maturation process under thermodynamically controlled incongruent melting process of kerogen. However,
the thermodynamic concept is tending to make the concept of oil window irrelevant. Use of biomarker
parameters on prograding aromatization of rings in hopens and steranes may be better parameters for
maturation o over the epimerization and isomerization processes.
The thermodynamic concept also has greater bearing on changes in porosity and permeability of
combined inorganic and organic matrix and would demand more research in relation to source potential
and ease of primary migration and potential of retaining the generated products.
The need for greater integration of geochemistry, coal petrography, palynology, and petrophysics
continues to exist. With the source rocks being taken as tight shale gas reservoirs, the integration is being
taken forward to make first level evaluation of source rock potential through surface seismic surveys where
seismic attributes are calibrated from petropysical well logs which in turn are calibrated with the
geochemical attributes of source rocks.
Petroleum industry will continue to demand both geochemical coal petrographical and
palynological data for petroleum source rock potential evaluation for reducing risk in petroleum exploration
and for maximizing value creation by obtaining better focus for areas where high quality petroleum systems
may be present.
