- Casing and tubing can also be known as OCTG in the oil and gas industry.
- OCTG is the abbreviation of Oil Country Tubular Goods, it mainly refers to the piping products that are applied in oil and gas production (drilling activities). OCTG pipe is normally manufactured based on API or related standard specifications. It could also be taken as a collective name for Drill pipe, Steel Casing Pipe and Tubing pipe, Couplings, Connections, and Accessories, used in petroleum industries both onshore and offshore.
- OCTG are new and used pipe products, such as casing, tubing, drill pipe, line pipe, structural pipe, and more, which are used in the production of oil and gas, as well as, other applications in many industries.
Casing Pipe
Steel casing pipe is a type of pipe used in the construction of wells, particularly in the oil and gas industry. It is used to line the borehole that is being dug into the ground to get oil. Just like the drill pipe, the steel pipe casing can also withstand axial tension. This is a large-diameter pipe inserted into a drilled borehole and held into place with cement. The casing is subject to the axial tension of its dead weight, the external pressure of the rock surrounding it, and the internal pressure of the purging fluid.
The well-cemented pipe acts as the structural component of the well and offers hole integrity. It prevents the well from collapsing when the drilling process is on. Good quality, well cemented casing can stay in place for the whole life of the well.
Tubing:
Oil well tubing pipe is inserted inside the wellbore through the oil well casing pipe, which helps the transportation of the hydrocarbons to the surface. It is pipe 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 is subjected to high pressure during the extraction process, and needs to be thick, strong, and sturdy. Production tubing is available in various sizes ranging from ¾" to 4 ½".
The oil well tubing protects the oil well casing from wear and tear due to corrosive fluids, sand, paraffin etc. Tubing can be replaced in case of damage, which is not possible with oil well casing.
