Oil generation and destruction models
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 using modelling software. 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. Because no source rock or oil is chemically identical, causing large differences in thermal response, default kinetic parameres implemented in standard modelling software packages lead to erroneous results.
We developed one of the most time-effective, straightforward methods to determine primary and secondary cracking kinetics for individual source rocks (or asphaltenes). 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.
Full geochemical screening is offered in order to select key areas and key samples for regional or prospect scale evaluations.
We provide kinetic parameters for primary oil, primary gas, and secondary gas generation from kerogen or oil that are ready for direct import into Petromod®.
