A method of removing a downhole tool from a wellbore comprising contacting the tool with a heat source wherein the tool comprises at least one load-bearing component comprising a thermally degradable material. A method of reducing the structural integrity of a downhole tool comprising fabricating the load-bearing components of the tool from a thermally degradable material. A method of removing a downhole tool comprising mechanically milling and/or drilling the tool from a wellbore wherein the tool comprises at least one load bearing component comprising a phenolic resin wherein the phenolic resin comprises a rosole, a novalac or combinations thereof.

Consumable downhole tools

A downhole tool releasing mechanism which includes a collet for releasably engaging a mandrel of a downhole tool. A retaining band is circumferentially disposed about the fingers of the collet for maintaining engagement of the collet and the mandrel prior to application of a predetermined axially directed force on the releasing mechanism. Upon application of such a force the collet fingers expand, breaking the shear band, the mandrel is released and the downhole tool is disengaged.

Downhole tool releasing mechanism

A wellbore servicing system, comprising a plurality of sleeve systems disposed in a wellbore, each sleeve system comprising a seat and a dart configured to selectively seal against the seat to the exclusion of other seats, the seats each comprising an upper seat landing surface and the darts each comprising a dart landing surface, wherein the darts each comprise a dart landing surface that is configured to complement an upper seat landing surface of the seat to which the dart is configured to selectively seal against.

System and method for servicing a wellbore

A tool that is easily convertible from a frac plug to a bridge plug is disclosed. The tool comprises a mandrel with a mule shoe connected to the lower end thereof. A closing ball is disposed in a cavity defined by the mule shoe. The mandrel is threaded to receive a plug at or near the upper end thereof to convert the frac plug to a bridge plug.
