Abstract
A method is for increasing the production of a hydrocarbon wellbore at its medium and last stage of exploitation, based on removal of the accumulated liquid phase from the bottom of the well. The method includes the installation of a device within the well. The device includes a mandrel and sealing assembly, with the nozzle installed inside the mandrel and above the sealing assembly. Apertures are drilled through the mandrel and the nozzle throat. The device creates the low pressure zone in the tubing of the well and evacuates the liquid phase from the tubing wall and the bottomhole to the gas-liquid upwardly directed flow core.
