Acid Based Corrosion

Acid based corrosion occurs with the presence of naturally occurring acids such as Carbon Dioxide (CO2) and Hydrogen Sulphide (H2S) to name a few. 


The main method of treating this type of corrosion is by a corrosion inhibitor.  The injected corrosion inhibitor must be in physical contact with the area that requires protection.


This becomes complicated when certain well configurations have one-way valves, and packers.  Injection can be facilitated by weighted inhibitors, and capillary strings to name a few.



Common injection methods are: Batching, continuous, and pigging.  These methods can be used in conjunction with one another depending on individual circumstances.





Corrode (kə-rōd) : To eat away by degrees as if by gnawing.  To wear away, usually by chemical action.
