Title: A METHOD AND SYSTEM FOR DELIVERING A DRAG REDUCING AGENT
Abstract:
The present disclosure relates to a method for reducing drag in a pipeline transporting a fluid originating from a subterra-nean 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 injec-tion pipeline and transported into contact with the fluid origi-nating from a subterranean formation flowing in riser flow line.
