The packer forms the basis of the cased-hole completion design. The packer is a sealing device that isolates and contains produced fluids and pressures within the wellbore to protect the casing and other formations above or below the producing zone. This is essential to the basic functioning of most wells. The casing sizes in which CPS provides the packers are from size 4-1/2" to 9-5/8" with tubing connection from size 2-3/8"- 3- 1/2".
