A wellbore apparatus and method for use in a wellbore for completion and production are disclosed. The apparatus comprises an outer permeable material ( 15 ) in the wellbore comprising a first basepipe section ( 11 ) with at least a portion of the basepipe is perforated ( 21 ), the first basepipe is inside the outer permeable material ( 15 ) and at least part of the perforated basepipe is designed to be adjacent to a production interval ( 14 ), a second basepipe section ( 10 ) with at least a portion of the second basepipe is slotted ( 16 ), the second basepipe is inside the outer permeable material ( 15 ) and above the perforated basepipe section ( 11 ) designed to be adjacent to the production interval wherein at least a portion of the slotted basepipe is designed to be adjacent to a non production section of the wellbore. The production completion apparatus may be installed into the wellbore to provide redundancy against well-screen failure.
