... flow through the ICD dominates the pressure drop, leading to a density controlled flow. This is fortunate as density varies much less than viscosity over the production life of a field. Due to the inherent non-linear nature of a production system, the pressure drop versus flow rate will vary...

.... It is known in the industry that pipe movement helps improve hole cleaning and cement-slurry placement. However, the quantitative effect of pipe rotation on hole cleaning and cement-slurry placement for a given eccentricity, flow rate, and geometry was not well studied. Hence, it was difficult to design...
