Abstract
A lubricant composition includes (a) a hydrocarbon oil including at least 30% wt of isoparaffins, based on the total weight of the hydrocarbon oil, and (b) an alkoxylated natural oil. A method of using the lubricant composition in a water-based composition, in particular a water-based mud, to improve the lubricity and/or to reduce the foaming properties of the water-based composition is also disclosed.
Claims20
A lubricant composition comprising:
- (a) from 0.1 to 40% wt of a hydrocarbon oil comprising at least 30% wt of isoparaffins, based on the total weight of the hydrocarbon oil, wherein the hydrocarbon oil is a hydrocarbon fraction having an initial boiling point and a final boiling point in the range of 230° C. to 340° C.;
- and
- (b) from 60 to 99.9% wt of an alkoxylated natural oil,
- based on the total weight of the lubricant composition,
- wherein the hydrocarbon oil has a flash point equal to or higher than 110° C.

A lubricant composition comprising:
- (a) from 1 to 10% wt of a hydrocarbon oil comprising at least 30% wt of isoparaffins, based on the total weight of the hydrocarbon oil,
- (b) from 65 to 80% wt of an alkoxylated natural oil, and
- (c) from 10 to 30% wt, of a non-ionic surfactant,
- based on the total weight of the lubricant composition,
- wherein the hydrocarbon oil has a flash point equal to or higher than 110° C.
