OCTG - Well Casing for Oil Wells

Well 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.

There are five different types of well casing. They include:

(Click any of the above for its description.)

Careful planning is required so that the proper casing for each well is installed. Subsurface characteristics, the diameter of the well, and the pressures and temperatures experienced throughout the well, are all taken into account when planning the various casing strings.
