The Middle Jurassic Sleipner Formation is sub-divided into three units in the Beryl Embayment area of the North Sea. ... The 'Estuarine Succession' forms the bulk of the Formation, and is composed of seven facies, grouped into three facies associations representing sub-tidal, inter-tidal and salt marsh sub-environments.
