Silixa to present at the Copper Cobalt Africa – 9th Base Metals Conference 2018 in Livingstone, Zambia on 12th July 2018

Daniel Finfer, Silixa’s BDM – Mining, will be presenting on “Flotation process metering of concentrate, slurry, air and water flows using non-intrusive fibre-optic sensing,” at the Copper Cobalt Africa – 9th Base Metals Conference in session 6A, titled “Concentration and flotation.”

During his talk, Daniel will present a case study on a pilot at Anglo American’s Mogalakwena North Concentrator, where a single, continuous length of optical fibre was used to meter concentrate, water, slurry and air flows. The results indicate that this new technology can meter many process flows simultaneously throughout flotation plants using nonintrusive instrumentation, opening a new era for closed loop flow control in flotation.

Jointly hosted by the Mining and Metallurgy Technical Programme Committees of the Southern African Institute of Mining and Metallurgy (SAIMM), the conference aims to provide a unique forum for discussion, sharing of experience and knowledge for those interested in the processing of copper and cobalt in an African context. It also promotes an understanding of new and existing technologies that can lead to safe and optimal resource utilization.

Silixa to present at the Fibre Optic Sensors in Surface and Borehole Geophysics Workshop at EAGE 2018

Join us for our presentation at the Fibre Optic Sensors in Surface and Borehole Geophysics Workshop (WS08) at EAGE 2018 in Copenhagen, Denmark on 11 June 2018 at 9.00 am.

Our presentation, titled “Seismic and Microseismic Detection Using a Wide Dynamic-range Distributed and Engineered Fiber Optic Acoustic Sensor”, describes the rapid development of the fiber optic acoustic sensing technology that seeks to disrupt the conventional geophysical surveying methods and enables the realisation of new applications where the fibre optic cable can be easily utilised as a dense wide-aperture phase-array sensor.

In offshore applications the permanent installation of fiber optic cables along the production and injection wells enables more frequent and cost-effective distributed seismic data to be acquired on existing single mode and multimode fibers using our iDAS™.

In unconventional wells, in addition to seismic and microseismic measurements, the low frequency response of the DAS system down to milli-Hertz is used to monitor the hydraulically induced strain effect in offset wells that can provide valuable data for improving the understanding of the rock properties and determining the fracture heights.

Silixa has also recently developed the next generation Carina® Sensing System that combines the properties of engineered Constellation™ fiber with low-noise and wide dynamic-range opto-electronic interrogator to achieve significant improvements in signal-to-noise performance, beyond the performance of geophones.

We will also present some initial results demonstrating the feasibility of deploying the Carina Sensing System for long-offset subsea wells.

How to create the world’s largest flow measurement network in your plant

1 February 2018

How to…create the world’s largest flow measurement network in your plant (or how to embrace IoT without becoming beholden to an automation behemoth) by Daniel Finfer, Silixa’s BDM for Process Metering.

Process control and automation is the key to getting a difficult plant to run efficiently. Traditionally, plant operations rely on the experience and tacit knowledge of a few key personnel. As the shift changes, so too does the plant set point and the reaction plan for transients. The Internet of Things (IoT) and Industry 4.0 promised to change all of those challenges. “Give us your plant!” cried the automation behemoths, “and we can automate away the shift effect, and predict your next pump failure!”.

The challenge is that Industry 4.0* relies on the installation and continuous operation of sensors throughout the plant, and electronic sensors are expensive to install and maintain. Electronic sensors need to communicate with a central computer, and who is going to look at all of those accelerometer plots and pressure traces? So, in a typical operation, the automator sells the system to management and then comes to execute the installation which includes many beautifully designed sensors. Usually, it is determined that many of the expensive sensors such as flow and density meters can be reduced in number, as machine learning will enable the key operating information to be derived from pressure transducers or esoteric arrangements of thermocouples. Then, at some point during the installation operation, a management cost review is executed, and the number of sensors to be installed is reduced by an order of magnitude. The automator then explains that the number of sensors in place is no longer sufficient to enable machine learning to be used. Alternatively, the plant is upgraded, and the sensors are no longer compatible with the new layout. In either case, the plant is left back where they started: total reliance on a few, key, experienced personnel who have developed a feel for the plant (minus the CapEx for a large sensor management system which will be outdated in 36 months).

This is where distributed fibre optic (DFO) sensing can help (full disclosure: I sell distributed sensing systems). Distributed fibre optic sensors such as DAS (distributed acoustic sensing) and DTS (distributed temperature sensing) make it possible to measure acoustics, flow, or temperature anywhere and everywhere in the plant using nothing more than telecoms-grade optical fibre. Since DFO senses with fibre and doesn’t rely on highly engineered sensing stations, the layout can be adapted as the plant adapts and grows (you want it to grow, right?). Also, DAS and DTS plant sensing installations don’t require the capital and operational expenses incurred through the installation of communications and power infrastructure. The opportunity to measure flow non-intrusively everywhere in the plant means that the process engineer doesn’t have to rely on inferential data to figure out how well that manifold is working, or whether that cyclone is running at its maximum rate.  And we don’t have to worry about being costed out…because the cost per measurement of our technology decreases as the number of plant processes monitored using fibre increases.

Silixa is excited to be introducing DFO into mining plants. As we will be showing in conference papers during the course of 2018, we are beginning to see how some traditionally challenging measurements can be addressed using intrinsically safe, optical layouts and reliable, non-intrusive adaptable installation procedures. We look forward to hearing from you.

Daniel Finfer  will be presenting case studies for our plant process monitoring products at GECAMIN WaterCongress2018 and SAIMM Copper Cobalt 2018.

*Industry 4.0 refers to de-centralised decision automation as enabled through massive sensor networks and big data connectivity. For more information on this area, see some recent thoughts from the Forbes Insights team here.

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.
