Zusammenfassung:	Ether amines, or salts thereof, are proposed for use herein as lubricity additives for drilling fluids. Methods for wellbore operations and for improving lubricity include adding an ether amine to the drilling fluid. The ether amine is represented by the general formula: where R1 is represented by the general formula: where R5 is a straight chain, branched, or cyclic aliphatic radical with about 3 to 20 carbon atoms; X is 0 to 10; R2 is a straight chain, branched, or cyclic aliphatic radical with about 3 to 20 carbon atoms; and R3 and R4 are each one of H or a straight chain, branched, or cyclic aliphatic radical.
