Multi-spheric interactions driven differential formation and accumulation of hydrocarbon resources in the North Sea Basin
The North Sea Basin is the most important oil and gas producing area in Europe and the birthplace of many classic petroleum geological theories.From the perspective of multi-spheric interactions in the Earth,this study investigated the rift-foreland-rift evolution process of the North Sea Basin,which was controlled by the deep dynamic driving forces of the continental collision orogeny,mantle plume uplift,and intraplate deformation.The North Sea Basin was found to have drifted northward since the Carboniferous and passed through the low-latitude Hadley and the mid-latitude Ferrel cells.Two sets of main hydrocarbon source rocks have formed,the coals and coal measures of the Upper Carboniferous Westphalian and the marine shale of the Upper Jurassic Kimmeridge Clay Formation.We propose that the deep processes,tectonic activity,and trans-gression-climate evolution jointly controlled the types and horizons of the source rocks,reservoirs,and seals in different regions of the North Sea Basin.In the southern North Sea Basin,a Carboniferous-Lower Triassic gas-rich petroleum system was formed,which is characterized by transitional coal measure source rocks,desert aeolian sandstone reservoirs,and evaporite cap rocks.In the northern North Sea Basin,an Upper Triassic-Paleogene oil-rich petroleum system was formed,which is characterized by marine graben-type source rocks,deltaic sandstone and marine limestone reservoirs,and marine tight marl and shale cap rocks.The late tectonic burial and uplift in the North Sea Basin further controlled the processes of oil and gas generation and accumulation,ultimately leading to a differential distribution pattern which is oil rich in the northern part and gas rich in the southern part of the basin.In the future,there is an urgent need to re-examine the mechanisms for the petroleum generation and accumulation in large mature exploration areas(e.g.,super basins such as the North Sea)and low exploration areas(e.g.,the Okhotsk Sea and Arctic regions)from the perspective of multi-spheric interactions in the Earth in order to provide new theoretical support for increasing the identification of oil and gas reserves globally.The development of artificial intelligence in the petroleum industry should focus on the massive amount of exploration and geological data collected in the North Sea Basin.Through digital geological innovation,carbon neutral comprehensive utilization of oil,gas,and associated resources(e.g.,helium and hydrogen)can be achieved,providing a new paradigm for global oil and gas exploration and development.
