Abstract
A lubricant composition containing a vegetable oil, a degreasing agent, and a non-ionic surfactant. The vegetable oil may be soybean oil, the degreasing agent may be ethyl lactate, and the non-ionic surfactant may comprise sorbitan esters, polyethoxylated sorbitan esters, or a combination thereof. Also provided is a wellbore servicing fluid containing a base fluid and the lubricant composition containing vegetable oil, degreasing agent, and non-ionic surfactant. Methods of introducing the lubricant composition and wellbore servicing fluids containing the lubricant composition into a subterranean zone (e.g., into a wellbore disposed in a subterranean formation) are also provided.
Claims20
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.
