Abstract:
A downhole tool slip mechanism including a cone, cage, and slip disposed on a mandrel. The cone and cage can be move in relation to one another, and the come may be locked into place during run-in and retrieval downhole. The cage contains slip slots contains a spring retaining finger for a spring that resides between the retention finger and the slip. This spring serves to bias the slip inward during run-in and retrieval. The slip slots have load-bearing shoulders used to engage the slip during retrieval. The slips outer surface is completely covered in wickers so that the slip can sustain greater loads when set in place. Additionally, the slip has load-bearing shoulders with an increased thickness cross-section to sustain greater loads during retrieval while minimizing slip and cage failures.
