The corrosion, pressure, and temperature on an oil field can take its toll on pipe, connectors, and other OCTGs (oil country tubular goods). The oil and gas industry is a financially risky one, as the average cost of a horizontal shale wellbore can range from four to eight million dollars. To minimize risks, as well as, protect equipment investments and lives, rigorous API quality standards have been enacted. At Essentra Pipe Protection Technologies, we focus on ensuring quality standards when it comes to pipe protection. Some of these high standards and specification requirements have been listed below.
Strength, Flexibility, and Elasticity
Oil country tubular goods must be strong, flexible, and elastic to work in horizontal drilling applications. Drill strings are bent at a rate of 10-15 degrees over every 30 meters. After a 90-degree bend, the OCTGs must become straight once again.
Casings are the outer tubings that line and stabilize a wellbore and, as such, they have the strictest API requirements. After its insertion into a wellbore, casings are pressure-tested to ensure safety. The casing string’s bottom end is capped off and the drilling mud is put under intense and enduring pressure to ensure the absence of leaks.
Threaded connections turn individual tubular goods into a continuous tubing string or casing. These connections must be pressure- and strain-resistant, as well as completely gastight. Connections must be every bit as strong as the tubing they service.
Oil Country Tubular Goods Made with Specific Techniques
To work properly, OCTGs should be highly resistant to corrosion. Pipe that is strong enough to be used in gas and oil drilling cannot be made with standard thermomechanical methods, and manufacturing techniques are specifically designed to provide strength in the finished product.
Alloys Make a Stronger OCTG
Oil country tubular goods are made stronger and more reliable with the use of certain elements in the manufacturing process. Known as alloying, this supplementation process is used in conjunction with heat treatment to improve OCTG corrosion resistance.
