Applications
5-1/2 inch J55 casing is available for surface and intermediate casing strings, water and gas injection wells, geothermal wells and salt cavern storage. The grade is also used as conductor casing on shallow wells and as structural well liner where a moderate yield strength is sufficient. Coupling profiles match standard wellhead, hanger and make-up equipment, so the string can be run with conventional handling tools.
