Introduction. Casing and cementing are essential to drilling oil and gas wells. Lining a hole with casing keeps it from caving in after it is drilled, sealing the wellbore from encroaching fluids and gasses. Cementing the casing in place ataches it firmly to the wellbore wall and stabilizes the hole.
