Remote set tool with contingency trigger and system

Abstract

A remote set tool arrangement including a tool, a primary trigger operatively connected to the tool, and a contingency trigger operatively connected to the tool. A borehole system including a borehole in a subsurface formation, a string in the borehole, and the remote setting tool arrangement disposed within or as a part of the string.

1 . A remote set tool arrangement comprising:
 a tool having an atmospheric chamber;   a primary trigger operatively connected to the tool and configured to communicate a pressure source to the atmospheric chamber upon triggering; and   a contingency trigger operatively connected to the tool and configured to communicate the pressure source to the atmospheric chamber upon triggering.   
     
     
         2 . The arrangement as claimed in  claim 1  wherein the primary trigger is an e-trigger. 
     
     
         3 . The arrangement as claimed in  claim 1  wherein the contingency trigger comprises a redundant flow path and a valve. 
     
     
         4 . The arrangement as claimed in  claim 3  wherein the redundant flow path accesses an actuation flow path between and including a housing of the primary trigger and the tool. 
     
     
         5 . The arrangement as claimed in  claim 3  wherein the valve is a sliding sleeve. 
     
     
         6 . The arrangement as claimed in  claim 1  wherein the contingency trigger comprises a break-off plug. 
     
     
         7 . The arrangement as claimed in  claim 6  wherein the contingency trigger further comprises a sliding plug breaker. 
     
     
         8 . The arrangement as claimed in  claim 1  wherein the contingency trigger comprises a redundant flow path and a rupturable closure. 
     
     
         9 . The arrangement as claimed in  claim 8  wherein the closure is a thin wall portion covering the redundant flow path. 
     
     
         10 . The arrangement as claimed in  claim 8  wherein the closure is a burst disk. 
     
     
         11 . The arrangement as claimed in  claim 1  wherein the contingency trigger comprises a cyclic trigger. 
     
     
         12 . The arrangement as claimed in  claim 1  wherein the tool includes a plurality of control line feedthroughs. 
     
     
         13 . The arrangement as claimed in  claim 12  wherein the plurality of control line feedthroughs include one that begins at an end of the tool and terminates at an actuation pressure chamber of the tool. 
     
     
         14 . The arrangement as claimed in  claim 13  wherein the end is an uphole end. 
     
     
         15 . The arrangement as claimed in  claim 14  wherein an actuation pathway begins downhole of the tool, extends through a first of the plurality of control lines, reverses direction and extends through the one of the plurality of control lines. 
     
     
         16 . The arrangement as claimed in  claim 13  wherein a control line of the plurality of control lines extending through the one feedthrough is sealingly terminated at the actuation pressure chamber. 
     
     
         17 . A borehole system comprising:
 a borehole in a subsurface formation;   a string in the borehole; and   the remote setting tool arrangement as claimed in  claim 1  disposed within or as a part of the string.
