Venturi jet basket assembly for use in a wellbore and methods for use

Abstract

A venturi jet basket assembly adapted to be coupled to a tubing that extends into a wellbore includes a body and a jet nozzle subassembly. The body includes a wall that defines a passageway that extends longitudinally through the body. The body also includes an opening extending through the wall and into the passageway. The wall also includes a flute formed in an outer surface of the wall of the body. The flute is in fluid communication with the opening. The jet nozzle subassembly is disposed within the passageway and includes a jet nozzle. The jet nozzle is arranged to direct fluid received through the tubing through the opening and into the flute such that the fluid is guided into the wellbore by the flute.

         5 . The venturi jet basket assembly as recited in  claim 1 , wherein the flute varies in depth along its length such that the flute is deeper at a first end that is adjacent to the opening than at an opposite second end. 
     
     
         6 . The venturi jet basket assembly as recited in  claim 1 , further comprising a second body and a stem, the stem coupled at a first end to the jet nozzle subassembly and at a second end to the second body, wherein the stem retains the jet nozzle subassembly in position. 
     
     
         7 . The venturi jet basket assembly as recited in  claim 6 , wherein the stem includes an elongated shaft extending between a first end and a second end, the first end configured to couple to the jet nozzle subassembly and the second end configured to couple to the body. 
     
     
         8 . The venturi jet basket assembly as recited in  claim 1 , wherein at least a portion of the flute has a semi-circular cross section. 
     
     
         9 . The venturi jet basket assembly as recited in  claim 1 , wherein at least a portion of the flute has vertical side walls. 
     
     
         10 . A venturi jet basket assembly adapted to be coupled to a tubing that extends into a wellbore, the venturi jet basket comprising:
 a body including:
 a wall that defines a passageway that extends longitudinally through the body; 
 an opening extending through the wall and into the passageway; and 
 a flute formed in an outer surface of the wall of the body and in fluid communication with the opening, the flute extending helically about the body, the flute varying in depth along its length such that the flute is deeper at a first end that is adjacent to the opening than at an opposite second end; and 
   a jet nozzle subassembly disposed within the passageway and comprising a jet nozzle arranged to direct fluid received through the tubing through the opening and into the flute, wherein the fluid is guided into the wellbore by the flute.   
     
     
         11 . The venturi jet basket assembly as recited in  claim 10 , wherein the flute extends more than 90° around the body. 
     
     
         12 . The venturi jet basket assembly as recited in  claim 10 , comprising a plurality of flutes formed in the outer surface of the body, each of the plurality of flutes in fluid communication with one of a plurality of openings that extends through the wall and into the passageway, and wherein the jet nozzle subassembly includes a plurality of jet nozzles, each of the plurality of jet nozzles arranged to direct fluid through one of the plurality of openings and into one of the plurality of flutes. 
     
     
         13 . The venturi jet basket assembly as recited in  claim 10 , further comprising a second body and a stem, the stem coupled at a first end to the jet nozzle subassembly and at a second end to the second body, wherein the stem retains the jet nozzle subassembly in position. 
     
     
         14 . The venturi jet basket assembly as recited in  claim 13 , wherein the stem includes an elongated shaft extending between a first end and a second end, the first end configured to couple to the jet nozzle subassembly and the second end configured to couple to the body. 
     
     
         15 . The venturi jet basket assembly as recited in  claim 10 , wherein at least a portion of the flute has a semi-circular cross section. 
     
     
         16 . The venturi jet basket assembly as recited in  claim 10 , wherein at least a portion of the flute has vertical side walls. 
     
     
         17 . A method of collecting debris in a wellbore, comprising:
 deploying a venturi jet basket assembly in a wellbore, the venturi jet basket assembly comprising:
