| description | A downhole tool held in a wellbore with a unidirectional slip and a bidirectional slip. The bi-directional slip has a slip frame and at least two slip banks. The slip frame comprises a center ring and a plurality of slats extending longitudinally uphole and downhole from the center ring and spaced radially about the center ring so as to define at least two pairs of slots. Each pair of slots has a first slot extending longitudinally uphole from the center ring and a second slot extending longitudinally downhole from the center ring. The slip banks have a first gripping bank, a second gripping bank and a groove between the first gripping bank and second gripping bank. The first gripping bank and second gripping bank each have an outer surface configured to grip the casing. The first gripping bank is slideably received in the first slot and the second gripping bank is slideably received in the second slot such that the slip bank has a set position in which the groove receives a portion of the center ring and the first gripping bank and second gripping bank extend radially outward from the slip frame so as to be able to engage the casing, and the slip bank has an unset position in which the slip bank is positioned radially inward from the set position. |
