Short summary
In this article we report a multiscale approach for explaining why the transport of fluids in oil shales is so hindered. Thanks to nuclear and electronic magnetic resonances, we first demonstrate that the kerogen within the shale is capable of swelling in the presence of oil; and second we show that this swelling is reversible and reveals the presence of vanadyl porphyrin by breaking magnetic interaction. The magnetic interactions evidenced helps understand the very low mobility of hydrocarbons.
