Abstract
We evaluate the settling of a suspension in an annular geometry, where the concentric pipes are placed horizontally. The geometry was chosen to mimic cement slurry bleeding (i.e. accumulation of fluid on top of the geometry due to the settling of particles) in horizontal oil and gas wells. We compare the behavior of ideal semi-dilute suspensions, such as polymer beads in oil, with real cement slurries, in cells of similar geometry. Despite the differences between the two systems, our results show striking similarities and explain the presence of weak points at the upper outer diameter, below the internal diameter and at the poles.
