Silixa to present at SEG 2018, in Anaheim, California, USA on 19 October 2018

Silixa will be presenting at the Society of Exploration Geophysicists International Exposition and 88th Annual Meeting in Anaheim, CA, USA on 19 October 2018.

Mahmoud Farhadiroushan, Silixa’s Executive Director, will present on Fiber Optic Distributed and Engineered Acoustic Sensors for New Seismic and Microseismic applications at the Validating Measurements, Developing Processing Methods, and Integrating to Optimize Velocity Models for Improving Subsurface Imaging DAS workshop.

His presentation will focus on new applications enabled by Silixa’s Carina® Sensing System, the engineered acoustic sensor, that has 100x better SNR than other DAS systems due to its advanced sensing architecture.

In unconventional wells, in addition to seismic and microseismic measurements, the low frequency response of the Carina Sensing 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 as well as hydraulic connectivity between offset wells.

The system also has a high potential for use in subsea applications either by marinization of the DAS interrogator unit for direct installation near the wellhead to avoid the long-tie back fiber attenuations, or by combining existing fibers in the subsea umbilical with the enhanced optical signal received from the downhole Constellation fiber.

Mahmoud will present some initial results demonstrating the feasibility of deploying the new engineered acoustic system in subsea wells with long-offset over 20km distance.

Silixa and Uppsala University collaborate with SKB in unique experiment

The protection and safeguarding of the environment today is of primary importance. Nuclear power agencies are taking significant additional measures to introduce and adopt innovative monitoring techniques in respect of waste storage.

The Swedish Nuclear Fuel and Waste Management Company (SKB) in collaboration with HydroResearch Sam Johansson AB, Uppsala University and Silixa Ltd have introduced Silixa’s distributed fiber optic sensing  systems to evaluate its monitoring capabilities of conditions in the sub-surface and deliver feedback to engineers to assist with the design and construction processes of a new waste storage facility.  The system is currently being evaluated together with existing technologies in an effort to expand the monitoring capabilities not only during construction but also through the operational life of the repository.

The main scope of this feasibility trial, which is the first of its kind, is to compare technologies for seismic monitoring and to map and characterize the geological formation, which is achieved using active and passive seismic techniques.

During the first survey, geophones and different cable constructions were installed in a monitoring borehole to an initial depth of 200 m. Additionally the borehole was instrumented with a heat active optical fibre cable to allow characterisation of the thermal conductivity along the entire depth using active distributed temperature sensing.  Preliminary tests have produced encouraging results using both the intelligent Distributed Acoustic Sensor (iDAS™) and Carina® Sensing System, as well as the ULTIMA™ DTS,  distributed temperature sensor.

Distributed sensing systems offer an unprecedented opportunity for applications in the environmental sector, where the processes are on scales from centimetres to kilometres. Distributed fibre optic monitoring offers fine spatial resolution and the ability to easily repeat measurements to create a temporal profile. This can be delivered for  large areas, long lengths and at locations where conventional transducers are not applicable or cost effective.

Temperature sensing has been proven to be the technique of choice for numerous environmental applications, such as soil moisture monitoring, groundwater-surface water interactions in streams, fractured rock characterisation and flow dynamics into boreholes.

Distributed acoustic sensing has been used in many seismic acquisitions to date, encompassing vertical seismic profiles (VSP), in both flowing and non-flowing oil wells, CO2 storage wells and surface seismic surveys.

Both techniques have been deployed in geophysical monitoring applications.

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.
