the fibre has been in a horizontal treatment well, horizontal well adjacent to the treatment, or vertical observation well. We will discuss the sensitivity of the measurement, range of measurement, ability to localise the events and characteristics of the microseismic event. In addition to discussing the theory we will also present case studies showing the detection and localisation and how these compare to conventional microseismic detection techniques.

Silixa to present at AGU’s Fall Meeting in New Orleans, Louisiana on 12 December 2017

Francesco Ciocca, Silixa’s Environmental Engineer, will be giving a presentation on the use of fibre optic acoustic sensing for hydrogeophysical soil subsurface characterization on 12 December 2017.

Research indicates that surface seismic methods can characterize the hydrogeochemical properties of soil in a controlled environment; however, no technology has been proven outside a controlled environment.

Silixa conducted a study in the United Kingdom to test the exciting potential of utilising distributed acoustic sensing for hydrogeophysical soil layer characterization.

Fibre optic cables were buried horizontally in low permeability bare soil at Silixa’s test facilities in Elstree, UK. Silixa used its intelligent Distributed Acoustic sensor (iDAS) to perform surface seismic to capture the different arrival times of seismic waves traveling through dry and wet soil.

Francesco will present the results of the study along with a comparison of body-wave travel times as well as surface-wave dispersion. He will show how these results point at the prospect of determining site-specific relations between the soil Poisson ratio and saturation.

The study represents a major step towards the use of distributed acoustics above surface for subsurface characterisation. Potential applications include detection of areas of different hydrogeophysical properties, such as those generated by seepages in dams and liquid leaks along pipelines.

The research was conducted within the framework of both the Distributed Intelligent Heat Pulse System (DiHPS) project, funded by the British National Environmental Research Council (NERC), and  the Hi-Freq project funded by the Marie Curie H2020 Research and Innovation Staff Exchange (RISE) Consortium.

Silixa to present on non-intrusive process metering at the Mines and Technology Show in London on 29 November 2017

What if you could meter every flow in your mine or plant? Silixa’s non-intrusive process metering product makes it possible to meter many process flows continuously using only a single, extended length of optical sensing fibre. Recent case studies demonstrate how this technology can be installed throughout a plant, without any disruption to ongoing operations, on slurry, water and gas process pipes.

Daniel Finfer’s presentation (BDM – Process Metering) at the Mines and Technology Show will focus on the sensing method as well as its application for multizone process flow metering. Revealing the details of a successful process flow metering job at an operating minewater treatment plant, he will demonstrate how this technology can be used to enable process control optimisation.

The Mines and Technology Show provides a forum for senior decision makers from mining companies and technology providers to lean about the latest technologies and exchange ideas on how their implementation can enhance productivity and improve cost management.

The Cutting Edge of Fibre Optics: Temperature and Acoustic Applications in Earth Science – workshop

Silixa will be participating in a two-day hands-on workshop on the theory, application and analysis of distributed fibre optic sensing at Nasa’s Stennis Space Center in Mississippi, USA on 9-10 December 2017.

The workshop is organized by the Center for Transformative Environmental Monitoring Programs, CTEMPs, an organization that promotes field-deployable high-precision fiber optic temperature measurement systems, wireless self-organizing multi-parameter sensor stations, and Unmanned Aircraft Systems (UAS) primarily to researchers to find new ways to implement these technologies in earth sciences. Experiment designs, installations, and data analysis is supported by a staff of scientists.

CTEMPs has been providing distributed temperature sensor training for years, but this year they are expanding the scope of the workshop to distributed acoustic sensing as well. Participants will have the opportunity to work directly with Silixa’s intelligent Distributed Acoustic Sensor (iDAS) and XT-DTS, the ruggedized distributed temperature sensor for extreme environments.

Examples will be taken from passive and active DTS applications, active and passive seismic monitoring, and acoustic monitoring in pipes.

Silixa to present on Fibre Optic Acoustic Sensing in Wells at the Non-seismic Geophysical Technologies and Non-Conventional Seismic Conference in London on 11 October, 2017

Garth Naldrett, Silixa’s Chief Product Officer, will be presenting on Fibre Optic Acoustic Sensing in Wells at the Non-seismic Geophysical Technologies and Non-Conventional Seismic Conference in London on 11 October, 2017.

Following several years of comparison around the globe, many geophysicists now accept that the quality of seismic data recorded on optical fibres is equivalent to that of geophones. Over the past three years, DAS surveys have been run on many non-conventional applications, such as carbon sequestration projects, surface buried fibres, inter-well pressure connectivity, mines, dams and ice formation.

Garth’s presentation will describe the impact of fibre technology on conventional seismic, then give three case studies to demonstrate the advantages of fibre optic acoustic sensing in sequestration, microseismic and hydraulic projects.

Silixa to present on multizone, multifluid process flow metering at the Oil Sands Trade Show in Fort McMurray, Canada on September 13, 2017

Silixa’s distributed fibre optic technology enables non-intrusive flow metering of multiple water, slurry, and gas flows on multiple pipes simultaneously using a single, continuous length of optical fibre. This technology is now being used in the minerals mining industry, but has not yet been applied to oil sands operations.

Oil sands operations require significant flow control and adaptive, durable sensors. Silixa’s process metering solution is achieved using low cost, non-intrusive sensing materials which can be easily moved and rotated, or refit to pipes of different sizes and orientations as operations evolve.

Daniel Finfer’s presentation (BDM – Process Metering) will focus on the sensing method as well as its application for multizone, multifluid, non-intrusive process flow metering. He will demonstrate how this new non-invasive technology can be used to enable process control optimisation.

The 2017 Oil Sand Trade Show brings together over 400 suppliers and service companies showcasing the newest technologies, products & services in the oil sands industry.
