After a well has been drilled, will it become a producer, or will it be plugged and abandoned as a dry hole? Completion operations must be carried out if the operator decides to proceed with the well development. You may need to employ the help of professionals for open-hole casing installation in the USA.
The steps necessary to turn a drilled well into a producing well are referred to as well completion. It requires casing, cementing, perforating, gravel packing, and planting a production tree are among the stages. You might also need an excellent place to find PVC pipe elevators in the USA.
Casing
Case the hole is the first stage in finishing a well. Should the drilling fluids be removed after a well has been drilled, the structure will gradually close in on itself.
The casing prevents this from happening while also shielding the good stream from contaminants such as dust or sand.
The casing is a hollow tube made up of steel pipes that are welded together to form a continuous tube. It is inserted into the well. The well's various levels determine the diameter of the casing that will be fitted. Production casing, surface-type casing, intermediate casing, and conductor casing make the distinct levels of a casing program.
There are also two styles of casing that can be used in a well. A solid strand of steel pipe makes up one sort of casing. If the formation is firm and will stay that way during the well's life, the solid casing is used.
If the well has loose sand that could penetrate the well stream, a wire screen liner is inserted in the casing to help prevent the sand from entering the wellbore.
Cementing
Cementing the well is the next phase in the excellent completion process. Pumping cement slurry into the well to replace current drilling fluids and fill the space between the casing and the drilled well's sides is part of this process.
The slurry, which is made up of a particular combination of additives and cement, is allowed to solidify, sealing the well against non-hydrocarbons that might try to enter the well stream and effectively putting the casing in place.

Open-Hole Casing
There are two types of well completion methods employed at the reservoir level: open-hole and cased-hole completions. A well dug to the top of the hydrocarbon reservoir is referred to as an open-hole completion. At this point, the well is cased and left open at the bottom.
Open-hole completions, also called top sets or barefoot completions can save money on the casing when the reservoir is solid and well-known. You can find an excellent open hole casing installation in the USA.
