For over 30 years glass reinforced epoxies (GRE) have proven to outperform other polymers in protecting tubulars from corrosion and abrasion.
Corrosion in the oilfield can be caused by many sources: H2S, CO2, dissolved oxygen, brinish disposal water, highly acidic soil conditions and many others. Corrosion reduces productivity, and causes downtime for maintenance, or worse, replacement. Each year, corrosion costs oil and gas operating companies billions of dollars in lost revenue and reduced operating profit.
Operating companies involved in oil and gas production have to abide by safe and timely production schedules. In many instances, fluids are so highly corrosive that most tubulars will experience greatly diminished life cycle without some sort of protection.
There are ways to minimize the effects of corrosion on the internal surface of oilfield tubulars. The two most commonly used forms of protection are coatings and liners.
Overall, GRE liners have solved the problem faced by other tubular corrosion control options. GRE lining systems have a proven track record in a great number of demanding environments including water injection, CO2 injection, gas production, gas-lifted oil production and chemical disposal wells, onshore and offshore. They have outstanding performance history in harsh environments containing CO2 and H2S. GRE liners have successfully prevented corrosion in gas production wells with high temperatures.
GRE liners from Duoline® Technologies are manufactured with a filament winding and high temperature cure process. See Protecting oilfield tubulars against corrosion to learn more about how GRE composite liners can help solve the problem.
