  • Patent number: 5101899
    Abstract: The production of petroleum from a petroleum bearing formation through an electrically conductive production tubing suspended in a wellbore extending into said formation and lined by an electrically conductive tubular casing is accomplished by a plurality of method steps. A power source of low frequency alternating current is provided. Then, an electrical circuit path is completed, including the production tubing and casing as current paths. The low frequency alternating current is modified by creating transients in it. The modified low frequency alternating current is electrically coupled to the electrical circuit. Mechanical vibration is electrically induced in the casing and production tubing to substantially, continuously, mechanically vibrate the petroleum bearing formation and enhance petroleum production.
