Well casing

Well casingA well casing is made up of a series of steel tubes placed in an oil or gas well as the drilling and completion process moves forward. There are five different types of well casing:

  • Conductor Casing,
  • Surface Casing,
  • Intermediate Casing,
  • Production Casing,
  • Liner String

How it’s important to us

Casings are used to strengthen the wall of a well (keeping it from caving in during drilling) and to prevent it from blowouts. In addition, they serve as conduit for fluids movement and control.
