Th e Integrator-X Packer from Evolution Oil Tools, also known as an Arrow Set, or AS-1X Packer, is a mechanical set, double-grip, retrievable casing packer that effectively meets the requirements for zone isolation, injection and production. The full opening ID allows unrestricted flow and passage of full gage wireline tools and accessories. Mechanical lock-set action closes an internal bypass and allows application of pressure above or below the packer. The bypass closes during setting of the packer and opens to equalize pressure before releasing the slips.
