The production of gas and oil is often accompanied by water, either from the formation, from condensation, or from water injected as lift assist. Acid gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2) are often present in produced fluids, and oxygen is sometimes a contaminant in the water used for injection. These acid gases increase the corrosively of the waters to steel, and can significantly impact the safe operating life of production tubular and equipment, production vessels, and transportation systems.
The presence or absence of multiple phases (gas, water, and oil or condensate) in the same system can complicate the problem of controlling corrosion. The flow regime or pattern of fluids in a tubing string, vessel, or pipeline can have a significant impact on corrosivity. If a well or pipeline experiences "slug" or intermittent flow, highly corrosive conditions may exist in the area of the pipe in slug flow.
Pipelines can experience top-of-line corrosion when conditions promote the rapid condensation of water in a cooler section of the line, causing a film of water to form at the top of the line. This water at the top of the pipe becomes saturated with acid gases and corrodes the pipe. A further complication is a change in conditions, such as flow rate, temperature, and pressure over the life of a well, production or processing system, or pipeline, which can result in changing corrosivity or even a change in the potential corrosion mechanisms.
The control of corrosion in the oilfield can be a complex problem, requiring detailed analysis and a thorough understanding of the range of conditions expected during the life of the system prior to the development of a corrosion management plan. RIMPRO CORROSION INHIBITOR product line consists of a number of corrosion inhibitor formulations - some have been developed to address specific corrosion problems and others have been formulated to have wide applicability. RIMPRO inhibitor products are proven performers with a solid history of "raising the bar" in providing cost-effective corrosion protection in all oilfield operations. Applications include controlling corrosion in all types of oilfield operations, including oil and gas production, processing, and transportation systems.
Corrosion inhibitors react with the metal surface to form an impermeable film layer on it to stop galvanic corrosion through the reactions of produced oilfield materials and exploring equipments as well transporting pipe network. The organic base corrosion inhibitors or aqueous form work well in high-low temperatures or any kind of environments helps to improve the performance and efficiency of oilfield machineries with decreased down time. These specialty chemicals are the best practices to reduce the detrimental corrosion effects on oilfield plants and exploration-carrying devices.
Amine based inhibitors act by forming a persistent film on the drill hole piping and general oil handling equipments such as tanks and inhibits corrosion resulting from hydrogen sulfide and organic acids in the oil field. Organophosphate inhibitors are water soluble formulations used for general prevention of oxidation on metal surfaces. They are particularly effective in preventing erosion resulting from the oxidation process of oxygen. This type can be added to agitating muds of the oil wells for protection of the equipment. Organic inhibitors are formulated to function under high temperature and high pressure gas and oil production machines.
Formulating an effective corrosion inhibitor is a complex task. Laboratory and field-testing are often required for development of a corrosion inhibitor. The first step in formulating a corrosion inhibitor is determining the inhibitor's intended application in the oilfield production system.
