Leman Sandstone SEM Images

Description

This project contains high resolution SEM images of sandstone samples from the Vanguard gas field in the UK sector of the Southern North Sea. The reservoir rock in the Vanguard field is the Leman Sandstone Member of the early Permian, Rotliegendes Group and was deposited during dry or semi-dry aeolian, fluvial or lacustrine environments. The reservoir has been buried to a depth of 2800 m and has been subjected to significant diagenesis creating a complex pore space containing quartz cement, illite, chlorite and partially dissolved K-feldspar in addition to primary grains.
