Cold restart of viscous multiphase flowline by hot water flushing
conference paper
The main objective of this paper is to understand the physical processes of shut-in and restart of viscous multiphase flowline. For this purpose, experiments were performed on shut-in and restart processes in the Multiphase Flow Rig at Statoil's research Centre in Porsgrunn. Real crudes were used with oil viscosity up to 30,000 cP at room temperature. Different physical processes were identified that significantly influence the shut-in and restart. The performance of the numerical tools (OLGA code and CFD) is assessed against the experimental data and theory. The OLGA code is found to predict well the shut-in process, but over-predicts the restart time. © BHR Group 2013.
