In this work our goal is to understand e simulate the gas migration in the cement slurry
during the cementing process of an annular petroleum well. The phenomenon is potentially
dangerous due to the breaching of the gas to the surface – Resulting in a Blowout. The gas
migration for the interior of the annulus occurs when the pressure inside the annulus is smaller
than the pressure inside the rock formation. Some factors that contribute for the occurrence of
this phenomenon are: incorrect density of the cement slurry, which may cause a unbalancing of
hydrostatic pressure, excessive loss of the drilling fluids, which causes empty spaces where the
gas may fill in. the numeric solution of the governing conservation equations will be obtained
through the finite volume technic and the volume of fluid method, using the commercial version
of the software Fluent (Ansys). The objective is to analyze the behavior of the gas bubble inside
the annulus, such as the factors that may affect its migration.
