... system for straight pipe. Drag reductions as high as 81% were achieved in the straight pipe, and as high as 69% in coiled tubing. The heavier brines generally required greater polymer loadings in order to achieve substantial drag reduction. Field applications of the new polymer have been conducted...

... published their results for fluid flow through coiled tubing but only a limited number of studies have been reported related to temperature and salinity effects on drag reduction in fluids flowing through coiled tubing. This paper discusses experimental study of two commonly used drag reducers ASP-700...

... of larger sizes as well as coiled tubing are very scarce. Furthermore, previous studies have correlated drag reduction behavior of these fluids only through simple power-law parameters. Little is known regarding the importance of elasticity on drag reduction of SBF. Scale-up factor is yet another problem...

... The objective of this paper is to present the new experimental results of coiled tubing curvature on the drag reduction behavior of polymeric fluids in coiled tubing. Experimental Experimental Setup The experimental setup used in this study is illustrated in Fig. 1 . The flow loop...

... Abstract The excessive friction pressure loss due to the small tubing diameter and the curvature (which believed to cause secondary flow) of coiled tubing (CT) often limits the maximum obtainable flow rate in CT operations. This paper presents an experimental study of drag reduction performance...
