US Classification:
166245, 1662721, 1662727, 166302, 166303
Abstract:
A method for treating a relatively permeable formation containing heavy hydrocarbons in situ may include providing heat from one or more heat sources to a portion of the formation. The heat may be allowed to transfer from the heat sources to a selected section of the formation. The transferred heat may pyrolyze at least some hydrocarbons within the selected section. A temperature proximate a selected portion of a heater well may be selectively limited to inhibit coke formation at or near the selected portion. A mixture of at least some hydrocarbons may be produced through the selected portion of the heater well.
Vacuum Method For Removing Soil Contaminants Utilizing Thermal Conduction Heating
US Patent:

Filed:
Dec 14, 1990

International Classification:
E02D 311
US Classification:
405128
Abstract:
An in situ method for removal of contaminants from soil imposes a vacuum on the soil through perforated heater wells that are positioned in the soil. The heater wells heat the soil to elevated temperatures by thermal conduction. The heater wells are permeable to vapors which emanate from the soil when heated and which are drawn toward the heater wells by the imposed vacuum. An impermeable flexible sheeting on the soil surface reduces the amount of air that is being pulled into the heater well from the atmosphere. A thermal insulator covers the soil surface and reduces heat losses from the soil surface. The heater wells are connected to a vacuum manifold for collection of vapors. A heat front moves away from the heater wells through the soil by thermal conduction, and the superposition of heat from a plurality of heater wells results in a more uniform temperature rise throughout the well pattern. Soil contaminants are removed by vaporization, in situ thermal decomposition, oxidation, combustion, and by steam distillation. Both the presence of water vapor and the low pressure results in vaporization of the contaminants at temperatures well below their normal boiling points.

An average temperature and/or pressure within the formation may be controlled to inhibit production of hydrocarbons that have carbon numbers greater than a selected carbon number. In some embodiments, the selected carbon number may be 25. A small amount of hydrocarbons having carbon numbers greater than the selected carbon number may be entrained in vapor produced from the formation.
