ABSTRACT:
A method of assisting production of an oil and/or gas well involves reducing the pressure at the top of a well and aid in oil and gas production. If any gas exists in the produced fluid, gas expansion at the resulting reduced pressure will reduce the fluid density in the production pipe, thus further assisting fluid production. If some secondary production enhancement is in use (balance beam, downhole pump, gas lift, surfactant, etc.), this invention will increase the efficiency of the secondary lift. If supplemental gas is introduced anywhere along the production pipe as a “gas lift” method of secondary production, this supplemental gas expansion at the resulting reduced pressure will reduce the fluid density in the production pipe, thus further assisting fluid production. If the pressure reducer is applied to the line pipe carrying the production fluids remote from the wellhead, the reduced pressure will enhance fluid velocity and amount; expanding gas in the fluid at lower pressures in the pipe will increase the flowing velocity of the fluid.
