Float collar equipment can be bonded to an inside of a casing string via an adhesive. An annulus can be located around an outside of a float collar housing and the inside of the casing string where the adhesive can be injected. The float collar housing does not require external threads or packers to secure the housing to the inside of the casing string. An injection sub can be used to inject the adhesive into the annulus. After curing or drying, the adhesive bonds the housing to the casing string. A seat, seat housing, or float shoe nose can be attached to the float collar housing via an adhesive or threads. The float collar housing can house one or more float assemblies. The float collar equipment can be bonded to the casing string at a wellsite or remote location prior to use in a cementing operation.

A downhole retrieval tool for engaging and retrieving an object from a wellbore includes a mandrel and a grapple having a contracted position and an expanded position. In the expanded position, the grapple engages the object for retrieval. The grapple is operably associated with an expansion member disposed on the mandrel to facilitate movement of the grapple between the contracted and expanded positions. The expansion member is releasably connected to the mandrel. In the event that the downhole tool and object, once secured to each other, are unable to be retrieved from the wellbore, the expansion member can be released from the mandrel which, in turn, causes the grapple to release from the object so that the downhole tool can be removed from the wellbore. A stored energy member facilitates movement of the grapple from the contracted position to the expanded position.
