Abstract:
A method for treating a tar sands formation (32) in situ includes providing heat from one or more heat sources (30) to a portion of the tar sands formation. The heat may be allowed to transfer from the heat source(s) to a selected section of the formation to pyrolyze at least some hydrocarbons within the selected section. A mixture of hydrocarbons of a selected quality may be produced from the selected section by controlling production of the mixture to adjust the time that at least some hydrocarbons are exposed to pyrolysis temperatures in the formation.
Abstract:
A method is disclosed for treating a hydrocarbon containing formation in situ and producing a hydrocarbon fluid from the formation, wherein hydrocarbons present in the formation are pyrolysed at an elevated pressure with the application of a pressure/temperature control such that the pressure is at least the pressure which can be calculated for a selected temperature, or the temperature is at most the temperature which can be calculated for a selected pressure from the equation (I) wherein P is pressure (bar absolute), T is temperature ( DEG C), and A and B are predetermined parameters which relate to a property which is relevant to the quantity, the composition or the quality of the hydrocarbon fluids produced. Optionally the method is followed by the step of producing synthesis gas in-situ which step comprises reacting the hydrocarbon containing formation that has been treated with the method according to the invention with a synthesis gas generating fluid. Optionally converted hydrocarbons are produced by converting the synthesis gas so produced into hydrocarbons and/or energy is generated by expanding and/or combusting the synthesis gas so produced or using the synthesis gas so produced in a fuel cell.
Abstract:
The present invention provides a method for the production of synthesis gas from a hydrocarbon-containing subterranean formation comprising: providing heat to at least a portion of the subterranean formation such that at least a part of the heated portion reaches the pyrolysis temperature of kerogen, yielding pyrolysis products; collecting pyrolysis products from the subterranean formation; injecting a synthesis gas-generating component into the heated part of the formation, resulting in the production of synthesis gas by reaction of the synthesis gas-generating component with carbonaceous material remaining in the formation; and recovering synthesis gas. The synthesis gas thus produced can be used for Fischer-Tropsch synthesis, manufacture of ammonia, urea, methanol, methane and other hydrocarbons, or used as energy source, e.g. in fuel cells. Carbon dioxide produced in such use of the synthesis gas can be sequestered in the formation.

Optionally, the method is followed by the step of in-situ producing synthesis gas, which step comprises providing a partly depleted hydrocarbon containing formation which is treated according to the said method for treating a hydrocarbon containing formation in-situ, and reacting the hydrocarbon containing formation with a synthesis gas generating fluid. Optionally the synthesis gas so produced is converted into hydrocarbons; and/or energy is generated by expanding and/or combusting the synthesis gas so produced or using the synthesis gas so produced in a fuel cell.
Abstract:
Disclosed is a new process and apparatus for steam reforming of any vaporizable hydrocarbon to produce H2 and CO2, with minimal CO, and no CO in the H2 stream, using a membrane steam reforming (MSR) reactor and flame-less distributed combustion (FDC) which provides great improvements in heat exchange efficiency and load following capabilities to drive the steam reforming reaction. The invention also pertains to a zero emission hybrid power system wherein the produced hydrogen is used to power a high-pressure internally manifolded molten carbonate fuel cell. In addition, the design of the FDC-MSR powered fuel cell makes it possible to capture good concentrations of CO2 for sequestration or use in other processes.
