•Hydro Testing Pipelines
Primary cementing is cement work performed during the drilling phase of
the well to provide zonal isolation, casing support and protection of the
pipe from corrosive fluids.

This is performed by circulating a cement slurry through the inside of the
casing and out into the annulus through the casing shoe at the bottom of
the casing string. In order to precisely place the cement slurry at a
required interval on the outside of the casing, a rubber or wooden plug is
pumped with a displacement fluid behind the cement slurry column, which
"bumps" in the casing shoe and prevents further flow of fluid through the
shoe. This bump can be seen at the surface as a pressure spike at the
cement pump.
To prevent the cement from
flowing back into the inside of
the casing, a float collar above
the casing shoe acts as a
check valve and prevents fluid
from flowing up through the
shoe from the annulus.
