The Paleozoic sedimentary section of the Arabian plate recorded the effects of numerous fluctuations in sea level and gentle epeirogenic movements. Eustatic changes in sea level over the Arabian plate resulted in transgressions and regressions and created many local and regional unconformity surfaces, identified by missing section and nondeposition. The distant deformation of the Caledonian tectonic orogeny and mountain building of the North Atlantic region, and the later Hercynian tectonic event, are partially responsible for eustatic sea-level changes. Additionally, detailed evidence of Paleozoic glacial erosion and glacial eustasy in the regressive sedimentary section over uplifted paleohighs comes from deep wells penetrating local exotic tectonic blocks. The resulting surfaces mark the sea-level falls associated with the glacial events in the Ordovician, Late Devonian, and Carboniferous–early Permian sediments. The depositional settings of the Cambrian–upper Permian rocks include deltaic and glacial settings and are expressed as alluvial–fluvial fans that grade into braided plains and shallow-marine carbonates flanked by distal shales. Late Permian sediment fill accompanied the development of widespread accommodation, resulting from a major sea-level rise, coinciding with a major period of carbonate–evaporite deposition, in which clastic sediments were only a minor factor. The regional sedimentary facies have good reservoir quality and are juxtaposed to regional source rocks and seals associated with both structural and minor stratigraphic traps. Production occurs in Precambrian through Permian strata in which mature clastic and shallow-water carbonate reservoirs occur, commonly sealed by shales, and sourced by Silurian hot shales or older source rocks in the section.

横跨阿拉伯板块的古生代层序地层、沉积系统和油气生境

阿拉伯板块的古生代沉积剖面记录了海平面多次波动和温和的表生运动的影响。阿拉伯板块上海平面的海平面变化导致海侵和海退，并产生了许多局部和区域不整合面，这些不整合面由缺失剖面和非沉积物识别。北大西洋地区加里东期构造造山运动和山脉构造的遥远变形，以及后来的海西期构造事件，是造成海平面变化的部分原因。此外，在隆起的古隆起的海退沉积剖面中，古生代冰川侵蚀和冰川消退的详细证据来自于穿透当地外来构造块的深井。由此产生的表面标志着与奥陶纪、晚泥盆世和石炭纪-早二叠世沉积物中的冰川事件相关的海平面下降。寒武纪-上二叠纪岩石的沉积环境包括三角洲和冰川环境，表现为冲积-河流扇，分级为辫状平原和浅海碳酸盐岩，两侧是远端页岩。晚二叠世沉积物填充伴随着广泛的可容纳性的发展，这是由于海平面的主要上升，与碳酸盐 - 蒸发岩沉积的主要时期相吻合，其中碎屑沉积物只是次要因素。区域沉积相具有良好的储层质量，与区域烃源岩和与构造和次要地层圈闭相关的密封并列。
