Kerogen (IMAGE) Rice University Caption Rice University research scientist Philip Singer holds kerogen, a component of oil shale, extracted and compressed for study into a pellet. Because natural gas escapes from kerogen at atmospheric pressure, the Rice lab reloads it with gas at pressures up to 5,000 psi and then probes it with a nuclear magnetic resonance spectrometer. The results are used to validate molecular simulations that may someday help characterize wells before their hydrocarbons are extracted.
