WIRELINE LUBRICANT FOR USE IN GREASELESS DOWNHOLE LOGGING
A rubber friendly lubricant composition adapted for lubricating the cable in a greaseless down hole logging process including a general formulation: polypropylene glycol, poly alkylene glycol; amine borate; 1,3,4-Thiadiazolidine-2,5-dithione, disodium salt; and, deionized water. The lubricant being compatible with seals and rubbers, and other related materials, used on trucks and other oil field vehicles and equipment. Being water soluble, the lubricant also presents a low potential for fire risk, and is considered environmentally friendly. The lubricant also exhibiting superior freeze properties.
Compositions containing difluoromethane, tetrafluoropropene, and carbon dioxide and uses thereof
In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf, and CO.sub.2.
