Abstract
A downhole tool suitable for use in a wellbore that includes a wedge mandrel having a distal end; a proximate end; an outer surface; and a flowbore extending through the wedge mandrel from the proximate end to the distal end. The tool includes a fingered member disposed around the wedge mandrel. The tool includes a ball seat insert made of a reactive metal-based material, the ball seat insert disposed in the flowbore and engaged with a first set of threads. The tool includes a support platform disposed in the flowbore and engaged with a second set of threads.

A downhole tool suitable for use in a wellbore, the tool comprising:
- a wedge mandrel made of a composite filament wound material, the wedge mandrel further comprising:
- a distal end;
- a proximate end;
- an outer surface;
- and an inner flowbore extending through the wedge mandrel from the proximate end to the distal end, wherein the inner flowbore comprises a first set of threads at the distal end and a second set of threads at the proximate end;
- a fingered member disposed around the wedge mandrel;
- a seal element disposed around the wedge mandrel;
- an insert positioned between the fingered member and the seal element, and in proximity with an end of the fingered member;
- a ball seat insert made of a reactive metal-based material, the ball seat insert disposed in the inner flowbore and engaged with the first set of threads;
- a support platform disposed in the inner flowbore and engaged with the second set of threads;
- and
- a lower sleeve disposed around and engaged with the outer surface of wedge mandrel at the distal end,
- wherein the wedge mandrel further comprises a plurality of lateral windows configured for a plurality of respective support platform dogs to movingly engage therein, and wherein the fingered member also comprises a plurality of recessed regions configured for the plurality of respective support platform dogs to engage therein.

- actuating a setting device coupled with the downhole tool in order to set the downhole tool into at least partial engagement with a surrounding tubular;
- disconnecting the downhole tool from the setting device coupled therewith when the tensile load is sufficient to separation therefrom;
- seating a ball in a ball seat of the ball seat insert;
- and
- waiting an amount of time for the reactive material to react in a sufficient manner whereby a fluid may be produced through the flowbore.
