Dissolvable downhole plug

Abstract

Herein disclosed is a downhole tool comprising a dissolvable part, wherein the part is dissolved in the presence of moisture or water, at a temperature in the range of 150° F. to 400° F. and at a pressure in the range of 2 ksi to 12 ksi. In some embodiments, no solvent other than water is needed for the dissolvable part to dissolve. The dissolvable part is made from a material comprising resin or fiber or both. In some embodiments, at least 20% of the dissolvable part is dissolved. Also disclosed herein is a method for performing a downhole operation comprising: placing a downhole tool within a well bore, wherein the downhole tool comprises a dissolvable part, wherein the part is dissolved in the presence of moisture or water, at a temperature in the range of 150° F. to 400° F. and at a pressure in the range of 2 ksi to 12 ksi.

What is claimed is: 
     
         1 . A downhole tool comprising a dissolvable part, wherein said part is dissolved in the presence of moisture or water, at a temperature in the range of 150° F. to 400° F. and at a pressure in the range of 2 ksi to 12 ksi. 
     
     
         2 . The downhole tool of  claim 1  wherein no solvent other than water is needed for the dissolvable part to dissolve. 
     
     
         3 . The downhole tool of  claim 1  wherein the dissolvable part is made from a material comprising resin or fiber or both. 
     
     
         4 . The downhole tool of  claim 3  wherein the resin or fiber or both are dissolvable. 
     
     
         5 . The downhole tool of  claim 1  comprising a frac plug, a bridge plug, or a packer. 
     
     
         6 . The downhole tool of  claim 5  wherein the dissolvable part of the plug or packer is a wedge or cone. 
     
     
         7 . The downhole tool of  claim 5  wherein the plug or packer falls to the bottom of a wellbore after the dissolvable part of the plug or packer is dissolved for a period of time. 
     
     
         8 . The downhole tool of  claim 5  wherein the plug or packer is pushed to the bottom of a wellbore after the dissolvable part of the plug or packer is dissolved for a period of time. 
     
     
         9 . The downhole tool of  claim 1  wherein at least 20% of the dissolvable part is dissolved. 
     
     
         10 . A method for performing a downhole operation comprising:
 placing a downhole tool within a well bore, wherein the downhole tool comprises a dissolvable part,   wherein said part is dissolved in the presence of moisture or water, at a temperature in the range of 150° F. to 400° F. and at a pressure in the range of 2 ksi to 12 ksi.   
     
     
         11 . The method of  claim 10  comprising dissolving the tool for a period of time. 
     
     
         12 . The method of  claim 11  wherein dissolving the tool for a period of time takes place before performing the downhole operation or during performing the downhole operation or after performing the downhole operation. 
     
     
         13 . The method of  claim 10  wherein at least 20% of the dissolvable part is dissolved. 
     
     
         14 . The method of  claim 10 , wherein no solvent other than water is needed for the dissolvable part to dissolve. 
     
     
         15 . The method of  claim 10 , wherein the dissolvable part is made from a material comprising resin or fiber or both. 
     
     
         16 . The method of  claim 15 , wherein the resin or fiber or both are dissolvable. 
     
     
         17 . The method of  claim 10 , wherein the downhole tool comprises a frac plug, a bridge plug, or a packer. 
     
     
         18 . The method of  claim 17  wherein the dissolvable part of the plug or packer is a wedge or cone. 
     
     
         19 . The method of  claim 17  wherein the plug or packer falls to the bottom of a wellbore after the dissolvable part of the plug or packer is dissolved for a period of time. 
     
     
         20 . The method of  claim 17  comprising pushing the plug or packer to the bottom of a wellbore after the dissolvable part of the plug or packer is dissolved for a period of time.
