Dispensing and collection fluids with wireline chamber tool

Abstract

A wireline chamber tool for dispensing and collecting fluid is disclosed. The wireline chamber tool includes a tool body having an internal chamber therein, a piston within the internal chamber that divides the internal chamber into a proximal portion and a distal portion, a circulation port disposed in the tool body, where the circulation port is configured to provide fluid communication between the distal portion and an outside of the tool, and a filling port disposed in the tool body, wherein the filling port is configured to provide fluid communication between the outside of the tool and the proximal portion.

What is claimed is: 
     
         1 . A wireline chamber tool for dispensing and collecting fluid, the wireline chamber tool comprising:
 a tool body having an internal chamber therein;   a piston within the internal chamber, wherein the piston divides the internal chamber into a proximal portion and a distal portion;   a circulation port disposed in the tool body, wherein the circulation port is configured to provide fluid communication between the distal portion and an outside of the tool; and   a filling port disposed in the tool body, wherein the filling port is configured to provide fluid communication between the outside of the tool and the proximal portion.   
     
     
         2 . The wireline chamber tool of  claim 1 , wherein the piston is configured to move along a longitudinal axis of the internal chamber and push fluid out of the chamber. 
     
     
         3 . The wireline chamber tool of  claim 2 , wherein the piston is electrically actuated. 
     
     
         4 . The wireline chamber of  claim 2 , further comprising an electrically actuated pump configured to pull well fluid into the proximal portion through the filling port and pressurize stored fluid in the distal portion. 
     
     
         5 . The wireline chamber tool of  claim 1 , wherein the circulation port is disposed on a side wall of the tool body. 
     
     
         6 . The wireline chamber tool of  claim 1 , wherein a proximal end of the tool body comprises a threaded connection configured to mechanically couple with a sample tool. 
     
     
         7 . A method of operating a wireline chamber tool comprising:
 filling a distal portion of an internal chamber within the wireline chamber tool with a first fluid;   actuating a piston within the internal chamber to dispense the first fluid through a circulation port; and   filling a proximal portion of the internal chamber with a second fluid.   
     
     
         8 . The method of  claim 7 , further comprising performing a sampling operation substantially simultaneously with the actuating the piston. 
     
     
         9 . The method of  claim 7 , wherein the first fluid comprises one selected from a group consisting of acid and clean well fluid. 
     
     
         10 . The method of  claim 7 , wherein the second fluid comprises contaminated well fluid. 
     
     
         11 . The method of  claim 7 , further comprising detecting formation damage, wherein the actuating the piston is performed in response to detecting formation damage. 
     
     
         12 . The method of  claim 7 , further comprising detecting that a drill string comprising the wireline chamber tool is stuck within the well, wherein the actuating the piston is performed in response to detecting that the drill string is stuck. 
     
     
         13 . A method of operating a wireline chamber tool comprising:
 actuating a piston within an internal chamber of the wireline chamber tool to dispense a first fluid through a circulation port; and   performing a sampling operation substantially simultaneously with the actuating the piston.   
     
     
         14 . The method of  claim 13 , wherein the first fluid comprises one selected from a group consisting of acid and clean well fluid. 
     
     
         15 . A method of operating a wireline chamber tool comprising:
 actuating a piston within an internal chamber of the wireline chamber tool;   drawing contaminated well fluid into an internal chamber of the wireline chamber tool; and   performing a sampling operation substantially simultaneously with the actuating the piston.
