Over 700 wells have been drilled in the Baltic Sea and about 40 significant accumulations of crude oil and natural gas have been discovered.[1] This is an incomplete listing of some of these offshore fields.

A particular feature of the Baltic Sea that affects the development of offshore oil and gas facilities are the large number of munitions and chemical weapons in some areas of the seabed. It is estimated that 80,000 mines plus other German high explosives were dumped in the Baltic after the war. There are also 300,000 tonnes of chemical weapons including arsenic compounds and mustard gas.[7]
