ABSTRACT:
A wellbore fluid (e.g., a drilling, completion, packer, or fracturing fluid) comprises (a) at least one additive selected from the group consisting of emulsifiers, wetting agents, viscosifiers, weighting agents, fluid loss control agents, proppants for use in hydraulically fracturing subterranean formations, and particulate agents for use in forming a gravel pack; and (b) a non-toxic white mineral oil having (i) an API gravity at 15.6.degree. C. (60.degree. F.) greater than 35, (ii) a content of compounds containing 14 or more carbon atoms of at least about 95 weight percent, and (iii) a pour point of at least about -30.degree. C. (-22.degree. F.).
