Saudi Arabia. This study was a first step towards building a quantitative 3-D geologic model for use as an analog to the lower Arab-D reservoir. Outcrop analogs like this one are critical to understanding reservoir performance on the flow-unit scale (1 to 30 m). Although seismic data allow geologists to gain information about large-scale reservoir compartmentalization (>30 m), flow-unit scale reservoir parameters are far below seismic imaging capability and inter-well spacing.
