Water Line Control For Sample Bottle Filling

Abstract

An arrangement for sampling a fluid, having a sample bottle with an associated piston, wherein the piston separates the sample bottle into an inlet side and a water side, a fluid sample line connected to the sample bottle at the inlet side, the fluid sample line transporting a fluid, a solenoid connected to the sample bottle on the water side of the sample bottle and a check valve connected to the sample bottle on the water side of sample bottle, wherein fluid enters the sample bottle on the inlet side upon actuation of at least one of the solenoid and the check valve on the water side of the sample bottle.

What is claimed is: 
     
         1 . An arrangement for sampling a fluid, compromising:
 a sample bottle with an associated piston, wherein the piston separates the sample bottle into an inlet side and a water side;   a fluid sample line connected to the sample bottle at the inlet side, the fluid sample line transporting a fluid;   a solenoid connected to the sample bottle on the water side of the sample bottle; and   a check valve connected to the sample bottle on the water side of sample bottle, wherein fluid enters the sample bottle on the inlet side upon actuation of at least one of the solenoid and the check valve on the water side of the sample bottle.   
     
     
         2 . An arrangement for sampling a fluid, compromising:
 a sample bottle with an associated piston wherein the piston separates the sample bottle into an inlet side and a water side;   a fluid sample line connected to the sample bottle at the inlet side, the fluid sample line transporting a fluid; and   a relief valve connected to the sample bottle connected to the water side of the sample bottle, such that actuation of the relief valve causes fluid to be accepted into the sample bottle with the associated piston.   
     
     
         3 . The arrangement according to  claim 2 , further comprising:
 a check valve connected to the water side of the sample bottle.   
     
     
         4 . The arrangement according to  claim 3 , further comprising:
 a solenoid connected to at least one of the relief valve and the check valve.   
     
     
         5 . The arrangement according to  claim 1 , wherein the fluid sample line is further configured with a seal valve. 
     
     
         6 . The arrangement according to  claim 2 , wherein the fluid sample line is further configured with a seal valve. 
     
     
         7 . A method for directing a fluid flow into a sample bottle; comprising:
 pumping the fluid flow with a pump through a fluid transfer line;   hydraulically locking a piston in the sample bottle, wherein a fluid below the piston is pressure equalized to a pressure of the wellbore;   accepting fluid from the fluid transfer line into the sample bottle through an inlet of the sample bottle, wherein a fluid pressure of the fluid in the fluid transfer line is at a pressure over that for actuation of a relief valve pressure thereby causing the fluid to enter the sample bottle; and   sealing the bottle after an amount of fluid has been accepted into the sample bottle.   
     
     
         8 . The method according to  claim 7 , wherein the amount of fluid accepted into the sample bottle is an entire volume of the sample bottle. 
     
     
         9 . The method according to  claim 7 , wherein the sealing of the bottle is automatically performed after a preset amount of fluid is accepted. 
     
     
         10 . The method according to  claim 7 , further comprising:
 deploying the sample bottle downhole prior to pumping the fluid flow through the fluid transfer line.   
     
     
         11 . The method according to  claim 10 , further comprising:
 retrieving the sample bottle from downhole.   
     
     
         12 . The method according to  claim 10 , wherein the sample bottle is a detachable component of a downhole tool.
