GESO

What GESO does

GESO GmbH & Co. Projekt KG is a privately held German engineering company headquartered in Jena, Thuringia, that has specialized since 1993 in fiber optic sensor systems for industrial and infrastructure monitoring. The company designs and manufactures measurement hardware, sensor cables, and associated software built on two core technology platforms: Distributed Temperature Sensing (DTS) and Fibre-Bragg-Grating (FBG) strain sensors. DTS offerings are sold in configurations ranging from 2 km to 30 km per channel, with borehole-class variants achieving 12.5 cm spatial resolution; FBG chains detect strain in the micrometer range and are suited for tunnels, bridges, slopes, and other geotechnical assets. Product lines include GESO StorageControl, CementationControl, and SolutionControl for underground storage and well monitoring, GESO-LDS for pipeline leak detection, GESO FireFinderM for smouldering fire detection under mining conveyor belts, GESO-TMS for linear temperature monitoring in dams and geothermal systems, and GESO-SMS for FBG-based strain, vibration and temperature monitoring. Customers are technical decision-makers at European oil & gas majors (VerbundnetzGas, E.ON Ruhrgas, EWE, DEA, RWE Gas, IVG Caverns, Wintershall, ExxonMobil, Gaz de France, RAG, Gasunie), mining operators (RAG Deutsche Steinkohle, JSC Vorkutaugol, esco), chemicals and district heating utilities (Solvay, Bayer, Stadtwerke), and public dam authorities (Landestalsperrenverwaltung Sachsen, Ruhrverband), together with research institutes such as RWTH Aachen, Okayama University and the Leibniz Institute for Photonic Technologies.

GESO generates revenue through five streams: (1) hardware and software sales of sensor cables, measurement devices, and data analyzers; (2) on-site measurement services including data collection, analysis and interpretation; (3) bespoke system solutions and consulting covering feasibility studies, configuration and installation; (4) hardware rental with standard software; and (5) training courses. Pricing is not publicly disclosed and is handled through direct consultation, consistent with long-cycle, project-based B2B industrial instrumentation sales. The company operates a direct sales motion targeting engineering and technical decision-makers across oil & gas, mining, hydraulic engineering, geothermal, and geotechnical verticals, supported by a technical content marketing presence (German and English product pages, downloadable conference papers and journal publications) and partner relationships with integrators and research institutes. The company holds DIN EN ISO 9001:2015 and DIN ISO 45001:2018 certifications from TÜV and ATEX certification for FireFinderM, supporting qualification for enterprise and government tenders in safety-critical environments.

Core offering

GESO designs, manufactures, and applies fiber optic sensor systems based on Distributed Temperature Sensing (DTS) and Fibre-Bragg-Grating (FBG) technologies for industrial monitoring. Its product portfolio addresses linear temperature, strain, and vibration monitoring in pipelines, underground gas storage facilities and production wells, solution mining caverns, mining conveyor belts, hydraulic structures (dams), geothermal/environmental engineering sites, and tunnels, bridges, and slopes. In addition to hardware, GESO provides customer-specific system solutions, on-site measurement services, hardware rental, and training as professional service offerings.

Product overview

GESO offers a portfolio of fiber optic sensor-based monitoring products built on Distributed Temperature Sensing (DTS) and Fibre-Bragg-Grating (FBG) technologies. The product line includes GESO StorageControl S, GESO CementationControl S, and GESO SolutionControl S for underground storage and well monitoring; GESO-LDS for pipeline leak detection; GESO FireFinderM for fire detection in mining applications; GESO-TMS for linear temperature monitoring across hydraulic engineering, geothermal, geotechnical, and building applications; and GESO-SMS for strain, vibration, and temperature monitoring using FBG sensors. These products share common fiber optic sensing technology foundations while serving distinct monitoring use cases in industrial, mining, and infrastructure applications.

• OptaSense (Viavi Solutions): Distributed acoustic and temperature sensing provider for pipeline monitoring, security, and oil & gas applications. Directly competes with GESO's pipeline and well monitoring offerings in international markets.
• AP Sensing: German DTS and fiber optic sensing specialist, headquartered in Böblingen. Direct competitor across pipeline leak detection, power cable monitoring, and fire detection, and also listed as a GESO technology partner. The closest like-for-like peer in product portfolio and geography.
• Bandweaver: China/UK-headquartered provider of distributed fiber optic temperature and strain sensing systems for fire detection, pipeline leak detection, and power cable monitoring. Directly competes with GESO's LDS, FireFinderM, and TMS product lines.
• Roctest (RST Instruments): Canada-based provider of geotechnical and structural monitoring instruments, including fiber optic sensors, for dams, tunnels, mines, and pipelines. Directly comparable to GESO's FBG-based SMS platform and TMS for hydraulic engineering and geotechnical applications.
• Luna Innovations: US-listed fiber optic sensing company (parent of Silixa and OptaSense) offering DTS and FBG-based distributed sensing for oil & gas, infrastructure, and defense applications. Direct competitor across the full DTS/FBG stack.

Broad incumbents

• Schlumberger (SLB): Global energy services giant with downhole fiber optic monitoring and DTS offerings through its Well Construction and Production segments. Competes in the same underground gas storage and well integrity monitoring space but with much larger scale and global reach.
• Halliburton: Global oilfield services major offering downhole monitoring and fiber optic sensing solutions (via its Well Construction and Completion product lines). Overlaps with GESO's CementationControl and StorageControl offerings for well integrity and storage monitoring, but as part of a vastly larger portfolio.
• Yokogawa Electric: Japanese industrial automation and measurement incumbent with a DTS product line (DTSX) used for pipeline and well monitoring. Competes with GESO as part of a much broader industrial automation portfolio rather than as a niche specialist.
