<p>A method is provided to remove contaminates that are more dense than water from a contaminated volume of earth, the contaminates pooled (107) above a layer of earth, the method comprising the steps of: providing an essentially horizontal wellbore (204) along the interference between the layer of earth and the contaminates; heating at least a portion of the contaminates in situ from the wellbore (204); and removing the heated contaminates by heating through the horizontal wellbore. The wellbores preferably include both heaters (103, 105) and provide a conduit for removal of contaminates, and preferably also provide heaters located within the wellbores in addition to those heaters required to vaporize the contaminates to maintain the contaminates in a vapour state until the vapours reach a well head and can be further processed at the surface.</p> |
