11-3/4" API 5CT CASING
Exploration OCTG Casing 11-3/4" Well Bore Inserted 114-508 Mm Outer Diameter 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 a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
