Applications ## Engineered for the world's most demanding wells Exploration & Production ### Production tubing and casing widely used and tested in the most demanding exploration and production wells. CRA tubular solutions are designed and proven for highly corrosive, HP/HT and deepwater oil & gas wells, where material selection, connection performance and long-term well integrity are critical. SENTINEL® Prime has been specifically designed and tested on CRA materials to withstand these extreme operating conditions. Talk to our team Enhanced Oil Recovery & Water Injection ### Engineered for high-pressure water injection in demanding reservoir conditions. CRA tubular solutions provide enhanced resistance to chloride-induced corrosion, pitting and stress corrosion cracking in seawater and treated-water injection environments. Using duplex, superduplex and nickel-based alloys, TBX Nexxia helps ensure reliable injection performance, long-term well integrity and reduced lifecycle costs in EOR operations. Talk to our team Carbon Capture, Utilization and Storage ### TX25NP-125 Super Duplex and SENTINEL® Connections, tested for CO₂ injection with impurities. SENTINEL® Connections have been tested as per specific CCUS well conditions, including cryogenic thermal and pressure cycling. Talk to our team Geothermal Wells ### Duplex stainless steels and nickel alloys built for extreme temperatures and aggressive brines. High-performance duplex stainless steels and advanced nickel alloys with superior resistance to stress corrosion cracking, pitting and localized erosion, maintaining strength and integrity at elevated temperatures. Talk to our team Acid Gas Injection ### Duplex and nickel alloys engineered for injection environments with high concentrations of H₂S and CO₂. Using advanced duplex stainless steels and nickel alloys with tightly controlled microstructures, TBX Nexxia delivers reliable pressure containment, long-term integrity and enhanced resistance to SSC and HIC.
