Sand in produced oil and gas can cause severe erosion damage. A multitude of factors affect erosion severity. An approach which can consider most of the factors and accurately quantify the amount of material loss is of great significance for oil and gas producers to prediction erosion for oilfield geometries like sudden contractions and expansions. Previously, a comprehensive CFD-based erosion prediction procedure has been proposed at Erosion Corrosion Research Center (E/CRC) based on a systematic study of erosion for abrasive jets. The procedure has provided engineers with a powerful tool to conduct erosion study and derive the optimal operating conditions. Application and validation of this procedure for sudden contractions and expansions in this work further demonstrates the generalization and robustness of this CFD-based method. Limitations of current CFD codes for erosion simulation of these geometries have been also highlighted in the process. Attempts to overcome the limitations are discussed. Finally, insights of running erosion simulation utilizing CFD for such geometries are summarized.
