    Abstract: This invention relates to a composition comprising a water-in-oil emulsion formed from a brine, a liquid oil, (A) an emulsifier, (B) a friction modifier of the following formula: ##STR1## where X=1 to 4, z=1 to 6,Q=0 to 2R.sub.1 and R.sub.2 are independently H or an aliphatic group containing from 1 to about 16 carbon atoms, provided that the sum of R.sub.1 and R.sub.2 is between 0 and about 16,R' is an aliphatic group containing an average of from about 8 to about 24 carbon atoms, andR" is selected from the group consisting of H, an aliphatic group containing between 1 and an average of about 18 carbons, and ##STR2## where Q, X, z, R.sub.1, R.sub.2, R' and R" are defined as set forth above, and Y is 0 to 5. In a preferred embodiment, z is 1. In the most preferred embodiment, Q=0, R.sub.1 and R.sub.2 are both H, X, and z all equal 1, R' is n-dodecyl, and R" is H. The compositions of the present invention have beneficial lubrication properties. These compositions are useful in drilling, working and completing well bore holes.
