Introduction:
Engineers transport hydrocarbons from the reservoir to the surface using wells as a conduit. Hydrocarbons are highly combustible, thus special measures must be taken to guarantee that they are brought to the surface in a safe, regulated manner. This transportation mostly takes place in locations that are very rarely seen with the physical eyes.
Tubing and casing play a crucial role in the well’s construction. Casings protect the well’s integrity and, in some cases, like tubing, give fluids a means to flow through the well. Engineers must carefully construct casings and tubing to prevent failure and accidents due to fluid pressure and well trajectory.
The type of material, as well as its length, weight, and thickness, are all taken into account throughout the design process. Understanding the options and matching each well with the proper casing and tubing design are crucial since different wells in various terrains that are aimed at various reservoirs must be taken into account separately.
