Figure F11. ACORK plumbing schematic. During installation, circulation from the drill ship is routed to the mud motor at the bottom of the casing string. Use of a "go-devil" allows this circulation to be diverted (dashed line) to fill the packers, then to shift the spool valves from their initial deployment position (dashed line) to their monitoring position (solid line).
