Hydraulic lock compensating dummy valve

Abstract

A dummy valve comprising a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber and associated systems and methods.

1 . A dummy valve comprising:
 a housing and   a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.   
     
     
         2 . The dummy valve of  claim 1 , wherein the housing and the rupture disc define a second internal chamber. 
     
     
         3 . The dummy valve of  claim 1 , wherein the rupture disc comprises a rupture material. 
     
     
         4 . The dummy valve of  claim 1 , wherein the rupture disc is a non-fragmenting disc. 
     
     
         5 . The dummy valve of  claim 1 , wherein the housing comprises an upper packer and a lower packer. 
     
     
         6 . The dummy valve of  claim 1 , wherein the housing comprises a screen portion. 
     
     
         7 . The dummy valve of  claim 1 , wherein the housing comprises a latch thread section. 
     
     
         8 . A gas lift system comprising:
 a gas lift mandrel comprising a first pocket and a second pocket;   a gas lift valve disposed within the first pocket; and   a dummy valve disposed within the second pocket, wherein the dummy valve comprises a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.   
     
     
         9 . (canceled) 
     
     
         10 . The gas lift system of  claim 8 , wherein the gas lift mandrel further comprises an intermediate section. 
     
     
         11 . The gas lift system of  claim 8 , wherein the first pocket comprises a first opening, a second opening, and one or more injection ports. 
     
     
         12 . The gas lift system  claim 8 , wherein the gas lift valve is a retrievable gas lift valve. 
     
     
         13 . The gas lift system of  claim 8 , wherein the second pocket comprises a first opening and a second opening. 
     
     
         14 . A method comprising:
 providing a gas lift mandrel, wherein the gas lift mandrel comprises a first pocket and a second pocket and   placing a dummy valve within the second pocket, wherein the dummy valve comprises a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.   
     
     
         15 . (canceled) 
     
     
         16 . The method of  claim 14 , wherein the gas lift mandrel comprises a gas lift valve disposed within the first pocket. 
     
     
         17 . The method of  claim 14 , further comprising running the gas lift mandrel into a subterranean formation. 
     
     
         18 . The method of  claim 14 , further comprising allowing the rupture disc to rupture. 
     
     
         19 . The method of  claim 18 , further comprising allowing fluid from the intermediate section to flow into the first internal chamber of the dummy valve. 
     
     
         20 . The method of  claim 18 , wherein rupture disc ruptures while a gas lift valve is placed within the first pocket of the gas lift mandrel.
