Appl. No.:

12/028621

Inventors:

Todd Dana - Park City UT, US
James W. Patten - Sandy UT, US

Assignee:

Red Leaf Resources, Inc. - Sandy UT

International Classification:

C10G 1/04

US Classification:

208106, 208187, 299 2, 405132, 405133, 4051501, 4051502

Abstract:

A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a stationary permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom within a temperature range which is sufficient to substantially avoid formation of carbon dioxide or non-hydrocarbon leachates. 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.

Abstract:

A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume having substantially permeable side walls and a substantially impermeable cap. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom without contamination or substantial leaching of materials outside of the impoundment. 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.

Abstract:

A method of transporting heavy hydrocarbons can include blending a kerogen oil with a bitumen to form a blended oil sufficient to render the blended oil transportable through an extended pipeline. The blended oil can be substantially free of additional diluents or viscosity modifiers and can be readily pumped through the extended pipeline from a source location to a destination location.

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.

Abstract:

A constructed permeability control infrastructure can include a permeability control impoundment, which defines a substantially encapsulated volume. The infrastructure can also include a comminuted hydrocarbonaceous material within the encapsulated volume. The comminuted hydrocarbonaceous material can form a permeable body of hydrocarbonaceous material. The infrastructure can further include at least one convection driving conduit oriented in a lower portion of the permeable body to generate bulk convective flow patterns throughout the permeable body. An associated method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure, which defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. A heated fluid can be passed throughout the permeable body in bulk convective flow patterns to remove hydrocarbons from the permeable body.

Abstract:

A method of sequestering carbon dioxide emissions during recovery of hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. During heating, the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Additionally, during heating, any carbon dioxide that is produced can be sequestered. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.

A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. During heating and removal of hydrocarbons and subsequent thereto a positive pressure can be maintained within the encapsulated volume by means of a non-oxidizing gas to expedite flushing of hydrocarbonaceous material, inhibit unwanted entry of oxygen into the encapsulated volume and remove recoverable hydrocarbons following the heating process.

Abstract:

A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A mined hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. Hydrocarbon products can be collected from intermediate locations within the permeable body. Advantageously, an intermediate fluid collection system can be used to draw a hydrocarbon product from the permeable body at preselected locations. Such intermediate collection can provide hydrocarbon product fractions which can reduce or eliminate the need for full-scale distillation of a hydrocarbon product having a full range of products such as that typically found in crude oil. In addition, product quality can be tailored by monitoring such intermediate draws and adjusting operating parameters accordingly.
