A method for preventing wax deposition in oil wells with packers is disclosed. The method includes feeding a motive fluid from a storage tank to an ejector having a converging section for inlet of the motive fluid, a diverging section for outlet of the motive fluid, and a constricted section with an opening in between the converging section and the diverging section; removing a water and water vapor from an annulus of the oil well using the ejector, wherein flowing of the motive fluid through the converging section and diverging section of the ejector creates a pressure loss and increases the velocity of the motive fluid, which creates suction in the constricted section to evacuate water and vapour from the annulus of the oil well, thereby remediating wax deposition in the oil well. |
