北海盆地南部的勘探历史可以追溯到1858年的德国，德国在大约一个世纪的时间里是欧洲石油工业的中心，1934年至1945年是石油发现的复苏时期。1963年，随着人们认识到荷兰格罗宁根天然气田的巨大规模，这种情况发生了戏剧性的变化。岩心资料显示，Rotliegend储层向西延伸至北海南部。在1965年12月至1966年10月期间，五个主要天然气发现的总储量接近20万亿立方英尺，足以使英国垄断市场饱和。到1969年，随着廉价的地震船和挪威海域10亿桶的油田的出现，英国的勘探活动转移到了北海中部和北部。直到1981年，英国南部北海一直处于停滞状态，由于天然气短缺，英国天然气公司通过提高新天然气的价格来鼓励新的活动，石炭纪很快成为勘探目标。与此同时，在荷兰陆地和海上以及德国陆地地区的勘探发现了稳定的天然气流，并从沉积岩中提取了一些石油，这些都是后来使用三维地震数据得到的。
Abstract Exploration history in the Southern North Sea Basin extends back to 1858 in Germany, which was the centre of Europe’s oil industry for about a century, with a resurgence in oil discoveries from 1934 to 1945. This changed dramatically in 1963 with the realization of the immense size of the Dutch Groningen gas field. Core data indicated that the Rotliegend reservoir extended westward into the southern North Sea. Between December 1965 and October 1966, five major gas discoveries totalled reserves of almost 20 tcf, sufficient to saturate the UK monopoly market. By 1969, with cheaper seismic ships and a billion barrel oil field in Norwegian waters, UK exploration activity shifted to the central and northern North Sea. The UK southern North Sea became a backwater until about 1981 when, with a pending shortage, British Gas encouraged renewed activity by increasing the price for new gas, the Carboniferous soon becoming an exploration target. Meanwhile, exploration in the Dutch land and offshore, and German land areas resulted in a steady stream of gas discoveries and some oil derived from Liassic source rocks, both enhanced by the later use of 3D seismic data.
