Frictional pressure drop along the completion is an important factor in the design of horizontal wells. It must be accounted for in order to secure optimum reservoir drainage and to avoid overestimation of the well productivity. Many authors have previously addressed various aspects of this problem, but an explicit analytical solution for turbulent flow in wellbore has not so far been published. This paper presents such a solution based on the same assumptions as those of previous researchers. © 2010 Elsevier B.V.
