Embodiment Construction

[0016]FIG. 1 schematically depicts an exemplary operating environment for a consumable downhole tool 100. As depicted, a drilling rig 110 is positioned on the earth's surface 105 and extends over and around a well bore 120 that penetrates a subterranean formation F for the purpose of recovering hydrocarbons. At least the upper portion of the well bore 120 may be lined with casing 125 that is cemented 127 into position against the formation F in a conventional manner. The drilling rig 110 includes a derrick 112 with a rig floor 114 through which a work string 118, such as a cable, wireline, E-line, Z-line, jointed pipe, or coiled tubing, for example, extends downwardly from the drilling rig 110 into the well bore 120. The work string 118 suspends a representative consumable downhole tool 100, which may comprise a frac plug, a bridge plug, a packer, or another type of well bore zonal isolation device, for example, as it is being lowered to a predetermined depth within the well bore 12...

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is related to commonly owned U.S. patent application Ser. No. 11 / 423,079 entitled “Consumable Downhole Tools” and U.S. patent application Ser. No. 11 / 423,081 entitled “Methods for Removing Consumable Downhole Tools,” both filed on the Jun. 8, 2006 and incorporated by reference herein.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.REFERENCE TO A MICROFICHE APPENDIX[0003]Not applicable.FIELD OF THE INVENTION[0004]The present invention relates to consumable downhole tools and methods of removing such tools from well bores. More particularly, the present invention relates to downhole tools comprising materials that are burned and / or consumed when exposed to heat and / or an oxygen source and methods and systems for consuming such downhole tools in situ.BACKGROUND[0005]A wide variety of downhole tools may be used within a well bore in connection with producing hydrocarbons or reworking a well...
