Abstract:
The present disclosure relates to a method and apparatus for removing debris from a wellbore, comprising providing a surface pump for supplying a fluid stream, a work string fluidly connected to the surface pump for passing the fluid stream from the surface pump, a tool body fluidly connected to the work string, including a plurality of tool body exit ports for passing the fluid stream from the work string into an annular space of the wellbore, and a collection chamber fluidly connected to and downhole from the tool body, for accepting uphole flow of the fluid stream including entrained wellbore debris. The fluid stream including entrained wellbore debris is drawn upward through the collection chamber, and the fluid stream from the work string and the fluid stream from the collection chamber are passed into the annular space of the wellbore. In addition, a cartridge may be inserted into the tool body.

Claim (Index 15):
A method for removing debris from a wellbore, comprising:\n providing a work string, for passing a fluid stream from a top of the wellbore; a tool body fluidly connected to the work string, including a plurality of tool body exit ports for passing the fluid stream from the work string into an annular space of the wellbore; a collection chamber fluidly connected to and downhole from the tool body, for accepting uphole flow of the fluid stream including entrained wellbore debris; and a cartridge, insertable into the tool body, including a cartridge central fluid passageway and a plurality of cartridge Venturi nozzle tubes distributed around the lateral circumference of the cartridge, wherein each Venturi nozzle tube is fluidly connected to one of the plurality of tool body exit ports, the cartridge Venturi nozzle tubes for providing suction inside the cartridge, drawing the fluid stream up from the collection chamber, into the cartridge central fluid passageway, through the cartridge Venturi nozzle tubes and through the tool body exit ports into an annular space of the wellbore; drawing the fluid stream including entrained wellbore debris upward through the collection chamber; passing the fluid stream from the work string and the fluid stream from the collection chamber into the annular space of the wellbore.
