GORfit

Primary cracking of kerogen leads to the formation of petroleum and the kinetic parameters of source rocks are essential for assessing the distribution of hydrocarbons within a sedimentary basin. Secondary cracking of unexpelled oil is the major pathway for the generation of volatile shale oil to shale gas, and kinetic models have to be used as part of liquids/gas-in-place estimations.

The GORFit approach is a time-effective, straightforward method to determine these primary and secondary cracking kinetics for individual source rocks (or oil asphaltenes) for direct import into petroleum system modelling software.

The GORFit model utilizes both open-system and closed-system MSSV pyrolysis data to directly distinguish partly overlapping primary and secondary oil and gas evolution profiles on the basis of simple stoichiometric relationships.
