Title: An algorithm to predict pressure and temperature profiles through a coiled tubing

Abstract

The scope of this work is to develop an algorithm to predict the temperature and pressure profiles in a compressible flow through a coiled tubing, taking into account both friction losses and heat transfer simultaneously. The algorithm combines the theory of gas dynamics (heat transfer process) and thermodynamics (energy balance) to predict pressure, temperature, density, velocity and Mach number profiles for either horizontal, inclined or vertical strings. The results of the algorithm were compared with the Cullender & Smith method, which is the standard correlation used for downward gas flow calculations. A strong agreement between them was obtained. The algorithm presented allows more reliable results because it only needs for start-up, gas data that is usually very precisely known in real conditions.
