The present disclosure relates to a method for reducing drag in a pipeline transporting a fluid originating from a subterranean formation and to a delivery system for carrying out this method. In the method a plug flow stream is formed from at least two different fluid compositions one of which comprises a drag reducing agent. This stream is introduced into an injection pipeline and transported into contact with the fluid originating from a subterranean formation flowing in riser flow line.
