The Petroleum System  consists of four main Geologic components, source, reservoir, seal and trap plus additional processes necessary to generate and store hydrocarbons in the subsurface. Their presence is required to generate a viable EXPLORATION TARGET.

In and around Orkney all the major elements of the Petroleum System are present.
