Abstract
One of the concerns regarding the development of the Brazilian pre-salt cluster is due to scale issues. The huge carbonate reservoirs have a high potential for salt adhesion due to the precipitation of the crystals from the solution along with the production tubing as well as at the internal surface of the entire completion system. This paper presents a methodology for enhancing scale prediction studies applying Computational Fluid Dynamics (CFD) techniques to describe the fluid flow through a completion accessory. Then, an Euler-Lagrange approach is applied to simulate the transport of the crystals toward the adhesion surface. This approach coupled the CFD study to the Discrete Phase Method (DPM) and aims to estimate the scale rate at a Sliding Sleeve valve used as Inflow Contol valve (ICV) in a well completion environment. The scale is modeled using the critical velocity of adhesion criterium, implemented in a user-defined function to modify the DPM boundary condition.
