Asset Integrity

Tailored SUEZ solutions to maximize asset integrity

SUEZ's comprehensive Asset Integrity chemical and engineered solutions, together with years of expertise, allows us to offer site-specific solutions to effectively address corrosion, bacteria, hydrogen sulfide and other challenges that are a concern. Produced water in the system is the main cause of corrosion in the piping and vessels and the situation is compounded by the presence of acid gases associated with the hydrocarbons. De-aerating oxygen from the injection water is essential to mitigate corrosivity and protect injection networks.

SUEZ's Prosolv* family of chemical solutions lead the way in corrosion, sulfide, biocide and oxygen scavenger treatment technology.

Corrosion Inhibitors

In oil & gas production, corrosion ranks as one of the top cost drivers. There are many factors that contribute to corrosion, some of which are easily controlled, some that are seemingly impossible to control. A combination of factors contributes to this issue including brine chemistry, bacteria and related byproducts, gas composition, oxygen encroachment, temperature and pressure conditions, use of dissimilar metals, fluid flow conditions, solids (abrasion), electrical charges, chemicals and additives used to stimulate production, and more.

Hydrogen Sulfide Scavengers

A major production challenge in oil & gas systems is the presence of Hydrogen Sulfide (H2S). H2S may be present in the reservoir "naturally" or it may be due to the presence of sulfate reducing bacteria (SRB) which produce hydrogen sulfide. H2S is highly reactive, especially with iron, and in most systems the H2S will readily react with iron in ionic form or iron from metal surfaces, to form various species of iron sulfide (FeS). SRB colonies adhering to pipe walls can become iron sulfide factories, eating away at the pipe surface and forming pits which eventually may cause leaks and failures.

Biocide and Biogrowth Control

Bacterial contamination of oil & gas production systems is a serious production challenge requiring the right chemistry and application methods to properly control. Bacteria may have been introduced in many ways and over many years - drilling well completions, reinjection of produced waters for pressure maintenance, EOR projects, workovers, hot oil/water treatments, etc. It's often impossible to determine the cause, but once bacteria take up residence in your reservoir or production system, they are difficult to eliminate. The good news is that with SUEZ's chemical treatments, bacteria-related issues can be controlled and production issues minimized.

Oxygen Scavengers and Oxygen Inhibitors

Oxygen is a serious threat to system integrity, even at extremely low amounts. Most oxygen corrosion is directly attributable to addition of fluids which have been exposed to fresh air. Oxygen can be introduced during fracs, waterfloods, squeezes and workovers when large volumes of fluids are injected downhole. On the surface, loose fitting valves and connections, pinhole leaks, or tank openings can allow the oxygen to enter lines, reacting with system metallurgy.
