The Geological Results of the Search for Oilfield in Great Britain

Summary The search for oil in Great Britain has been carried out in five separate geological provinces—in the Mesozoic of southern England, the Carboniferous of the eastern Midlands, the Triassic and Carboniferous of Lancashire, the Permian of North Yorkshire and the Calcirferous Sandstones Series of the Midland Midland Valley of Scotland. Four oilfields have been discovered in Nottinghamshire and a small field in Lacashire. In addition, a large amount of new stratigraphical information has beeb provided by the exploration borings and extensive geophysical surveys have added cosiderably to existing knowledge of the structure of the Carboniferous in the eastern Midlands. The boring records have given much new information on the development of coal seams in the areas east and sout-east of the present Nottinghamshire Coalfield. A boring in North Yorkshire proved the presence of potash salts in the Permian indicating conditions comparable with those of North-West Germany.
