Abstract: This paper presents a comprehensive review of the theoretical and experimental studies of steady, fully-developed flow of Newtonian and non-Newtonian fluids in coiled tubing. The flow mechanisms and characteristics of secondary flow and its effect on the flow resistance have been discussed. Available friction factor correlations have been analyzed and evaluated for accuracy and applicability. Compared with its counterpart of Newtonian fluid, the flow of non-Newtonian fluid in coiled pipes has remained much less studied. The paper also briefly describes the recent development of full-scale experimental investigations on the frictional pressure losses of various fluids in coiled tubing.
