Definition of Production Casing - IADC Lexicon

Production Casing. Casing that is the innermost string of casing in the well. Production fluids enter the casing below the production packer and continue to the surface through the production string. At a minimum, the production casing will be rated for the maximum anticipated pressure that may be encountered from the production zone.

What is Production Casing? - Definition from Petropedia

Production Casing refers to the casing that is run across the reservoir in sections through which the well will be drilling. It is one of the final intervals of the casing which is performed during the casing of a well. The Production Casing is the deepest section of casing in a well just above the hydrocarbon formations.
