Abstract
During the secondary recovery process, due to the incompatibility between formation and injected water, precipitation of inorganic salts, as the calcium carbonate, can occur. The salt are usually cared with the flow and it can reach the well equipment, as the sand control screens. The deposition of the inorganic salt can act reduce the flow area, increasing the pressure drop, or completely obstruct the fluid passage. Using correlations available in the literature and elaborating a sub routine, this paper model the influence of the calcium carbonate incrustations on the pressure drop in sand control screens. The control devices were treated as porous media, with an additional source term to model the pressure drop due the particle deposition. The results show the locations where the material depositions tend to occur and their influence on the increase of the pressure drop with the calcium carbonate incrustation.
