Completion Tubing - Material Selection
Material selection is determined by the abrasion and corrosion properties of the fluid, the pressures and the mechanical and hydraulic loadings on the completion string under operating conditions, e.g. stimulation, injection and production conditions.
Tubing stress calculations will allow specification of threaded coupling type, and material as well as identifying the need for a dynamic seal assembly to accommodate tubing movement.
There are six distinct material groups which are used in well applications:
- Low alloy steels
- Medium-alloy steels
- Stainless steels
