Some details about Casing

Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality.


Casing
Casing is the major structural component of a well. Casing is needed to:

1)Maintain borehole stability
2) Prevent contamination of water sands
3) Isolate water from producing formations
4) Control well pressures during drilling, production, and workover operations

Casing provides locations for the installation of:

1) Blowout preventers
2) Wellhead equipment
3)Production packers
4) Production tubing
