CO₂ Injection and Water Injection systems are key enhanced oil recovery (EOR) and reservoir pressure maintenance methods used in upstream production. CO₂ injection improves hydrocarbon mobility and sweep efficiency by reducing oil viscosity and increasing reservoir pressure, while water injection maintains reservoir energy and supports sustained production rates. These processes require reliable pumping, flow control, and continuous monitoring to ensure safe and efficient operation. Accurate analytical instrumentation is essential to verify gas and water quality, protect injection equipment, and maintain reservoir performance. Typical monitoring objectives include oxygen and moisture control in CO₂ streams, water quality verification, corrosion risk monitoring, and flow assurance. Our solutions support injection skids, pump lubrication systems, and distribution lines with robust online analyzers and instrumentation helping operators maximize recovery, protect assets, and ensure long-term injection reliability.
