Casing

Oil Country Tubular Goods

Casing is used to describe Oil Country Tubular Goods (OCTG) or API steel pipe that becomes part of a completed oil and gas well. The term "casing" applies to pipe that is used to line the drilled hole to protect the well from formation fluid flow or collapse. The ability of casing to perform properly depends on the physical integrity of the pipe body and connections (threads).
