What is OCTG Tubing?
An OCTG tubing is a pipe that is placed inside the wellbore through the casing pipe. It is responsible for the transportation of the hydrocarbons to the surface. It is an oil well tubing either used for transporting natural gas or crude oil to the facilities for further processing after the drilling is complete. Similar to the drill pipe and casing, tubing also is subjected to high pressure during the extraction process and hence needs to be thick, strong, and sturdy. An OCTG tubing is used for transporting natural gas or crude oil after the drilling is complete. It transports the gas and oil to the facilities for further processing. Similar to the drill pipe and casing, OCTG tubing also has to withstand high pressure during the extraction process, and hence they are required to meet industry standards. OCTG tubings are available in various sizes ranging from 1 1/4” to 4.5”.
The tubing protects the casing from wear and tear caused by corrosive fluids, sand, paraffin, and more. In case of damage or breakage, the OCTG tubing can be easily replaced.
