    Abstract: An underground plume of water and soil which has been contaminated typically by H2S and/or hydrocarbon leakage from underground fuel containers is mitigated by a process of injecting a combination of colloids, peroxides and enzymes. This is accomplished by obtaining core samples to determine the extent of contamination thereby defining the perimeter of the plume, and drilling a series of injection well sites on a pavement or other surface to mitigate the leakage. In a first stage of mitigation, a colloid containing micelles is pressured into the injection wells, the colloid functioning to neutralize hydrocarbons, MTBE, solvents, and similar compounds, thereby mitigating the plume contamination. In a second stage, if mitigation of the plume contamination proves insufficient using colloid treatment, peroxides are then pressured into the injection wells. Typical peroxides could include hydrogen peroxide and various other peroxides.

  • Publication number: 20080142224
    Abstract: A method to clean a wellbore and the near wellbore area adjacent to the wellbore of a hydrocarbon bearing formation adjacent to the production zone of the wellbore is provided. A method to clean a casing inserted into a wellbore is also disclosed. A method for cleaning a wellbore of fracturing fluid, with or without proppant is also disclosed. Each of the methods includes the steps of injecting either liquid carbon dioxide or a treatment medium comprising liquid carbon dioxide into a wellbore through tubing such that the location at which the treatment medium is administered may be controlled. In some embodiments, pressure within the wellbore is regulated in order to either maintain the treatment medium in the liquid state, or allow at least a portion of the treatment medium to vaporize upon introduction into the wellbore. Once the treatment medium has at least partially vaporized it will loosen and/or entrain undesirable materials from within the wellbore or casing.

  • Patent number: 7343969
    Abstract: A secondary packing arrangement is provided for use with a well having a reciprocating pump and polished rod, and in combination with a stuffing box, the stuffing box being modified. Packing seals, a barrier fluid and a pressure transmitter cooperate with modified stuffing box components to regulate the pressure on either side of a packing seal. The barrier fluid is contained above the packing seal, with well fluids and accompanying pressures being contained below the packing seal, such that if leakage occurs, relatively clean barrier fluids are leaked instead of well fluids. The pressure across the packing seal is substantially balanced across the packing seal, or the well fluid side pressure is less than the barrier fluid side, thus reducing the occurrence of leakage and extending the life of the packing seal. Sources for the well fluids cooperating with the pressure transmitter include the well's flow line and casing.

  • Patent number: 7021373
    Abstract: A system and method for pumping water from a wellbore to a surface location using an improved motorless water pump. The improved motorless water pump is a downhole hydraulic ram pump powered by the renewable energy source, groundwater. As water falls down a wellbore from an upper strata to a lower strata, the conversion of the water's momentum to energy is used to compress air captured in the ram's pressure chamber. The compressed air contained in the pressure chamber pushes down on the water captured in the pressure chamber causing the water to exit the pressure chamber through an outlet and into tubing. The water in the tubing is responsive to the pressure in the chamber rising to the surface.

  • Publication number: 20020174982
    Abstract: A method and system for producing a mixed gas-oil stream wherein at least a portion of the gas is separated downhole by an auger separator which is comprised of an upstream and a downstream section. As the mixed stream flows through a converging passageway in the upstream section and gas is separated by an auger, the velocity of the stream is increased thereby reducing the temperature and pressure of the stream. This allows more of the condensate to remain with the liquids and not be separated with the gas. The liquids exit the upstream section and are produced to the surface. The separated gas flows through a diverging passageway in the downstream section where a portion of the reduced pressure is regained before the gas either produced to the surface or compressed for downhole injection.
