FIGURE 11. (A) Inline 807 is a depositional strike section through the reservoir (see Figure 1 for location). The proximal portion of the Diana Subbasin, which includes the Diana 2 and Diana 3 well penetrations, is represented by high-amplitude, continuous seismic character above the gas-oil contact. The observed amplitude dimming toward the Diana 3 location is fluid related (change from gas to oil) and is not associated with variations in net-to-gross. Subtle variations in isochron are observed for the A-50 and may suggest a more channelized reservoir, but it is not conclusive. (B) The forward seismic model of the proximal fan channels from the Skoorsteenberg Formation is very similar to the seismic character observed on the seismic line through the Diana 2 and Diana 3 wells. (C) This similarity between the forward seismic model of the proximal fan outcrop and the actual seismic data supports the channelized, proximal fan interpretation for the A-50 reservoir in this portion of the basin.
