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.
Casing is used for lining the complete borehole which has been dug into the ground to procure oil. Similar to the drill pipe, the oil well casing pipe is also subjected to axial tension, therefore they are required to be made from high-quality strong steel material. Casing is large diameter pipe which is held in place in the borehole using cement.
The diameters of casing pipe range from 4.5″ to 36″. 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.
The oil well casing pipe is further divided into:
Sizes:
Out Diameter: 1.315"- 20"
Wall Thickness: 0.133"-0.500"
Length:R1(group1),R2(group2),R3(group3)
