ABSTRACT:
A longitudinally compact mechanism for anchoring a well tool to a casing includes a plurality of first slip members and a plurality of second slip members. The first slip members and the second slip members are carried on the well tool at the approximate same longitudinal position, and the first slip members are alternately circumferentially positioned with the second slip members. Each slip member is expanded by relative movement of an independent piston operatively connected thereto.
