FIGURE 6. Overall this is a very layered reservoir with most of the amalgamation of these broad channels occurring where erosional axes cut into underlying sand bodies. Bed-length data based on detailed bed-by-bed correlations show these sandstones have lengths much greater than the length of the outcrop. In contrast, 80% of all mudstones are less than 0.3 m (1 ft) thick and have bed lengths less than 200 m (655 ft). Although this is a relatively high net-to-gross reservoir type with excellent lateral continuity, the vertical continuity would be moderate to low. Bed continuity, connectivity, and vertical and lateral facies variability data such as this were collected from a variety of channel types to condition the object-based geologic model for the Diana field (location: Kilbaha Bay) (modified from Sullivan et al., 1998).
