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.

Ensuring Asset Performance

To maintain operational efficiency, assets must perform required functions effectively while safeguarding against health, safety and environmental concerns. Operators can employ several strategies to prevent equipment failure, maximize oil and gas production, and significantly decreases the total cost of operation. These strategies include: site-specific corrosion inhibition mitigation, scavenging of acid gases, controlling corrosive bacteria, and monitoring tactics.

Even the most well engineering assets can face rapid deterioration when subjected to an inadequate integrity management program.

Corrosion Inhibitors

Corrosion Inhibitors for Oil & Gas

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.

The impacts of corrosion are immense. Corrosion reduces the effective life of equipment. It leads to premature failure, safety hazards, leaks, spills, fines and system shut-ins. It impacts lifting costs both by increasing the cost of operations and by reducing production revenues.

SUEZ is committed to minimizing the risk of corrosion in your production system. This is done by assessing the system and determining the root causes of corrosion, to stop corrosion in its tracks. SUEZ's process begins by evaluating the system and analyzing the production fluids and gases, focusing on mechanisms that cause corrosion. Investigating previous failures of tubulars and equipment can provide clues as to the root cause of the failure and lead to successful inhibition programs supported by monitored results.

Hydrogen Sulfide Scavengers

Hydrogen Sulfide Scavengers for Oil & Gas

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.

Left untreated, systems with H2S will generate FeS, which leads to other major operational challenges and costs because of the subsequent production issues it causes - scale, interface problems, filter and reservoir plugging, water discharge concerns, and lost production. If the water is being reused for stimulation or fracturing, the water must be conditioned to remove the FeS, which adds operational costs. If the oil or gas contains H2S above sales specifications, the production will be rejected until the spec limits are reached.

SUEZ's upstream technical team will identify the cause and extent of sulfides in your system and develop a comprehensive program to minimize the issues related to sulfides. It may involve application of a SUEZ ProSolv Hydrogen Sulfide Scavenger or a ProSolv Biocide to eradicate SRB. Rest assured that the cost-effective solution from SUEZ will address sulfides and control them so that sulfides don't control you.

ProSolv* Hydrogen Sulfide Scavengers Features & Benefits

  • Eliminate H2S and FeS in your production system
  • Reduce equipment failures and fouling
  • Prevent "black" water and related issues (plugging, emulsions, scale)
  • Improve overall safety and reduce environmental risk
  • Reduce the risk of corrosion failures and improve asset integrity
  • Meet pipeline & sales specifications all the time

By applying the right ProSolv sulfide control solution and reducing sulfide issues, hydrocarbon production will be optimized to meet or exceed your production objectives.

Biocide/Biogrowth

Biocide/Biogrowth Control for Oil & Gas

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.

SUEZ's systematic approach to bacterial control begins with assessing the locations and types of the bacteria in your system. SUEZ technical teams will sample and test fluids to quantify bacterial issues, followed by selecting solutions which attack the bacteria where they reside.

By selecting the best mitigation program, SUEZ will ensure that bacteria issues are minimized. In fracs, production and injection systems, SUEZ's ProSolv Biocides can help minimize production issues and maximize asset life. Proper control of bacteria results in reduced operational costs, reduced H2S generation, cleaner production, more efficient operations and reduced failure rates.

ProSolv* Biocide/Biogrowth Control Features & Benefits

  • Control bacterial growth in oil & gas production systems
  • Minimize microbial generation of H2S and the related downstream issues it causes, including corrosion, water quality, separation, rejected sales of gas and oil
  • Improve health, safety and environmental compliance
  • Reduce filter plugging in water injection systems

SUEZ has the know-how to deliver the knockout punch to bacteria. Specially designed formulations penetrate bacterial films and destroy the active colony. Nanofiltration systems can remove all bacteria from injected fluids, effectively providing a green solution for your water needs. SUEZ's technical teams work in collaboration with each other to deliver the optimal system to address bacterial issues in your system.

Oxygen Scavengers/Inhibitors

Oxygen Scavengers/Inhibitors for Oil & Gas

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.

At SUEZ, our field technical representatives will regularly analyze fluids to check for the presence of oxygen. If found, a thorough inspection of the upstream system will take place to identify places that oxygen enters the system. In addition, SUEZ's ProSolv Oxygen Scavengers may be applied to remove the oxygen and eradicate the corrosive risk it creates.

ProSolv Oxygen Scavengers/Inhibitors Features & Benefits 

  • React quickly with oxygen to deactivate its corrosion potential
  • Be applied in a "neat" form directly to your system
  • Provide reduced corrosion and maximize asset integrity

SUEZ's oxygen scavengers are selected to help keep your oil and gas production systems operating at peak efficiency levels. Eliminating oxygen leads to reduced failures, leaks and hazardous conditions that add costs to your operations. In addition, reduced failures lead to increases in hydrocarbon production and revenue streams.
