Abstract
Downhole tools that have a housing and an actuation mechanism. The actuation mechanism is adapted to index in response to one or more balls being deployed into said tool and thereafter to actuate in response to another said ball being deployed into said tool. The indexing balls and the actuation ball are substantially identical. The actuation mechanism may comprise a member adapted for indexing from an initial position sequentially through one or more intermediate positions to a terminal position where the indexed member is mounted in an annular space between an outer wall and an inner wall. The tool may comprise a central conduit which is substantially uniform internal diameter substantially free of profiles. Methods are provided that include deploying an ancillary tool through the tool which has not been actuated or drilled out.
