heal.abstract	The presence of hydrogen sulfide (H2S) and carbon dioxide (CO2) in oil reservoirs is concerning due to their toxicity and negative impacts on the production process. The acidic mixture resulting from their combined presence can cause alteration of the desired characteristics of the hydrocarbons produced, such as the quality of the oil. For this reason, the petroleum industry typically incorporates a stage of hydrocarbon trapping and further processing at the surface to remove these acidic components. This process is crucial for personnel safety, environmental protection, as well as ensuring the quality and performance of the produced oil. Reinjecting acidic gas from injection wells is a common practice for managing this type of gas. The purpose is to reduce the costs of processing acidic gas and maintain reservoir pressure. To effectively carry out the acidic gas reinjection process, it is essential to precisely understand the developing pressure and temperature along the injection wells. This requires a correct description of the thermodynamic behavior of the acidic fluid, as pressure and temperature affect how this gas behaves along the drilling. Only then can we take effective measures for managing and reusing acidic gas through injection wells. This thesis aims to qualitatively test the results of a commercial software, namely PROSPER by Petex, used to determine the pressures, temperatures and properties of the acidic fluid, as well as to analyse the behaviour of its phases in the whole section of the well during the injection process. For the thermodynamic description of the fluid behaviour, cubic equations of state (EoS) are used, which are available in the software mentioned. The results of the qualitative control are very encouraging. The agreement between the simulation results and the literature enhances the validity of the methodology and accuracy. However, observing the software errors in the detailed examination of the fluid's thermodynamic properties requires attention. Although these errors seem not to significantly affect the macroscopic properties of the flow such as pressure and temperature, it is important to correct them to improve the model's accuracy. This can ensure even greater reliability of the results and the application of the methodology in more practical applications.	en
