Outline of presentation

Why organic shale?

NMR response of fluids in organic shale isolates

Why the large T1/T2 ratio for hydrocarbon in kerogen?

Bitumen also has large T1/T2 ratio

Some believe it due to paramagnetic materials

We hypothesize it due to proton dipole-dipole interactions

Test hypothesis using polymeric viscosity standards

Surface relaxivity of light hydrogen in kerogen or polymer
