1. A method of servicing a wellbore, the method comprising:
introducing, into a subterranean zone, a wellbore fluid comprising:
a lubricant composition comprising a vegetable oil comprising soybean oil; a non-ionic surfactant;
and a degreasing agent comprising ethyl lactate,
wherein the lubricant composition comprises from about 80 to about 95 weight percent (wt %) of the vegetable oil based on a total weight of the lubricant composition, from about 10 to about 15 wt % of the degreasing agent based on the total weight of the lubricant composition, and from about 0.1 to about 5 wt % of the non-ionic surfactant based on the total weight of the lubricant composition.
