Abstract

A system includes a downhole valve, a pressure gauge mounted on the downhole valve, and a power source for powering the pressure gauge. The pressure gauge is programmed to interpret a pressure command characterized by at least two variables of a pressure signal to open the downhole valve.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A system, comprising:
 a downhole valve;   a pressure gauge mounted on the downhole valve; and   a power source for powering the pressure gauge,   wherein the pressure gauge is programmed to interpret a pressure command characterized by at least two variables of a pressure signal to open the downhole valve.   
     
     
         2 . The system of  claim 1 , wherein the pressure gauge is fixedly mounted on the downhole valve. 
     
     
         3 . The system of  claim 1 , wherein the pressure gauge is pivotably mounted on the downhole valve. 
     
     
         4 . The system of  claim 1 , wherein the power source is a battery on board the pressure gauge. 
     
     
         5 . The system of  claim 1 , wherein the at least two variables of the pressure signal comprise: amplitude and time. 
     
     
         6 . The system of  claim 1 , wherein the pressure gauge is a quartz gauge. 
     
     
         7 . The system of  claim 1 , wherein the pressure gauge communicates with a surface unit via telemetry. 
     
     
         8 . A method, comprising:
 sending a pressure command downhole to open a downhole valve, the pressure command characterized by at least two variables of a pressure signal;   interpreting the pressure command downhole using a pressure gauge mounted on the downhole valve; and   opening the downhole valve.   
     
     
         9 . The method of  claim 9 , wherein the pressure gauge is fixedly mounted on the downhole valve. 
     
     
         10 . The method of  claim 9 , wherein the pressure gauge is pivotably mounted on the downhole valve. 
     
     
         11 . The method of  claim 8 , wherein the pressure gauge is powered by a battery on board the pressure gauge. 
     
     
         12 . The method of  claim 8 , wherein the at least two variables of the pressure signal comprise: amplitude and time. 
     
     
         13 . The method of  claim 8 , wherein the pressure gauge is a quartz gauge. 
     
     
         14 . The method of  claim 8 , wherein the pressure gauge communicates with a surface unit via telemetry.
