An improved well service tool, having an elongated, central hollow mandrel with threaded connections on either end, first and second axially spaced circumferential recesses formed in the exterior surface of the mandrel;
- split rings, removably mounted around the mandrel in the recesses;
- a stabilizer element mounted on the exterior of each split ring;
- and a cylindrical service element, removably disposed around the central mandrel between the stabilizer elements, and
- wherein the improvement comprises a third circumferential recess in the exterior surface of the mandrel, the third recess positioned axially between the first and second recess, a third split ring, removably mounted around the mandrel in the recess;
- a third stabilizer element mounted on the exterior of the third split ring and an additional service element, removably disposed around the central mandrel and positioned between the adjacent stabilizers.
A method of servicing a wellbore at a subterranean location, comprising the steps of:
- providing a well servicing tool, configured to comprise an elongated, central hollow mandrel with threaded connections on either end, a intermediate circumferential recesses formed in the exterior surface of the mandrel between two axially spaced circumferential recesses formed in the exterior surface of the mandrel;
- split, rings, removably mounted around the mandrel in the recesses;
- stabilizer elements, removably mounted on the exterior of each split ring;
- and cylindrical-shaped first and second service elements, removably mounted on the central mandrel between the adjacent stabilizer elements, wherein the method comprises:
- moving the well servicing tool into and out of the wellbore to service the wellbore;
- thereafter reconfiguring the servicing tool, the reconfiguration comprising removing from the mandrel the stabilizer element mounted on the split ring at the intermediate recess and removing from the mandrel the first and second service elements;
- without reinstalling the stabilizer at the intermediate recess, removably installing a third cylindrical service element on the central mandrel positioned between the two remaining stabilizer elements;
- and
- moving the reconfigured well servicing tool into and out of the wellbore to service the wellbore.
