Abstract
AbstractCoiled tubing (CT) is used as a cost-effective means of servicing wells for well intervention. Over the years, the fluid flow through CT has been discussed and theorized. Testing has been conducted to promote a better understanding of what happens inside the CT. In recent years, the use of computational fluid dynamics (CFD) software has provided greater insight into actual CT flow patterns, including fluid-flow velocity profiles, secondary flow regimes, and erosion. CFD helps to understand the CT fluid flow phenomenon, which can lead to effective tubing management. CFD has proven to be an effective alternative to full-scale testing.This work compares the results of CFD modeling of erosion to actual field data. It compares predicted values, actual values, and computed values from the CFD solutions. CFD is used to provide correlations for the predictive model without full-scale testing, which greatly reduces the cost of development. Fluids investigated include slurry pumped from an actual job and full-scale testing.
