Silixa appoints Glynn Williams as CEO

Silixa Ltd announces the appointment of Glynn Williams as CEO with effect from 16 October 2017.

Glynn brings over 30 years’ experience in the oil and gas industry having held various senior level positions around the globe. His expertise extends to drilling, completions, well testing, cased hole logging and emerging disruptive technologies.

Mahmoud Farhadiroushan, who successfully built Silixa from inception into the leading distributed fibre optic sensing company, will remain Executive Director, responsible for the long-term strategic planning and product innovation, as well as key customer and supplier relationship management. Commenting on Glynn’s appointment, he said: “We are delighted to welcome Glynn to our leadership team. His expertise is invaluable to us as we look to make a step change in what we can achieve commercially across multiple sectors.”

“I am impressed with the tremendous progress Silixa has made in advancing distributed sensing technology and its applications by developing the market leading ULTIMA™ DTS, XT-DTS and iDAS™ systems. Now with the addition of the Carina® Sensing System, we are not only redefining the limits of what is possible, but also extending the repertoire of new commercial and operational benefits it can offer to our customers,” said Glynn.

Alison Goligher, Silixa’s Executive Chair, added: “Glynn has the experience, leadership credentials and deep sector knowledge to expand our commercial and operational capabilities. I am confident we can make considerable progress in transforming how distributed sensing is used in the industry.”

Glynn began his career with major service companies. In 1995 he co-founded Sensa, a pioneering fibre optic sensing solutions provider. After the company’s sale to Schlumberger in 2001, Glynn acted as an independent director on three private equity backed businesses and became full-time Chief Executive of SPS International.

He holds a BSc in Mining Engineering from the University of Wales. He is a member of the Society of Petroleum Engineers and a Fellow of the Institute of Directors.

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.
