Overview
Well sites and gas plants are unmanned and remotely operated, and consequently only a limited number of operators stay on site. Oil wells need real-time and cost-effect communication systems to monitor operations from the wellheads and separator stations from the SCADA control center.
Most onshore well sites are scattered across a vast region with difficult terrain and adverse environmental problems such as corrosion, temperature extremes, and risk of explosions. For this reason, most onshore network devices must be industrially hardened and compliant with the ATEX directive to ensure operating success and safety. 
Solution
TNS Gigabit managed Ethernet switches can form Gigabit fiber redundant rings and uplinks to provide transparent information from wellheads to the SCADA control center, and also enable real-time video, audio, and data transmission from various well sites. Network management systems allow you to supervise your Ethernet networks with a simple web browser.
TNS offers a complete line of IP video surveillance solutions that includes video encoders, video decoders, and IP cameras. With particular emphasis on industrial design, intelligent features, and advanced compression technology, TNS video-over-IP solutions provide a broad range of choices for remote wellhead monitoring.
TNS Products have rugged features for system reliability; dual redundant power; -40 to 75˚C operating temperature; single-mode or multi-mode fiber optic support. The products are also certified by Ul/cUL Class I, Division 2, Groups A, B, C, and D & ATEX ClassI, Zone 2, Ex nC IIC.
