Abstract
Composition of matter in the present invention relates to the application of a synthetic hydrocarbon compound, such as a polyalphalolefin, which may be combined with emulsifiers and thinners (functional additives), at a ratio of approximately 9:1, to serve as a downhole lubricant which is non-toxic and presents no destruction to marine life. In addition, the polyalphalolefin may be used at a higher ratio of the polyalphalolefin to functional additives, to function as a spotting fluid for the removal of lodged tools downhole, exhibiting the same non-toxic qualities as when it is utilized as a lubricant.
