PROTECTION OF CASING FROM CORROSION

Casing can be protected by one or a combination of the following:

• Using wellhead insulator (electrical insulation of well casing from the flow — line).

• Cementation (placement of a uniform cement sheath around casing).

• Placing completion fluids around casing which has not been cemented (these fluids should be oxygen-free. high-pH and thixotropic).

• Cathodic protection.

• Steel grades.
