QOREX sets a new benchmark for performance and reliability with the HydroLight™ DTS system, designed to operate indefinitely under full hydrogen exposure to 300°C with no compromise in performance or longevity. Since its introduction, field results validate this performance with a track record unrivaled for fiber optic products introduced in the challenging thermal recovery sector. QOREX HydroLight™ system is the only DTS product on the market that reports data directly from the data acquisition unit without any post-processing, and a truly permanent solution requiring no maintenance or calibration once installed and commissioned for the lifetime of the well.
QOREX is recognized as the leader in downhole fiber optic systems in Oil & Gas, specializing in the challenging thermal recovery sector. Now part of Petrospec Engineering, the merged company offers the most complete reservoir monitoring product line to this sector, building off the solid track record of Petrospec’s leading Sensor Tube™ line to now offer fiber optics, Petrospec now has complete capabilities under one roof from design, integration, installation and data management for fiber optic technology. Specializing in thermal heavy oil, the company combines critical oilfield services and completions expertise with best-in-class fiber optics technology to offer superior product performance and system reliability. No other company has the depth of knowledge and experience in these key areas, and as a turn-key provider allows the company to best support and warranty the product.


Understanding customer needs after 15-years of developing and delivering downhole fiber optic well monitoring systems to the Oil & gas industry, the principals at QOREX complete the HydroLight™ product line with the most flexible and robust surface and data acquisition equipment to allow installations in any environment from remote desert to arctic conditions. A full set of data connection and storage options are available as well as data management and visualization tools for easy desktop DTS data viewing and analysis.

Engineering refinements to the HydroLight™ platform have led to the upgrade of the DTS cable system for rating beyond 500°C to address emerging downhole electrical heating applications. With several systems installed and operating, QOREX is emerging as the leader in this nascent application. QOREX is also combining distributed acoustic sensors with Raman DTS, with a fully integrated offering specifically for high temperature thermal recovery wells. Other integrated systems combining pressure and temperature sensors are slated for commercial introduction upon successful field validation.
