The present invention relates to an enhancer system of flow pattern applied mainly in gas-producing oil wells with liquid load problems, comprising mechanical elements that atomize the liquids accumulated at the bottom of the well facilitating their transport to surface, which is caused by the decrease of frictional pressure drops and weigh of the hydrostatic column. 1. It increases the recovery factor of well hydrocarbons, due to the reduction in the pressure requirement needed to administer the energy of the deposit; 2. It increases the lifting velocity of the produced fluids to a relatively high flow velocity of gas of 4-6 m/s; the gas expansion flows along with the condensed hydrocarbons and water, generating an uniform atomized mixture with lower density, which reduces the pressure gradient flowing in the production piping; 3. It increases the gas production, as the well production is continuous with a steady behavior even during the liquid discharge, it has a remarkable improvement in the flow pattern in the production piping by generating a homogenous dispersion of both phases; 4. It decreases the pressure drops along the production piping, as it is not allowed that the liquid accumulates at the bottom of the well; 5. It preserves the deposit energy due to the increase of the bottom pressure flowing; 6. It maintains the liquid production with a steady behavior caused by a improvement in the flow pattern of fluids along the production piping; and 7. It extends the flowing life of the wells as it preserves the energy in the deposit by reducing the pressure drops along the production piping.
