Abstract

A downhole device comprising: a body section, wherein the body section defines a cavity and has an inner diameter and an outer diameter and a nozzle section at a first end of the body section, wherein the nozzle section defines a cavity and has an inner diameter and an outer diameter.

What is claimed is: 
     
         1 . A downhole device comprising:
 a body section, wherein the body section defines a cavity and has an inner diameter and an outer diameter and   a nozzle section at a first end of the body section, wherein the nozzle section defines a cavity and has an inner diameter and an outer diameter.   
     
     
         2 . The downhole device of  claim 1 , wherein the inner diameter of the body section is from 0.3 inches to 2 inches and the outer diameter of the body section is from 2 inches to 5 inches. 
     
     
         3 . The downhole device of  claim 1 , wherein the body section has a length of from 5 feet to 50 feet. 
     
     
         4 . The downhole device of  claim 1 , wherein the inner diameter of the nozzle section tapers from a diameter equal to the inner diameter of the body section to a diameter equal to the outer diameter of the body section. 
     
     
         5 . The downhole device of  claim 1 , wherein the inner diameter of the nozzle section tapers from a diameter equal to the inner diameter of the body section to a diameter less than the outer diameter of the body section. 
     
     
         6 . The downhole device of  claim 1 , wherein the inner diameter of the nozzle section tapers from a diameter equal to the inner diameter of the body section to a diameter that is from 25% to 200% greater than the inner diameter of the body section. 
     
     
         7 . The downhole device of  claim 1 , wherein the nozzle section has a length of from 1 foot to 5 feet. 
     
     
         8 . The downhole device of  claim 1 , further comprising a second nozzle section at a second end of the body section. 
     
     
         9 . The downhole device of  claim 1 , further comprising a mixer disposed within the cavity define by the body section. 
     
     
         10 . The downhole device of  claim 1 , further comprising one or more movable balls disposed on an outside surface of the body section. 
     
     
         11 . A well bore system, comprising:
 a well bore;   a casing string disposed within the well bore;   and a downhole device disposed within the casing string, wherein the downhole device comprises: a body section and a nozzle section at a first end of the body section.   
     
     
         12 . The well bores system of  claim 11 , wherein the downhole device comprises a body section, wherein the body section defines a cavity and has an inner diameter and an outer diameter and a nozzle section at a first end of the body section, wherein the nozzle section defines a cavity and has an inner diameter and an outer diameter. 
     
     
         13 . The well bore system of  claim 11 , wherein the well bore is a vertical well bore or a horizontal well bore. 
     
     
         14 . The well bore system of  claim 11 , further comprising a second downhole device disposed within the casing string. 
     
     
         15 . The well bore system of  14 , wherein the first downhole device is disposed within the casing string 
     
     
         16 . The well bore system of  claim 11 , wherein the downhole device is disposed within the casing string near the bottom of the casing string. 
     
     
         17 . A method comprising:
 providing a well bore comprising a casing string disposed within the well bore;   installing a downhole device within the casing string, wherein the downhole device comprises a body section and a nozzle section at a first end of the body section; and   producing gas from the well bore.   
     
     
         18 . The method of  claim 17 , wherein the downhole device comprises a body section, wherein the body section defines a cavity and has an inner diameter and an outer diameter and a nozzle section at a first end of the body section, wherein the nozzle section defines a cavity and has an inner diameter and an outer diameter. 
     
     
         19 . The method of  claim 17 , wherein the downhole device is installed within the casing string before producing gas from the well bore. 
     
     
         20 . The method of  claim 17 , wherein the downhole device is installed within the casing string after producing gas from the well bore.
