We have obtained artificial maturated samples trough exposing extracted kerogen to temperatures ranging from 380 to 420 °C and obtained kerogen with 13C-NMR structural parameters (%aromaticity, average chain length and average aromatic cluster size) equivalents to Vaca Muerta organic matter from wells coming from different production stages of maturity (from late oil to dry gas). A molcular model compatible with NMR results have been made.
