Abstract
The present invention addresses to a system that aims at reproducing situations close to those found in oil wells, in relation to the thermodynamic conditions (pressure and temperature), and the fluids present (by means of the chemical species involved), aiming at representing in a more realistic way the production scenarios to be faced. The main scope is to represent on a laboratory scale the phenomenon of depressurization with the release of carbon dioxide inducing the precipitation of calcite (calcium carbonate), the growth and agglomeration of inorganic crystals, and the phenomena of adhesion and scale on common metallic surfaces of elements of completion of oil wells.
