Abstract
A downhole activation assembly includes a housing that is operatively connectable to a downhole tool and that has a passage for flow of fluid therethrough. An indexing assembly is positionable in the housing, includes a multiple position indexer and an indexing tube, and is operatively connectable to the downhole tool. A sleeve valve includes a fixed sleeve portion and a movable sleeve portion that is positionable in the housing passage and defines a ball passage therethrough. A valve seat in the sleeve valve is configured to receive the ball such that the flow of the fluid is selectively restricted through the ball passage. The movable sleeve is engagable with the indexing tube to selectively shift the indexer between multiple positions whereby the downhole tool is selectively activatable.
