Dear friends,
I have a doubt regarding the setting of the casing in the casing hanger after cementation is done.
After the casing lowering, cementation and WOC, the casing is hanged on the well-head via the casing hanger/slip.
Generally the procedure is that a pull equal to the weight of the casing is applied and the casing is set on that load. However, my confusion is: do we consider buoyancy for this. i.e. do we take the air weight of the casing or the buoyant weight to set the casing hanger.
Please guide.

However, if the well is vertical and as the bottom of the casing is immersed in cement, will buoyant force come into picture? Buoyancy always acts perpendicular to a surface.
