ABSTRACT:
A linear indexing apparatus and associated methods of using same provide convenient operation of tools in a subterranean wellbore. In a preferred embodiment, a linear indexing apparatus has an outer tubular housing and a tubular mandrel axially slidably disposed within the housing. Two sets of slips are utilized to incrementally displace the mandrel relative to the housing. A piston associated with one of the sets of slips permits the mandrel to be incrementally indexed in response to a series of repeated applications of a predetermined differential pressure.
