Abstract
A method for utilizing gas produced from an in situ conversion process includes heating an organic-rich rock formation, for example an oil shale formation. The method may include producing a production fluid from the organic-rich rock formation where the production fluid has been at least partially generated as a result of pyrolysis of formation hydrocarbons located in the organic-rich rock formation. The method may include obtaining a gas stream from the production fluid, where the gas stream comprises combustible hydrocarbon fluids. The method may include separating the gas stream into a first composition gas stream and a second composition gas stream, where the composition of the first composition gas stream is a low BTU gas stream maintained in a substantially constant condition and passing the first composition gas stream through a gas turbine to form a gas turbine exhaust stream, where the gas turbine is connected to an electrical generator.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
