Abstract
A constructed permeability control infrastructure can include a permeability control impoundment defining a substantially encapsulated volume. A comminuted water-containing hydrocarbonaceous material can form a permeable body within the encapsulated volume. The impoundment includes a water vapor outlet for removing water vapor from the encapsulated volume. A heating device is also embedded within the permeable body to provide convective heating thereof. The permeable body can be heated sufficient to initially remove water therefrom as a water vapor. The water vapor can be removed from the infrastructure via the outlet which can be controlled or shut off when the permeable body is sufficiently dewatered. The dewatered permeable body can then be heated sufficient to remove hydrocarbons therefrom. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.
