The aim of the present paper is to describe an application developed to address the selection of materials to be used as tubing and casing in oil and gas field production facilities, based on corrosion performance. The first step is the prediction of the flow pattern and its characteristics, using a numerical model developed in house. These results are used as input to predict the corrosion rate of carbon and low alloy steels in CO2 rich environments. Additionally, the carbon and low alloy steel selection from the sour resistance point of view is carried out by following NACE MR0175/ISO 15156 part 2. The behavior of different CRAs is estimated through working windows information.
