One way to do it is to do lots of FOC tests & select the most 'organic'
samples for biological methane potential testing, or pyrolitic carbon /
pyrolysis. Both approaches can give you a theoretic gas yield over an
assumed timescale, given a known average bulk density, thickness of gassing
deposits etc.
Hope this is of some use,
