The Triassic Sherwood Sandstone is the principal reservoir in the Wytch Farm Field, located in Dorset, southern England. Composed of predominantly arkosic alluvial sandstones, it has excellent reservoir qualities but includes significant mudstone, calcrete and calcrete conglomerate baffles which affect the vertical passage of fluids. The identification of 'flow units' within this sequence has helped to determine appropriate layers for use in the reservoir simulation model. These flow units were defined using core data from 24 of the 48 wells and by log correlation. The well information was supplemented by outcrop data to help elucidate the geometry of individual layers.
