Abstract: Abstract We study the effect of borehole ovalization and large-scale irregularities during primary cementing of a horizontal section of well. We use a two-dimensional gap-averaged model that can compute the displacement within varying annular geometries:… read more here.

DOI: 10.1063/1.5056169
Abstract: There is a widely popular perception in the cementing community that the turbulent regime should be used where possible in primary cementing of oil and gas wells. We conduct a detailed numerical study and analyze… read more here.
