Abstract
A downhole assembly for deliquifying a wellbore. In an embodiment, the assembly comprises a nozzle section including a converging nozzle and a diverging nozzle in fluid communication with the converging nozzle. In addition, the assembly comprises a throat section including a convergent throat passage proximal the diverging nozzle and a cylindrical throat passage distal the diverging nozzle and extending axially from the convergent throat passage. The convergent throat passage and the cylindrical throat passage are in fluid communication with the diverging nozzle. Further, the assembly comprises a diffuser section coaxially aligned with the throat section. The diffuser section includes a divergent diffuser passage extending axially from the straight throat passage.
