API 5L Gr. B A106 A53 Seamless Precision Carbon Oil Casing Steel Pipe/Tube Product Description     API 5CT K55 J55 L80 N80 Premium Connection Casing For Oil Pipe How Does Casing Work? Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect and support the wellstream. In addition to providing stabilization and keeping the sides of the well from caving in on themselves, casing protects the wellstream from outside contaminants, as well as any fresh water reservoirs from the oil or gas that is being produced. Also known as setting pipe, casing a well involves running steel pipe down the inside of a recently drilled well. The small space between the casing and the untreated sides of the well is filled with cement to permanently set the casing in place.
