Abstract: Integrated method for evaluating and mitigating formation of calcium carbonate scales in oil and gas well completion systems. Pertaining to the field of oil engineering, the methodology combines computational fluid dynamics (CFD), thermodynamic and kinetic models, allowing the simulation and prediction of behavior of scales under complex operating conditions. The method has five main steps: collection of geometric and operational data; generation of velocity and pressure profiles; calculation of the crystal deposition rate; thermodynamic and kinetic simulation of the precipitation and scaling processes; and calculation of a scale index that quantifies the risk associated with each piece of equipment and completion. The methodology assists in identifying critical points, optimizing designs, and reducing operational costs, ensuring greater efficiency and reliability in offshore environments.

Abstract: The present invention relates to a system and method to be applied to multiple inflow and outflow control zones in an open-hole uncoupled completion. The invention can handle, for example, the complexities and limitations of hydraulic control found in carbonate reservoirs in the Brazilian Pre-Salt, which are characterized by high pressures and flows, large vertical extensions of the reservoir, high scaling potential, and high potential for losses during drilling and completion operations.
