Hydrocarbon generation modelling in the Permian and Triassic strata of the Polish Basin: implications for hydrocarbon potential assessment

“…Nu mer ical mod el ling tech niques en able the sim u la tion of the com plex set of in ter act ing phys i cal and chem i cal pro cesses tak ing place dur ing the evo lu tion of a sed i men tary ba sin. The quan ti fi ca tion of geo log i cal evo lu tion is based on a con cep tual model, which de scribes the geo log i cal evo lu tion of the study area (Waples et al, 1992;Hantschel and Kauerauf, 2009). The con cep tual model was con structed in a tem po ral frame work in which geochronologic en ti ties called 'events' form the ba sis of the tem po ral frame work and the in put data.…”
