What Silixa does

Silixa Ltd is a UK-headquartered (Elstree) provider of distributed fiber optic sensing (DFOS) systems and solutions, founded in 2007 and operating as a wholly-owned subsidiary of Luna Innovations within the Luna Sensing Group since its January 2024 acquisition for $38 million. The company designs and sells interrogator units and application services built on Optical Time-Domain Reflectometry, Raman, and Brillouin scattering principles, delivering continuous real-time distributed acoustic (iDAS™, iDAS-MG™), temperature (ULTIMA™ DTS, XT-DTS™, Heat Pulse System), and strain (iDSS™) measurements over multi-kilometer fiber lengths, with the Carina® Sensing System platform serving as the integrated offering for permanent reservoir monitoring, subsea 4D seismic, well integrity, and carbon storage surveillance. Specialized services such as Carina® XwellXpress, Carina® 100XLog, ArrayFrac™, Carina® CarbonSecure™, and DamPulse address hydraulic fracture monitoring, production logging, CCUS monitoring, and tailings dam safety respectively.

Silixa serves enterprise and government customers across oil and gas (upstream operators), mining (e.g., Anglo American, Mogalakwena Platinum Mine), carbon capture and storage (e.g., CO2CRC at Aquistore and Otway), geothermal energy (Brady Hot Springs), natural environments, and defense (U.S. Navy via BlueTIDE 2025, FMV via Subvision AB collaboration), with named operations in the UK, US, Saudi Arabia, Norway, Australia, Canada, and Iceland. Revenue is generated through direct enterprise sales of hardware systems, quote-based project pricing on multi-year contracts, and complementary data and edge-computing services; pricing is not publicly disclosed. The company employs 101-250 staff and is led by CEO Glynn Williams with a founder-led technical bench including CTO Tom Parker, co-founder Mahmoud Farhadiroushan, and chief scientist Sergey Shatalin.

Core offering

Silixa designs, manufactures, and sells distributed fiber optic sensing (DFOS) systems based on OTDR principles that provide continuous, real-time measurements of acoustic signals (DAS), temperature (DTS), and strain (DSS) along many kilometres of optical fibre without additional transducers. The company also delivers specialized monitoring services such as hydraulic fracture diagnostics, well logging, CO2 storage surveillance, and tailings dam monitoring for the oil and gas, mining, carbon capture, energy, environmental, and defense sectors.

Product overview

Silixa is a leading independent provider of fibre optic-based distributed sensing solutions, offering a comprehensive portfolio of distributed temperature, strain, and acoustic sensing products and services. The product portfolio is built around core technology platforms: iDAS™ for distributed acoustic sensing, ULTIMA™ and XT-DTS™ for distributed temperature sensing, iDSS™ for distributed strain sensing, and the Carina® Sensing System for permanent reservoir monitoring. These hardware platforms are complemented by specialized application services including Carina® XwellXpress for hydraulic fracture monitoring, Carina® 100XLog for well logging, ArrayFrac™ for frac diagnostics, Carina® CarbonSecure™ for CCUS monitoring, and DamPulse for tailings dam monitoring. The company operates as part of the Luna Sensing Group and serves sectors including oil and gas, carbon capture and storage, mining, natural environments, energy, and defence. Digital services including edge computing and data analytics complement the hardware offerings to deliver complete monitoring solutions from strategy through execution.
