Abstract: A technique facilitates application of increased force on a downhole tool, such as a shifting tool. According to an embodiment, a shifting tool is sized for deployment along the interior of a well string to enable shifting of a sliding sleeve. The shifting tool comprises a plurality of keys which are movably mounted for actuation between a contracted position and an extended position engaging the sliding sleeve. A plurality of pads may be actuated with the plurality of keys so as to form a flow restriction between the shifting tool and the surrounding well string. As a result, fluid pumped down between the shifting tool and the well string establishes a pressure differential across the flow restriction which helps move the shifting tool and the sliding sleeve to a desired position.

Abstract: A technique facilitates operation of a slip assembly, e.g. a frac plug assembly, having a plurality of slips. The plurality of slips may selectively be forced in a radially outward direction via, for example, a cone so as to set the slips against a surrounding casing or other tubing. The slip assembly further comprises a mechanism which allows different amounts of radial movement of individuals slips to ensure sufficient setting of the individual slips when the surrounding tubing is oval or otherwise out of round.
