A wellsite pumping system, comprising a gas processing system including a source of compressed gas, the source of compressed gas having a low pressure inlet and a high pressure outlet, coil tubing connected to the high pressure outlet of the ga s processing system, the coil tubing including a first tubing string connected to the hig h pressure outlet and a second tubing string running parallel to the first tubing string and having an opening for entry of fluid at a remote end from the high pressure outlet; and a venturi connecting the second tubing string to the first tubing string such that, in operation, passage of gas through the venturi from the first tubing string draws production fluid into the second tubing string. Preferably, the second tubing string is suspended within the first tubing string. The venturi may be formed by a horizontal passageway communicating with a vertical passageway with a restriction.
