Groningen Gas Field is located within the southern part of the South Permian Basin in the northeast Netherlands. Since several wells have been producing from the Carboniferous-Permian Petroleum System, the field is considered as mature for hydrocarbon exploration. More detailed work is necessary to evaluate further exploration and development opportunities. Thus, evaluation of the subsurface has been carried out as part of the petroleum system concept by using the basin modeling. In this study, seismic interpretation was performed by using 3-dimensional seismic and borehole data with Petrel software in order to understand stratigraphy and structural settings of the area. PetroMod basin analysis software has been used for 1-dimensional and 2-dimensional basin modeling study by integrating interpreted geophysical, geological and geochemical data. Results show that the most recognized traps were formed during pre-Zechstein, and the major generation-migration and accumulation of hydrocarbon commenced during Middle Jurassic and continues to the present time. Since the timing of main hydrocarbon generation varies spatially and has begun after trap formation, both early and late migration enhances the potential of the porous Upper Rotliegend reservoirs. Prospective hydrocarbon traps may occur in the southwestern regions of the basin due to shallower depth of burial. On the other hand, all local structural highs that formed as a result of salt movement create potential traps in the region.
