Abstract
The University of Tulsa Erosion/Corrosion Center (E/CRC) has developed a mechanistic model that predicts maximum penetration rate and erosion ratio for different pipe geometries using a one-dimensional approximation approach. The model, which is called 1-D Sand Production Pipe Saver (1D SPPS), considers the effects of particle properties (shape, size, and density), fluid properties (density and viscosity), flow speed and geometry (pipe size and geometry). A user-friendly computer program using the 1D SPPS model is available to member companies of TU E/CRC, and it is currently used by Chevron for erosion predictions in different pipe geometries. Although 1-D SPPS is designed to be conservative, there is no quantitative information regarding how conservative the predictions are. Furthermore, it has been suggested that 1-D SPPS may generate optimistic erosion-rate estimates for some operating conditions. This project aims to develop approaches for quantifying the uncertainty of 1-D SPPS predictions.
