Chemical analysis is evaluating promising rock units in generating oil and gas, so do you minimize the role of this aspect or there is any alternative method
Article Determination and applications of chemical analysis to evalu...
Hydrocarbons potentiality are deduced when several conditions are satisfied. Starting form source rock reaching oil window, then reservoir rock and a trap structure for conventional exploitation or enough thick and overpressure source rock for gas shale and oil shale explorations. Hence, geochemistry, geophysics, filed Geology and structural geology all are involved for potential evaluation.
Basin modeling based on the burial thermal history ,and determination of lithology for each formation overburied the source rocks and vitrinite reflectance ,and other agents could enable to setup model to indicate transformation ratio that declare the time and extent of oil generation and increasing of tempreature accordingly .
