ABSTRACT:
A solids-free, essentially all-oil wellbore fluid comprises (a) an organic fluid having (i) a melting point less than about 20.degree. C. (about 68.degree. F.), (ii) a flash point greater than about 54.4.degree. C. (about 130.degree. F.), and (iii) a dipole moment greater than 0 debye (D), and (b) a salt dissolved in the organic fluid. The wellbore fluid is employed in well drilling, completion, and work-over operations.
