    摘要: A method is provided to remove contaminants from near-surface contaminated soil, the method including the steps of: placing a plurality of metal sheets on the surface above the contaminated soil to form a contiguous cover over at least a portion of the contaminated soil; seal welding adjacent metal sheets together; cutting a plurality of holes in the metal sheet; providing a plurality of heater wells and a plurality of vapor extraction wells into the contaminated soil through the holes cut in the metal sheets; providing vapor extraction wellheads over the vapor extraction wells, the vapor extraction wellheads sealed to the metal sheets; and removing contaminants from the near-surface soil by heating from the heater wells and extracting vapor through the vapor extraction wells. The wells are preferably both heater wells and vapor extraction wells, and the wellheads are preferably bolted to a flange which is welded to the metal sheets to ensure a positive seal at the surface. Insulation is preferably placed over the metal sheets prior to heating of the soil, and a rain cover placed over the insulation to keep rain out of the insulation and away from the soil being heated. The edges of the contiguous cover are preferably sealed by a vertical metal sheet placed into the soil, with a 90 degree angled lip on top, and the lip attached to the edge of the continuous sheet to form the seal.

    摘要: A method is provided to remove contaminants that are more dense than water from a contaminated volume of earth, the contaminants pooled above a layer of earth, the method comprising the steps of: providing an essentially horizontal wellbore along the interface between the layer of earth and the contaminants; heating at least a portion of the contaminants in situ from the wellbore; and removing the heated contaminants by heating through the horizontal wellbore. The wellbores preferably include both heaters and provide a conduit for removal of contaminants, and preferably also provide heaters located within the wellbores in addition to those heaters required to vaporize the contaminants to maintain the contaminants in a vapor state until the vapors reach a well head and can be further processed at the surface.

    摘要: A system for treating a subsurface formation includes a wellbore at least partially located in a hydrocarbon containing formation. The wellbore includes a substantially vertical portion and at least two substantially horizontal or inclined portions coupled to the vertical portion. A first conductor is at least partially positioned in a first of the two substantially horizontal or inclined portions of the wellbore. At least the first conductor includes electrically conductive material. A power supply electrically excites the electrically conductive materials of the first conductor such that current flows between the electrically conductive materials in the first conductor, through at least a portion of the formation, to a second conductor at least partially positioned in a second of the two substantially horizontal or inclined portions of the wellbore. The current resistively heats at least a portion of the formation between the two substantially horizontally oriented or inclined portions of the wellbore.
