Level of Protection

A level of protection is a barrier to fluid migration into fresh water aquifers that has mechanical integrity, and its integrity can be monitored with some degree of confidence. Well construction components, such as surface casing, production casing, tubing and packer, and wellbore plugs, are such barriers.
