Abstract
A method for producing hydrocarbon fluids from an organic-rich rock formation to a surface facility is provided. The method may include heating the formation in situ to cause pyrolysis of formation hydrocarbons, and producing production fluids from the formation via two or more wells. The produced fluids have been at least partially generated as a result of pyrolysis of the formation hydrocarbons. In addition, the produced fluids comprise non-condensable fluids, or gases, which taken together have an averaged Wobbe Index which varies at a rate of more than 5% over a period of time. The method also includes controlling production from one or more of the wells such that a combination of the production fluids from the wells results in a combined gas stream that's averaged Wobbe Index varies at a rate of less than 5% over the period of time. The combined stream comprises combustible hydrocarbon fluids.
