Liquid-O-Ring 766 CO2Resistant Wireline Grease Seal is formulated to protect wireline cable from the corrosive effects associated with carbon dioxide (CO2) operations. The problems associated with hydrocarbon-based material exposed to CO2necessitated the development of a wireline grease seal resistant to these adverse conditions.Liquid-O-Ring 766 CO2 Resistant Wireline Grease Seal is manufactured with totally synthetic materials (Polydimethyl Siloxane) inherently resistant to CO2 and H2S. It provides the desired seal, adhesion, and lubrication properties favorable to wireline operations exposed to a CO2 environment.
Liquid-O-Ring 766 CO2Resistant Wireline Grease Seal is more resistant to viscosity change with varying temperatures than hydrocarbon-based wireline products. Liquid-O-Ring 766 CO2 Resistant Wireline Grease Seal is available in 10, 12, 16, 20, 24, and 28 viscosities, having a density of 1 g/ml @ 24 viscosity.
Liquid-O-Ring 766 CO2 Resistant Wireline Grease Seal recommended applications include grease injection control heads in CO2 operations and cable lubricators.
BENEFITS:
▪ Inert and not affected by CO2 and H2S commonly found in wells
▪ Resists corrosive effects of other downhole chemicals
▪ Less viscosity change with temperature
▪ Low surface tension
▪ Chemically inert
▪ Excellent oxidation and thermal stability
▪ Increases wireline life
▪ Economical
