Drilling, completion, extraction, downhole operations and surface gathering expose equipment to high temperatures and pressures, hydrogen sulfide and other corrosive gases, seawater and mineralized water, heavy friction and abrasive sand. Bearings, valves, threads, wire ropes and drives can wear, corrode, leak or seize, increasing costs, downtime and operating risks. General-purpose greases often lack the necessary corrosion, temperature and media resistance. SEIVIO's application-specific solution matches lubricants to oilfield equipment and operating conditions.
Four challenges dominate: corrosive attack from downhole hydrogen sulfide, carbon monoxide, acidic or alkaline mineralized water and seawater; high-temperature/high-pressure coking and lubricant loss in deep-well and wellhead equipment; heavy-load and vibration wear in drilling drives and lifting ropes; and inadequate compatibility between lubrication and sealing in threads, valves and cable pressure-control points. SEIVIO formulations emphasize corrosion resistance, temperature capability, extreme-pressure protection and resistance to media washout.
Developed for hot, pressurized, corrosive downhole service, LT20 resists acidic media, moisture and coking, including exposure to hydrogen sulfide, acid gases and mineralized water. It serves downhole drilling and production tools, LPG systems, internal valve parts in wellhead water-injection systems, mechanical seals, oil seals and sliders. A stable protective film in wet, corrosive environments helps prevent valve sticking, rust and wear during continuous operation.
A fully synthetic high-temperature base oil and specialty extreme-pressure additives provide low friction, antiwear performance, sealing and chemical stability. It protects tubing, casing and line-pipe threaded joints against scuffing, wear and loosening while sealing clearances against oil and gas leakage. Also suitable for fiberglass casing threads, it resists hydrogen sulfide and remains in place under high temperatures and pressures during completion and pipeline installation.
Water, rust and wear resistance suit outdoor and offshore production exposed to rain, seawater and sand. Applied to wire ropes and heavy cables in oilfield winches, drilling cranes and lifting equipment, it penetrates rope clearances and forms a tough film to reduce interwire friction, corrosion, broken wires and aging. It extends rope life in open-air, humid and salt-spray environments.
Designed for low-speed, heavy-load and high-vibration applications, it offers tackiness, throw-off resistance, long maintenance intervals and extreme-pressure capacity. It serves open gears, worm drives, reduction gears and conveyor drives in drilling equipment. It counters vibration-induced grease loss under shock loads and continuous operation, reducing wear, noise, stoppages and maintenance frequency.
Free from solid additives and resistant to coking and hardening, L211 offers high-temperature performance and a service life 3-5 times that of ordinary high-temperature grease. It serves hot surface equipment, wellhead high-temperature bearings, medium-speed heavily loaded drives and precision moving mechanisms. Stable lubrication under sustained heat prevents sticking from carbon deposits and coking.
Matched grades cover downhole equipment, thread sealing, rope protection, hot drives and valves while combining lubrication, sealing, rust prevention and antiwear functions. They reduce wear, corrosion and leakage, extend equipment life and limit replacement and downtime costs. Chemical stability and resistance to oil, gas and acidic or alkaline media support land, offshore and deep-well production, contributing to lower costs and stable operation.
