some cases can charge into a reservoir rock.

Kerogen takes on additional importance in unconventional resources, particularly shale. In these formations, oil and gas are produced directly from the kerogen-rich source rock (i.e. the source rock is also the reservoir rock). Much of the porosity in these shales is found to be hosted within the kerogen, rather than between the mineral grains that occur in conventional reservoir rocks. Thus, kerogen controls much of the storage and transport
