Estimating and Optimizing the Amount of Generated Hydrocarbon by Determining Kinetic Parameters (A, E) in Pabdeh, Gurpi, and Kazhdumi Source Rocks With an Open Pyrolysis System

Abstract

One of the standard methods of estimating the amount of hydrocarbon generated is determining the kinetic parameters of source rock samples. Therefore, three immature samples from well-known Iranian source rocks (Pabdeh, Gurpi, and Kazhdumi) artificially were matured by an open pyrolysis system (Rock-Eval 6) at temperature rates of 5 and 15 ı C/min in bulk. Optimization was done by Optkin software. Kinetic parameters (A, E) and amount of generated hydrocarbon was determined. The results show different kinetic parameters for each sample and significant differences between them and the global kinetic parameters. Consequently, to get an accurate kinetic model in a petroleum system, a strategy for determining kinetic parameters on any new source rock samples is proposed.
