A drilling fluid composition comprising a mixture of a brine (A) an emulsifier, and (B) an oil soluble friction modifier of the following formula: [Figure] where X=1 to 4, z=1 to 6, Q=0 to 2 R1 and R2 are independently H or an aliphatic group containing from 1 to about 16 carbon atoms, provided that

A drilling fluid composition comprising a mixture of a brine (A) an emulsifier, and (B) an oil soluble friction modifier of the following formula: [Figure] where X=1 to 4, z=1 to 6, Q=0 to 2 R1 and R2 are independently H or an aliphatic group containing from 1 to about 16 carbon atoms, provided that the sum of R1 and R2 is between 0 and about 16, R′is an aliphatic group containing an average of from about 8 to about 24 carbon atoms, and R″is selected from the group consisting of H, an aliphatic group containing between 1 and an average of about 18 carbons, and [Figure] where Q, X, z, R1, R2, R′and R″are defined as set forth above, and Y is 0 to 5 is disclosed. The compositions of the present invention have beneficial lubrication properties. These compositions are useful in drilling, working and completing well bore holes.
