This paper proposes a numerical solution for the calculation of the downhole dynamometer card for deviated wells equipped with sucker-rod pumping. The solution shown is based in the model developed for the project of sucker-rod pumping systems considering three-dimensional trajectories. The results shown indicate that the incorporation of the three-dimensional model to the algorithm allows the adequate calculation of downhole dynamometer cards for vertical and deviated wells. The model enables the estimation of important productive parameters for any sucker-rod pumping system, such as flow rate and intake pressure, besides calculating significant data for deviated systems, such as lateral load acting throughout the rod string.
