Engineered for high-temperature, high-pressure, and corrosive environments in geothermal and offshore drilling fields across the Netherlands.
The Netherlands is undergoing one of the most aggressive energy transitions in Europe. Following the decision to phase out natural gas production from the historic Groningen field, the country has turned its focus toward sustainable heating alternatives. Deep and ultra-deep geothermal energy (Aardwarmte) has emerged as a cornerstone of this transition, aimed at decarbonizing municipal district heating networks and the massive Dutch greenhouse horticultural sector.
Geothermal wells in regions like Westland, North Brabant, and South Holland are drilled to depths ranging from 2,000 to over 4,000 meters. Monitoring these deep wells requires highly specialized downhole logging cables. These cables must transmit critical real-time data regarding temperature, pressure, and acoustic signals to ensure well integrity, optimize heat flow, and detect potential seismic activity. As a leading global supplier, Huaneng provides advanced fiber optic and copper logging cables that serve these precise needs.
Ultra-deep geothermal monitoring, offshore gas field decommissioning in the North Sea, and carbon capture and storage (CCS) projects such as Porthos and Aramis require resilient logging cables that can withstand corrosive saline aquifers and high pressure.
Huaneng company has been focusing on cable manufacturing for more than 50 years and we are the industrial standard constitutor of wireline logging cable and optical fiber wireline logging cable in China. We have 183 employees and cover an area of 80,000 square meters, housing China’s most technologically advanced and largest-scale manufacturing base for wireline logging cable and optical fiber wireline logging cable.
By constantly innovating and upgrading our production facilities, we deliver high-performance cabling solutions that support deep-well diagnostics and continuous monitoring. Our products are widely deployed in challenging geological environments worldwide, offering Dutch operators a reliable supply chain for critical projects.
Operating in the Netherlands presents unique geological and environmental challenges. The Dutch subsurface contains highly saline aquifers, which can accelerate the corrosion of standard metals. When downhole logging cables are deployed in these wells, they are exposed to chloride-induced stress corrosion cracking (SCC). To prevent premature cable failure, Huaneng utilizes premium corrosion-resistant alloys for cable armoring, such as 316L stainless steel, Alloy 825, and super duplex steel wire wrappers.
Furthermore, the industry is shifting rapidly toward distributed fiber optic sensing (DFOS). Technologies like Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) have become standard for monitoring injection and production profiles in Dutch wells. Rather than relying on periodic logging runs, operators permanently install fiber optic logging cables to capture continuous, real-time profiles of the entire wellbore. This allows for immediate detection of thermal breakthroughs, casing leaks, and cross-flow issues, minimizing downtime and maximizing the operational lifespan of geothermal district heating plants.
Since 1997, through technology introduction, digestion, absorption, and re-innovation, Huaneng company has achieved a perfect transformation from industry followers to industry leaders.
Relying on the development soil provided by domestic and international energy exploration companies, we have broken the technical barriers that the load-bearing detection cables used for complex well conditions must be imported. By keeping a strict pursuit of product quality for over 50 years, we provide the best quality and cost-effective products for the field of energy exploration and development. While manufacturing high-quality products, Huaneng puts service into our focus, which aligns with our core value concept of "Produce High Quality Products, Provide Wholehearted Service". Huaneng has more than 50% percent market share in China and we are committed to becoming a global leader in wireline logging cable and optical fiber wireline logging cable.
