Surfaced mixed epoxy method for abandoning well

Abstract

A two part epoxy resin system is surface mixed in a method of plugging an abandoned well. This surface mixed epoxy resin is then placed in the well at the desired plugging depth. Finally, the mixture in situ forms a cementing plug.

1 . A method of treating an abandoned well having a well fluid residing in the well, the method comprising:
 (A) providing a epoxy resin component and an activator component;   (B) surface mixing the components to form an epoxy system, wherein the system has a density greater than the density of the well fluid; and   (C) placing the system in the abandoned well.   
   
   
       2 . The method of  claim 1 , wherein steps (C) and (D) are carried out utilizing one or more of a dump bailer; pumping through tubing, drillpipe, work strings or tubulars; gravity flow; and bull heading. 
   
   
       3 . The method of  claim 1 , wherein the well fluid density is in the range of about 8.33 ppg up to about 20.0 ppg, the activator density is in the range of about 8.33 ppg up to about 21.0 ppg, and the resin density is in the range of about 8.54 up to about 22.0 ppg. 
   
   
       4 . A method of plugging an abandoned well having a well fluid residing therein, the method comprising:
 (A) providing a epoxy resin component and an activator component;   (B) surface mixing the components to form an epoxy system, wherein the system has a density greater than the density of the well fluid;   (C) placing the system in the abandoned well; and   (D) allowing the mixture to form a cementing plug.   
   
   
       5 . The method of  claim 4 , wherein steps (C) and (D) are carried out utilizing one or more of a dump bailer; pumping through tubing, drillpipe, work strings or tubulars; gravity flow; and bull heading. 
   
   
       6 . The method of  claim 4 , wherein the well fluid density is in the range of about 8.33 ppg up to about 20.0 ppg, the activator density is in the range of about 8.33 ppg up to about 21.0 ppg, and the resin density is in the range of about 8.54 up to about 22.0 ppg. 
   
   
       7 . An abandoned well comprising:
 a well bore; and   an epoxy mixture residing in the well bore.
