Oil casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas
wells or wellbore.
It is inserted into the well bore and cemented in the well, protect both subsurface formations and the
wellbore from collapsing, allow drilling fluid to circulate in it and extraction to take place.
