Maturity of carboniferous source rocks in Central Onshore Netherlands. the impact of the Permian thermal anomaly
conference paper
Pre-Westphalian layers are considered as potential source rocks in the Netherlands. However, there is little amount of information available on their maturity. 3D basin modelling is carried out on Central Onshore Netherlands to investigate the maturity of the deep Carboniferous source rocks. A detailed 3D geological model is used as input which is based on the results of the recent mapping activities in the Netherlands. Heat flow is modelled in the study area based on the tectonic evolution of the structures. The Permian uplift (Saalian event) and the associated magmatic activities are taken into account. This event has resulted in a thermal peak depicted as a peak in heat flow in the Permian. The thermal peak has influenced the maturity of the Carboniferous source rocks causing early maturity and hydrocarbon generation. Upper Carboniferous source rocks (Westphalian formations) seem to have produced some hydrocarbons in later stages which could be responsible for charging the gas fields.
