Abstract: A method of determining a thermal maturity model of a subterranean region of interest is disclosed. The method includes obtaining a plurality of rock samples for the subterranean region of interest. The method further includes determining a first porosity value, a second porosity value, and a volume fraction of organic matter, for each of the plurality of rock samples. The method further includes determining, for each of the plurality of rock samples, a thermal maturity index based, at least in part, on the first porosity value, the second porosity value and the volume fraction of organic matter. The method further includes determining the thermal maturity model based, at least in part, on the thermal maturity index for each of the plurality of rock samples.
