WELLBORE GRAVEL PACKING APPARATUS AND METHOD

摘要

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.
