Abstract:
A technique facilitates deploying and setting a liner hanger assembly while securely retaining liner hanger slips during running-in-hole. The liner hanger assembly may comprise a variety of components such as a mandrel, a cone, a plurality of slips, a retention ring, and an actuator. The slips may each be configured with an upper retention end and a lower retention end having a plurality of angles which interlock with corresponding angles of the cone and the retention ring. Additionally, a portion of the actuator may be sized to slide over an axial end of the retention ring to prevent inadvertent decoupling of the slips after installing the slips along the exterior of the cone.
