What is a casing bowl?
A casing bowl is a type of work over tool. Many times when opening up older wells the liner may be damaged or, even in newer wells, may have been perforated during the course of running tools. The liner is cut off below the damaged section and the old liner is removed. The casing bowl is run in on the bottom of the new liner. If the old liner is lying off to the side an entry guide allows the operator to rotate to the right and drive the casing bowl over the liner stub. The casing bowl goes over the stub by 1 ½ to 2 feet. An inner grip ring with case hardened teeth bites into the stub. The liner is put in tension causing the grip ring further bite into the liner. A casing bowl can also have seals if required.
