  • Patent number: 4458634
    Abstract: A control system for maintaining a desired water level range from electrodes spaced thereabove in a layer of oil where alternating current discharge occurs from electrode down to and through water to another electrode, with the electrical discharge occurring between electrodes disposed at all times in the hydrocarbon oil layer. With the situs of reaction being confined to the oil and the interstitial boundry between the oil and water, dangerous conditions of hydrogen generation are generally obviated over most state-of-the-art methods of producing hydrogen with a highly efficient production process. Hydrocarbon gases and vapors are also produced from the oil with a cracking process occuring to some extent incumbant with the A C discharge from the electrodes through the oil to the water. This has also been found to gradually upgrade the quality of the oil remaining while some is at the same time consumed in the system.

  • Patent number: 4444255
    Abstract: A pair of electrodes is floated on the surface of the oil at the base of a oil well. An AC high frequency current is imposed across the gap in the electrodes to develop microfine carbon which serves as a catalyst for the electrolytic decomposition of petroleum by a plurality of elongated, nonspark-generating field electrodes which develop a high energy field at the base of the well, such elongated electrodes also being immersed in the oil at the base of the well. The developed gases, consisting primarily of hydrogen, serve to both repressurize the well and diffuse within the oil bearing strata to laterally displace sufficient oil to adjoining wells for recovery at such adjacent sites. The combination of repressurizing and by means of low molecular weight gases, effects by diffusion, this lateral displacement of petroleum in recoverable amounts to adjacent pumping sites.

  • Patent number: 4233132
    Abstract: Electrodes are immersed within oil which forms a layer over a quantity of water. When current is passed between the electrodes which are held to a predetermined gap from the interstitial surface between the oil and water, water is caused to undergo electrodecomposition. Gaseous hydrogen is then recovered in the sealed space above the oil-water layers and the oxygen is caused to react with constituents in the oil layer.Consequently, there is produced continuously a quantity of hydrogen which is separately collected and is usable in gaseous form.
