Casing

Casing is an integral part of the oil drilling and completion process.

In general, casing provides structure and strength to the walls of the well hole so that it doesn’t collapse on itself. It also ensures that there is no seepage of oil or natural gas out of the well hole as these are brought to the surface.

Casing is large diameter pipe that is assembled and inserted into a recently drilled section of a borehole and typically held in place with cement.
