东格陵兰中部上二叠统生油层相对较厚，分布广泛，富含石油。它直接与构成主要潜在储集层的大型碳酸盐岩堆积物相邻。它立即被厚的粗粒砂岩覆盖，这些砂岩也是一个潜在的储集层。整个层序被上二叠统和下三叠统页岩覆盖，这些页岩可能起到海豹的作用。这对拉特以北的挪威大陆架有影响。北纬62°，有充分的理由相信该地区存在与东格陵兰岛相同类型的上二叠统岩石，它们埋藏得很深。上侏罗统的页岩在挪威陆架的大片区域是未成熟的，因此埋藏更深的上二叠统源岩的存在大大增加了该地区的石油潜力。完_第629页
The Upper Permian of central East Greenland contains a relatively thick, widely distributed, oil-prone source rock. It occurs directly adjacent to large, carbonate buildups that constitute the main potential reservoirs. It is immediately overlain by thick, coarse-grained sandstones that are also a potential reservoir. The whole sequence is draped by Upper Permian and Lower Triassic shales that may act as a seal. This has implications for the Norwegian shelf north of lat. 62°N. There are good reasons to believe that Upper Permian rocks of the same types as in East Greenland exist, deeply buried in this region. The Upper Jurassic shales are immature over large areas of the Norwegian shelf, and the presence of deeper buried Upper Permian source rock thus adds considerably to the petroleum potential of the area.
