Bypass tool for use with a tubing anchor

Abstract

A bypass tool including a bypass tubing insertable through a tubing anchor. The bypass tool also includes a lower bypass nipple supported by a lower end of the tubing anchor and to permit gas to pass from outside of a bottom hole assembly (BHA) to between the bypass tubing and the tubing anchor and an upper bypass nipple supported by an upper end of the tubing anchor to permit the gas to pass from between the bypass tubing and the tubing anchor to back outside of the BHA. A method of recovering production fluids from a well using the bypass tool. The method includes positioning a bypass tool at a desired location in a well. The method also includes pumping a gas through the bypass tool.

What is claimed is: 
     
         1 . A bypass tool, the bypass tool comprising: 
 a bypass tubing insertable through a tubing anchor;   a lower bypass nipple supported by a lower end of the tubing anchor and to permit gas to pass from outside of a bottom hole assembly (BHA) to between the bypass tubing and the tubing anchor; and   an upper bypass nipple supported by an upper end of the tubing anchor to permit the gas to pass from between the bypass tubing and the tubing anchor to back outside of the BHA.   
     
     
         2 . The bypass tool of  claim 1  wherein the bypass tubing is in fluid communication with a downhole tool disposed below the bypass tool in the BHA and an uphole tool disposed above the bypass tool in the BHA. 
     
     
         3 . The bypass tool of  claim 1  wherein the lower bypass nipple has a passageway disposed therein to permit at least a portion of the bypass tubing to extend therethrough. 
     
     
         4 . The bypass tool of  claim 1  wherein the upper bypass nipple has a passageway disposed therein to permit at least a portion of the bypass tubing to extend therethrough. 
     
     
         5 . The bypass tool of  claim 1  wherein the lower bypass nipple has a radial directed opening therein to permit the gas to pass from outside the BHA to between the bypass tubing and the tubing anchor. 
     
     
         6 . The bypass tool of  claim 5  wherein the upper bypass nipple has a radial directed opening therein to permit the gas to pass from between the bypass tubing and the tubing anchor to back outside of the BHA. 
     
     
         7 . The bypass tool of  claim 1  further comprising a lower tubing connector to connect a downhole tool disposed below the bypass tool in the BHA to the lower bypass nipple or to connect the tubing anchor to the lower bypass nipple. 
     
     
         8 . The bypass tool of  claim 1  further comprising an upper tubing connector to connect an uphole tool disposed above the bypass tool in the BHA to the upper bypass nipple or to connect the tubing anchor to the upper bypass nipple. 
     
     
         9 . The bypass tool of  claim 6  wherein the lower bypass nipple and the upper bypass nipple has multiple radial directed opening disposed therein. 
     
     
         10 . A method of recovering gas from an oil and gas well, the method comprising: 
 positioning a bypass tool at a desired location in a well;    and pumping a gas through the bypass tool.   
     
     
         11 . The method of  claim 10  wherein the bypass tool comprises: 
 a bypass tubing insertable through a tubing anchor; 
 a lower bypass nipple supported by a lower end of the tubing anchor and to permit gas to pass from outside of a bottom hole assembly (BHA) to between the bypass tubing and the tubing anchor; and 
 an upper bypass nipple supported by an upper end of the tubing anchor to permit the gas to pass from between the bypass tubing and the tubing anchor to back outside of the BHA. 
 
     
     
         12 . The method of  claim 11  wherein the bypass tubing is in fluid communication with a downhole tool disposed below the bypass tool in the BHA and an uphole tool disposed above the bypass tool in the BHA. 
     
     
         13 . The method of  claim 11  wherein the lower bypass nipple has a passageway disposed therein to permit at least a portion of the bypass tubing to extend therethrough. 
     
     
         14 . The method of  claim 11  wherein the upper bypass nipple has a passageway disposed therein to permit at least a portion of the bypass tubing to extend therethrough. 
     
     
         15 . The method of  claim 11  wherein the lower bypass nipple has a radial directed opening therein to permit the gas to pass from outside the BHA to between the bypass tubing and the tubing anchor. 
     
     
         16 . The method of  claim 15  wherein the upper bypass nipple has a radial directed opening therein to permit the gas to pass from between the bypass tubing and the tubing anchor to back outside of the BHA. 
     
     
         17 . The method of  claim 16  wherein the lower bypass nipple and the upper bypass nipple has multiple radial directed opening disposed therein. 
     
     
         18 . The method of  claim 11  wherein the bypass tubing extends entirely through the lower bypass nipple and the upper bypass nipple. 
     
     
         19 . The method of  claim 11  further comprising running flexible equipment through at least part of the bypass tool to extend the flexible equipment to a part of the well disposed downhole from the tubing anchor. 
     
     
         20 . The method of  claim 19  wherein the flexible tubing is capillary tubing used to deliver treatment fluids downhole from the tubing anchor.
