Acid Gas Injection Wells

And the Use of Corrosion Resistant Alloys

If water is present in acid gases, the conditions may be very corrosive. Low-alloy steels are commonly utilized in “dry” Acid Gas Injection wells that are designed to be “water-free”. However, low compressor discharge temperatures can cause water formation even in “dry” acid gas wells. Casing and tubing are also exposed to ground water below the packer.
While stainless steels may provide sufficient resistance to corrosion from CO2, the partial pressure of H2S in the acid gas often exceeds the limits of stainless steels. In these situations, a nickel-base alloy is recommended to adequately resist corrosion. For temperatures below 270F, 2535 has proven to be a reliable choice, while for higher temperatures 2550 is an effective option.
PipeSearch has several options suitable for these applications available for quick release.

The PipeSearch Platform consolidates update-to-date mill schedules, lead times, and global market inventory into the largest database of corrosion-resistant alloy tubulars in the world.

PipeFacts by PipeSearch is a multi-stage process that utilizes proprietary software to manage a sequence of QA/QC steps in the evaluation of OCTG. It is designed to bring transparency, integrity, and consistency to the evaluation of tubulars no matter the location of the pipe.
PipeFacts goes beyond standard physical inspections of material. It evaluates the specification of the original MTRs against API 5CRA or 5CT, identifies any exceptions, and sets a standard by which MTRs are reviewed and by which inspections are performed. Our PipeFacts process has been developed to give customers complete confidence in the product they are receiving.
