Method of Blending Hazardous Chemicals to a Well Bore

Abstract

A method for blending a well treatment fluid at a well site, including (1) providing centrifugal pumps for pumping components of the well treatment fluid into a pipe, (2) providing valves for controlling the flow of the components of the well treatment fluid into the pipe, and (3) controlling the pumps and the valves so as to control the ratio of the components of the well treatment fluid being delivered to the pipe.

1 . A method for blending a well treatment fluid at a well site, comprising:
 providing a first centrifugal pump for pumping a first component of the well treatment fluid into a pipe;   providing a first valve for controlling the flow of the first component of the well treatment fluid into the pipe;   providing a second centrifugal pump for pumping a second component of the well treatment fluid into the pipe;   providing a second valve for controlling the flow of the second component of the well treatment fluid into the pipe; and   controlling the pumps and the valves so as to control the ratio of the first component of the well treatment fluid to the second component of the well treatment fluid being delivered to the pipe.   
   
   
       2 . The method of  claim 1 , further comprising:
 providing a third centrifugal pump for pumping a third component of the well treatment fluid into the pipe; and   providing a third valve for controlling the flow of the third component of the well treatment fluid into the pipe;   wherein controlling the pumps and the valves further controls the ratio of the third component of the well treatment fluid to the other components of the well treatment fluid being delivered to the pipe.   
   
   
       3 . The method of  claim 2 , further comprising:
 providing at least one liquid additive storage tank;   providing at least one liquid additive pump; and   providing at least one liquid additive valve for controlling the flow of liquid additive into the pipe;   wherein controlling the liquid additive pump and the liquid additive valve controls the ratio of the liquid additive to the other components of the well treatment fluid being delivered to the pipe.   
   
   
       4 . The method of  claim 3 , further comprising
 pumping the well treatment fluid from the pipe into the well.   
   
   
       5 . The method of  claim 2 ,
 wherein the well treatment fluid is an acidizing fluid; and   wherein the first component of the well treatment fluid is water.   
   
   
       6 . The method of  claim 5 ,
 wherein the second component of the well treatment fluid is a hazardous chemical.   
   
   
       7 . The method of  claim 6 ,
 wherein the hazardous chemical is Ammonium Bi-Fluoride.   
   
   
       8 . The method of  claim 7 ,
 wherein the third component of the well treatment fluid is hydrochloric acid.   
   
   
       9 . The method of  claim 2 ,
 wherein the well treatment fluid is a fracturing fluid.   
   
   
       10 . The method of  claim 2 ,
 wherein the well treatment fluid is a drilling mud.   
   
   
       11 . A system for blending a well treatment fluid at a well site, comprising:
 a first centrifugal pump for pumping a first component of the well treatment fluid into a pipe;   a first valve for controlling the flow of the first component of the well treatment fluid into the pipe;   a second centrifugal pump for pumping a second component of the well treatment fluid into the pipe;   a second valve for controlling the flow of the second component of the well treatment fluid into the pipe; and   means for controlling the pumps and the valves so as to control the ratio of the first component of the well treatment fluid to the second component of the well treatment fluid being delivered to the pipe.   
   
   
       12 . The system of  claim 11 , further comprising:
 a third centrifugal pump for pumping a third component of the well treatment fluid into the pipe; and   a third valve for controlling the flow of the third component of the well treatment fluid into the pipe;   wherein the means for controlling the pumps and the valves further controls the ratio of the third component of the well treatment fluid to the other components of the well treatment fluid being delivered to the pipe.   
   
   
       13 . The system of  claim 12 , further comprising:
 at least one liquid additive storage tank;   at least one liquid additive pump; and   at least one liquid additive valve for controlling the flow of liquid additive into the pipe;   means for controlling the liquid additive pump and the liquid additive valve so as to control the ratio of the liquid additive to the other components of the well treatment fluid being delivered to the pipe.   
   
   
       14 . The system of  claim 13 , further comprising
 means for pumping the well treatment fluid from the pipe into the well.   
   
   
       15 . The system of  claim 12 ,
 wherein the well treatment fluid is an acidizing fluid; and   wherein the first component of the well treatment fluid is water.   
   
   
       16 . The system of  claim 13 ,
 wherein the second component of the well treatment fluid is a hazardous chemical.   
   
   
       17 . The system of  claim 16 ,
 wherein the hazardous chemical is Ammonium Bi-Fluoride.   
   
   
       18 . The system of  claim 17 ,
 wherein the third component of the well treatment fluid is hydrochloric acid.   
   
   
       19 . The system of  claim 12 ,
 wherein the well treatment fluid is a fracturing fluid.   
   
   
       20 . The system of  claim 12 ,
 wherein the well treatment fluid is a drilling mud.
